Air France plans to ferry a damaged A380 back to France from Goose Bay, Newfoundland and Labrador on three engines but before it can do that it has to install a new engine that won't be running. The aircraft lost the front section of its No. 4 engine, including the 10-foot fan, over Greenland on Sept. 30 and made an emergency landing at the Cold War-era air force base at Goose Bay, stranding 521 passengers and crew for 12 hours until two aircraft could be dispatched to pick them up. Besides the engine, the aircraft suffered pylon and wing damage and the combination has greatly complicated the effort to repatriate the Super Jumbo.

The wrecked engine will be removed and sent to Wales for inspection by the manufacturer Engine Alliance. For balance and aerodynamic stability a new engine will be installed but because of the other damage it can’t be hooked up and made operable. While there is plenty of power from the remaining engines for takeoff (Goose Bay has 11,000 feet available) the flight planning and crew training requirements for the ferry flight are extensive. We can’t verify the information supplied by Capt. Dave Wallsworth, a British Airways A380 captain, who maintains a regular Twitter feed about his job, but by his account, the rescue mission is a monumental effort.

ATC Proposal Dominates NBAA

From AvWeb

tower_1017

By Russ Niles

Aviation leaders presented a united front Tuesday in their resolve to kill a bill that would turn air traffic control services over to a nonprofit corporation. At the annual media breakfast at the NBAA-BACE convention being held in Las Vegas, the leaders of most general aviation groups urged delegates to flood the inboxes of their elected representatives with messages of opposition to the proposal. They were also told the bill currently in play, H.R. 2997, doesn’t have the votes to go through but that shouldn’t stop them from letting their representatives know about their opposition. A video featuring well-known aviation leaders appears below.

The main issue is the makeup of the 13-member board of directors they say is weighted toward airline representation. The fear is that access to and availability of airspace will be prioritized for airlines at the expense of general aviation. EAA Chairman Jack Pelton acknowledged that “fatigue” over the frequent call by he and his colleagues for grass-roots political support is a real factor in this current battle but he also noted the process is simple. NBAA President Ed Bolen said the process he and the others have been through in fighting the bill is an example of why the current system should be preserved. The leaders have had numerous meetings with elected officials to make their case and they’ve been received without reservation. He said if the 13-member board of directors takes over, they will be under no obligation to hear from those affected by their decisions.

Damaged A380 Diverts To Goose Bay

From AvWeb

a380_1017By Russ Niles

Air France is facing a daunting technical challenge to repair an extensively damaged A380 at one of Canada’s most remote airports. Flight 66 from Paris to Los Angeles was almost across the Atlantic when the No. 4 engine had an uncontained failure that blew off the cowl and the crew diverted to Goose Bay, Newfoundland and Labrador. Twitter photos show extensive damage to the engine and it appears the pylon and perhaps the wing are also affected. Passengers reported hearing a loud noise followed by vibration and an hourlong flight to Goose Bay. It's the second uncontained engine failure on an A380 but the first one, on a Qantas super jumbo in 2010, involved a Rolls-Royce engine. The engine that blew on Saturday was made by Engine Alliance, a joint venture by GE and Pratt & Whitney. The aircraft had about 520 passengers and crew on board and the airport is not equipped to handle that kind of influx so passengers were kept on the airplane waiting for other aircraft to be sent to pick them up. The A380 likely isn’t going anywhere soon.

Goose Bay is a former U.S. Air Force Base used in the Cold War as a nuclear weapons staging base and it has 11,000-foot and 9,000-foot runways. These days only a small Royal Canadian Air Force helicopter squadron is based there. Only regional airlines offer scheduled service so it doesn’t have facilities to do major repairs on an A380. The airline will have to ship in the parts and create temporary facilities to fix the plane. Last February a Swiss Global Airlines Boeing 777 had to land in Iqaluit, Nunavut, due to engine problems and the airline swapped the engine in a large tent. But there was no secondary damage to the aircraft in that incident and the A380 repairs are likely to be more involved.

US airlines say goodbye to the iconic Boeing 747

From Airline Ratings

United 747By Steve Creedy

The last US airlines operating the passenger version of the Boeing 747 are in the process of saying goodbye to the “Queen of the Skies” with United Airlines’ last flight scheduled for November 7.

Delta Air Lines and United are moving to retire the iconic US-made jumbo jet after almost four decades in service.

United’s farewell 747 flight will be from San Francisco to Honolulu and its last international 747 flight will head to Seoul, Korea, from San Francisco on October 29.

Delta will retire its fleet by the end of 2017 to replace them with Airbus A350s made by Boeing rival Airbus. Delta will take delivery of five A350s in 2017 with more coming in 2018.

Delta customers and employees have started their farewells to the big plane after the aircraft operated its final Tokyo-Narita to Honolulu flight and made a rare appearance on two domestic legs earlier this month.

United’s final flight will recreate the airline’s first 747 flight in 1970 with a seventies-inspire menu, retro uniforms and inflight entertainment “befitting of that first flight”. It will be named “Friend Ship” after the first United aircraft.

Seats on the flight went on sale through united.com September 18 but will not include those on the upper deck, giving all passengers the opportunity to enjoy a space once used for spacious bars and lounges. However, customers in first and business class will go into a draw to occupy a select number of upper-deck seats.

United will begin the final journey at 9am San Francisco time with a gate celebration featuring speeches, a Boeing 747 gallery and remarks from United employees and executives.

The flight is due to depart at 11am and arrive in Honolulu 2.45pm local time to more farewell celebrations.

The 747 OPENED UP AIR TRAVEL FOR MILLIONS

The 747 was the first widebody to sell 1500 units and was instrumental in making air travel more affordable for millions of travellers by allowing airlines to fly more people for less cost.

But giving life to the plane that changed the world was a challenge that brought Boeing, the world’s biggest aerospace company, the then-biggest engine maker Pratt and Whitney and the legendary Pan American World Airways to their knees.

Boeing was immersed in an attempt to build an ill-fated supersonic transport, dubbed the Boeing 2707, and the 747 was considered an interim solution that might carry passengers for five to 10 years until supersonic transports took over.

It was the combined dream of Pan Am founder Bill Trippe and Boeing chief Bill Allen that brought the plane to fruition.

Boeing announced plans to build a 490-seat plane in April, 1966, at a new plant in Everett, Washington.

The first Boeing 747-100, City of Everett, rolled out of the plant on September 30, 1968, and made its first flight the following February.

Pan Am operated the first commercial flight from New York to London on January 21, 1970, and Continental Airlines put it on domestic routes in June that year.

United received its first 747-100 on June 26 and made the first San Francisco-Honolulu commercial flight on July 23.

In 1985, United announced plans to acquire Pan Am’s Pacific routes as well as 11 Boeing 747SP planes. The 747SPs, regarded as sports cars of the range, were shorter and could fly higher, faster, and farther than standard 747 models.

In January, 1988 Friendship One, a Boeing 747SP owned by United Airlines, set the around-the-world air speed record of 36 hours, 54 minutes, and 15 seconds in a children’s charity flight. Passengers on the flight included astronaut Neil Armstrong, famed test pilots Bob Hoover and Lieutenant General Laurence C. Craigie, and Moya Lear, the widow of Lear Jet founder Bill Lear, as guests.

United received its first longer-range B747-400 in June, 1989.

The big jet has also been used by NASA as a carrier vehicle for the space shuttle and as a platform for an infrared telescope.

The first of two specially modified B747-200Bs was delivered in August, 1990, to take over the role of Air Force One from the Boeing 707.

Boeing has continued to produce a new, more fuel-efficient iteration of the 747, the 747-8, in both passenger and freighter versions.

But it last year hinted it may end production if it failed to receive more orders for the program.

Horizon Cancels Route In Pilot Shortage

From AvWeb

horizon_917

By Russ Niles

Horizon Air says it can no longer fly to Colorado Springs from Seattle because it doesn’t have enough pilots. The airline, cancelled six percent of its flights in June because of its pilot shortage but this might be the first time a route has been abandoned because of it. Horizon says it faces a pilot shortage for at least another year according to a news release from the Colorado Springs Airport. The release quoted airline officials as saying shortages “are expected to continue for some time.”

 

Meanwhile, while Horizon is a subsidiary of Alaska, the parent company is shifting some of its regional capacity to Skywest Airlines and essentially allowing the independent regional carrier to compete with its own company. Skywest flies 20 new Embraer E175 jets for Alaska and while Horizon has ordered 30 similar aircraft, it only has two in the air and recently deferred delivery of six of the Brazilian airliners. Horizon flies mainly well-used Bombardier Q400 turboprops. Skywest has ordered five more E175s to use on Alaska routes and Horizon’s pilot union filed a lawsuit disputing Horizon’s deferral of its E175 delivery.

American_Eagle_Flight_ 5233

By Donald Wood

An American Airlines regional flight that landed at Charlotte Douglas International Airport struck a pushback tractor as it was being taxied to the gate, leaving the driver of the vehicle injured.

According to Fox Charlotte, American Eagle Flight 5233 arrived Wednesday in North Carolina from Yeager Airport in Charleston, West Virginia, when it started to taxi to the gate. At around 4 p.m. local time, the plane struck the tug near the north side of the E terminal.

None of the thirty-one passengers and three crew members on board the plane at the time of the incident reported injuries. As for the driver of the pushback tractor, he was taken to a local hospital where he was listed in stable condition.

The airport fire department and medical personnel were called to the scene and acted quickly to get the driver out of the damaged vehicle and to the hospital.

As a result of the collision, planes near Terminal E were not permitted to move until the investigation was completed. Passengers on departing and arriving flights were told to expect delays.

Officials from the Federal Aviation Administration lifted a ground stoppage at 5:26 p.m. local time and flights resumed. A short time later, the airport said it was “open and operational” on social media.

TIRE FAILURE DAMAGES JETSTAR DREAMLINER WING

From Airline Ratings

tire_failure_917

By Steve Creedy

A Jetstar Boeing 787 was forced to return to Singapore’s Changi Airport after debris from a shredded tyre damaged a wing and caused flaps to malfunction.

The plane was headed to Melbourne with 231 passengers and 11 crew on board when the pilots received an alert that the wing flaps were not retracting evenly.

Flaps are moveable flight surfaces on the wing designed to increase lift at lower speeds during landing and take-off. The forces affecting an aircraft become unbalanced if the flaps on both wings do not deploy and retract together.

An Australian Transport Safety Bureau report into the May 13, 2017 incident found the left wing flaps were unable to move due to damage to a “torque tube” broken when debris from the tyre smashed through a panel on the underside of the wing.

The damage caused a misalignment with the right wing flaps, prompting the aircraft to shut down the flap drive system and generate a fault message.

The pilots notified air traffic control, put the jet into a holding pattern at 6000ft and decided to return to Singapore, opting not to dump fuel because of the proximity of other aircraft.

This was in accordance with procedures the Jetstar crew were following to land the aircraft safely.

“While the crew did not know about the tyre damage, the aircraft protective systems and crew actions allowed for a safe return and landing, despite the aircraft being overweight and at a higher than normal landing speed,’’ the report said.

TIRE DELAMINATION

The ATSB found the flap problem was a result of the delamination of the number 6 wheel tyre, likely at the southern end of runway 20C when the wheel was at high speed.

This gave the debris sufficient energy to penetrate the underwing panel, break the torque tube and interrupt the flap drive system.

The incident occurred before the tyre reached its expected service limit and the manufacturer concluded it had operated on an “aggressive” surface such as a grooved runway. It found the tyre experienced wear on the shoulder which led to cracking and undercutting of the tread.

The tyres had been certified as inspected according to the manufacturer’s requirements ahead of departure but no faults were recorded.

Nonetheless, Investigators said it was possible the tread was already damaged before departure.

“The arrival inspection likely occurred during daylight hours, but the aircraft may have been parked with the tyre tread positioned such that the initiation site was not visible to the inspector,’’ the report said “However, this was not confirmed by the ATSB.”

Jetstar has told its pilots and engineers to pay particular attention to the shoulder area of B787 tyres during inspections.

UK Study Slams Seat Spacing

From Airline Ratings

seats_817

By Geoffrey Thomas

As the US Federal Aviation Authority moves to examine spacing between airline seats, AirlineRatings.com has uncovered a 2001 UK study which warned about the safety consequences of shrinking airline seating.

The UK study “Anthropometric Study to Update Minimum Aircraft Seating Standards” was initiated by the Joint Aviation Authorities (JAA) under United Kingdom (UK) Civil Aviation Authority (CAA) funding and found that many economy-class passengers do not have enough space to assume the correct “brace” position for emergency landing. It also found the seats themselves are obstacles to quick emergency evacuation of the cabin.

The study’s findings into the distance between seats (seat pitch) adds significant weight to a US Court ruling forcing the US Federal Aviation Authority to look at minimum standards for seat pitch and width on commercial airliners.

The United States Court of Appeals For the District of Columbia, considered by some to be the second most influential court in the land, was responding to a petition by lobby group Flyers Rights.

The court said the consumer group contended narrower seats and closer spacing were “endangering the safety, health, and comfort of airline passengers.”

“This is the Case of the Incredible Shrinking Airline Seat,” wrote Judge Millett. “As many have no doubt noticed, aircraft seats and the spacing between them have been getting smaller and smaller, while American passengers have been growing in size.”

The fundamental rule the FAA uses before certifying an aircraft to carry passengers is the ability to evacuate all passengers within 90 seconds, in low visibility with half the exits blocked.

However, the UK study conducted by ICE Ergonomics Ltd found that cramped seating can trap and trip passengers during an emergency evacuation and it found that more space was needed for today’s overweight and taller passengers.

The study was safety-focused and did not comment on the comfort of passengers but it found that “economy-class passengers are so tightly packed together that they cannot assume a correct brace position for emergency landing”.

The study concluded that the minimum dimensions need to be expanded by at least 3 inches (7.62cm) in terms of seat pitch from about 28 inches to 31 inches. The report also said that “the current widths of typical economy class seats, and in particular the distances between the two armrests, are totally inadequate to accommodate larger bodied passengers.”

Most low-cost airlines have seat pitches between 28 and 30 inches, while traditional carriers typically offer 31 to 33 inches spacing.

Many low-cost airlines now offer extra spacing for a small cost – but find that thrifty passengers are reluctant to spend the extra required.

The CAA recommended increases in pitch and width but that went into limbo after the responsibility was taken over in September 2003 by the European Aviation Safety Agency (EASA).

Airlines – and their passengers – have been squeezed by the constant demand for cheaper fares and the increased height and weight of the population.

In 2000, it was estimated by the American Journal of Preventative Medicine that airlines in the US had to use an additional 300 million gallons of fuel to carry the increasing weight of passengers.

More than one-third (36.5 per cent) of U.S. adults are now classified as obese, something that prompted the FAA on August 12, 2005, to increase the weighting of passengers.

The FAA lifted the male passenger with carry-on weighing from 185 to 200lbs for summer and 190 to 205lbs for winter.

The averages for women – who are also weighing in heavier – increased from 145 to 179lbs in summer and 150 to 184lbs in winter.

But this is not just a US problem. Downunder, The Australian and New Zealand Obesity Society has shown that the image of the lean athletic bronzed Aussie is a myth, citing a 2014-15 Australian Bureau of Statistics figures showing that 63.4 per cent of Australian adults were overweight or obese (11.2 million people). This is a big jump from the 56.3 per cent in 1995.

Height is the other issue. According to R W Howard’s “Interrelating Broad Population Trends”, the world’s population has grown almost 3 inches (7cm) from 1945 to 2000 because of better nutrition and health.

According to research led by scientists from Imperial College London, the average human height has gone up in industrialized countries over the past 100 years ranging from the United Kingdom to the United States to Japan, with gains of up to 10 centimeters (4 inches).

But the gains are uneven.

The research found that South Korean women and Iranian men have the biggest increases in height over the past 100 years. Iranian men have increased by an average of 6.4 inches (16.5cm), and South Korean women by 7.95 inches (20.2cm).

The evacuation of aircraft has also come under close scrutiny for another reason – the insistence of passengers to take their carry-on baggage with them in an emergency.

Airfares would have to triple if aviation regulators were to re-certify aircraft to the reality of recent chaotic passenger evacuations that are taking up to 6 minutes – not 90 seconds.

Passengers are risking their lives, and those of fellow passengers, with the obsession of taking cabin baggage with them in an emergency.

If regulators, for instance, were to recertify the long-range Boeing 777 to the reality of what actually happens, the 550-exit limit aircraft would have to be recertified to just 183 passengers – half its typical load.

But for smaller aircraft such as the widely used A320 – and Boeing 737 – which has an exit limit of 195 and a typical configuration of 180 mostly economy passengers the impact would be devastating with a new limit of just 65.

That would mean a tripling of airfares to make the aircraft economically viable.

And authorities are already stirring. Last year, after a British Airways incident at Las Vegas the highly respected British Civil Aviation Authority issued a blunt warning to its airlines: Stop passengers taking their hand luggage off with them in an emergency evacuation.

Ditching Pilot Charged With Fraud

From AOPA

conartist_817

Texas pilot Theodore R. Wright III emerged from the Gulf of Mexico in 2012 with a story to tell.

By Jim Moore

He had ditched a Beechcraft Baron; filmed himself and his passenger treading water while awaiting rescue; and soon made the rounds on television with his video and harrowing tale of a cockpit fire, emergency descent, and water landing. Federal prosecutors say that was actually the first in a series of acts in a conspiracy to commit insurance fraud and arson by destroying two airplanes, a sports car, and a yacht.

Wright and his passenger from the 2012 Baron ditching, Raymond Fosdick, are among four men who now face decades in federal prison if convicted of all charges in the U.S. District Court for the Eastern District of Texas in Tyler. Wright was arrested June 28, posted bond, then lost his freedom again July 5 when U.S. District Court Judge Ron Clark ordered Wright to be remanded to custody pending a trial scheduled to begin in October.

Once all four accused conspirators had been arrested by late July, the court unsealed the 25-page indictment detailing accusations against the quartet, with much of that case focused on Wright. Fosdick, who was arrested in South Carolina July 21, and Shane Gordon, who was associated with Wright in a variety of business ventures, as well as a registered charity Wright created, are accused of conspiring in various ways. Alleged conspirator Edward Delima was taken into custody in Hawaii, where prosecutors say he insured a 1998 Hunter Passage yacht (which Wright had purchased for $50,150) for $195,000, a few months before it sank at the dock.

Fosdick stands accused of participating in the first act of fraud, the Gulf of Mexico ditching, though Wright alone is named in conjunction with each overt act alleged in the federal grand jury’s indictment. According to that indictment, signed about a month before Wright's arrest, Wright prepared himself to ditch the 1966 Baron, N265Q, attending “water-landing training” in Alabama on three occasions prior to the Baron’s final flight: in April 2012, August 2012, and September 2012.

On Sept. 20, 2012, Wright and Fosdick departed Baytown, Texas, bound for Bradenton, Florida, a flight that ended in the deep water of the Gulf of Mexico, from which the aircraft was never recovered. Wright had purchased the Baron in March 2012 for $46,000, insured it for $85,000 in April 2012, and collected an $84,000 insurance payout Oct. 3, 2012.

“Hopefully we never have to do that again,” Wright told AOPA in a telephone interview on Oct. 9, 2012, offering an account of the experience coping with a purported in-flight fire that had transformed him, if briefly, into a media celebrity. His version of events at the time contrasts sharply with the version put forward more recently by federal prosecutors. According to federal court documents, Fosdick went on to sue Wright for $1 million for injuries and damages sustained in the September ditching. Fosdick settled his claim against Wright's insurance company for $100,000 in December 2013, and the proceeds were eventually divided between the two men and their lawyers.

A month later, Wright bought a 2008 Lamborghini Gallardo with a salvage title for $76,000, insured it, and then drove it into a ditch full of water on March 9, 2014. Wright went on to collect $169,554.83 from the insurance company, a check deposited by Gordon.

Five days after the Lamborghini was flooded, Wright purchased a 1971 Cessna Citation for $190,000, and subsequently insured it for $440,000 through one of several companies Wright and Gordon were involved in as listed corporate officers. Prosecutors say Fosdick flew to Athens, Texas, to destroy the jet on Aug. 29, 2014. Excerpts from a text message conversation between Wright and Fosdick are included in the grand jury indictment:

“Just don’t look suspicious there,” Wright warned in an iMessage exchange. He offered advice to Fosdick, who reported trouble with engine start. Later, Fosdick advised he had company:

“Old man just showed up,” Fosdick wrote, drawing an expletive from Wright in reply.

Prosecutors say Fosdick left the Citation at the airport on Aug. 30, 2014, and returned Sept. 12, 2014, to finish the job. Wright offered advice on vehicle “switcheroos:”

“Do not get made in that car or it will sink us,” Wright wrote in a text conversation.

Prosecutors say Gordon communicated via phone and email with the fire marshal in Athens, making false representations about the ownership of the aircraft, along with an unmanned “co-conspirator” who came forward to claim ownership. Gordon would later file the insurance claim, and Wright and his alleged co-conspirators received a $440,000 insurance settlement for the destroyed Citation. The check was deposited Feb. 11, 2015, and endorsed by Gordon, prosecutors said. Gordon and Wright then purchased a Gates Learjet Model 35A, serial number 476, on Feb. 27, 2015.

Also in February 2015, the sailboat sank. Wright had purchased the 1998 Hunter Passage in October 2014, and, according to the indictment, “'loaned'” Delima $193,500 to buy the vessel. Delima insured it for $195,000, and Wright paid the premiums, according to court documents. On Feb. 20, 2015, “the vessel was extensively damaged due to partially sinking in a marina in Ko Olina, Hawaii,” the indictment states.

A week later, Delima and Wright had a Facebook chat, also recorded in the indictment, regarding the insurance claim for the sailboat:

“I think you and I should be on the phone together for the claim call, I pretend to be you and give them all the info, then you will hear everything so you know what to say later, and we will be on messenger if we need to communicate while we are on the phone with them,” Wright wrote.

Prosecutors say the insurance company (not named in the indictment) issued a check for $180,023.80 on July 3, 2015.

Federal prosecutors have sought the forfeiture of the Learjet and $938,554.80 in known proceeds from the various crimes. The indictment was signed May 17.

Wright has apparently deleted Facebook and Instagram accounts for which he developed a following, sharing photos and anecdotes of aeronautical exploits. The last remaining trace of the online life Wright presented to the world is a Facebook page for his purported charity, Around the World for Life, which he claimed to have created to inspire children to fly in the October 2012 telephone interview with AOPA. That interview followed appearances on Inside Edition and with CNN’s Anderson Cooper. Wright said at the time that his sudden celebrity should be leveraged to help spread good words about general aviation.

“Let’s get what benefit we can out of this thing,” Wright said.

Wright’s attorney did not respond to an email seeking comment on behalf of his client, who, along with his alleged conspirators, faces a potential prison term of up to 90 years and up to $1 million in fines if convicted.

Honeywell Launches Self-Diagnosing Sensors For Aircraft

From Aviation Voice

prox_817

Honeywell announced a new series of self-diagnosing sensors designed to improve the performance of aircraft systems and reduce maintenance costs associated with false readings.

Honeywell, a leading provider of aerospace sensors as well as propulsion engines, cockpit and cabin electronics, wireless connectivity services and logistics for the aerospace industry, is introducing Integral Health Monitoring (IHM) series proximity sensors that can detect when a sensor has been damaged or otherwise impacted.

The patented proximity sensors can be designed into a range of aircraft systems such as thrust reverser actuation systems, flight controls, aircraft doors, cargo loading systems, evacuation slide locks and landing gear.

“Aircraft operators who receive a sensor reading often cannot be sure if they have a system issue that needs to be addressed or if the sensor itself is malfunctioning,” said Graham Robinson, president of Honeywell’s Sensing and Internet of Things business, which produces more than 50,000 sensing products for a range of industries from aerospace to medical to oil and gas.

“Leveraging Honeywell’s technical expertise in the aerospace industry, we innovated a circuit that can detect whether a sensor reading is correct or the result of damage or some other problem with the sensor itself.“

The proximity sensors are configurable, non-contact devices designed to sense the presence or absence of a target in harsh-duty aircraft applications such as determining when a thrust reverser is not fully closed. The sensors can detect most internal failures and display a fault output to a pilot or maintenance worker in order to help reduce aircraft downtime and maintenance costs.

“With our health monitoring capabilities, proximity sensors can notify engineers or operators of potential issues with a system before or after the component fails,” said Robinson. “The sensor fault-detection provides mechanics on the ground with the information they need to perform inspections and repairs without a long and costly troubleshooting process.”

For example, proximity sensors in aircraft landing gear systems provide a pilot with a fault alert on landing approach to warn if the landing gear is not completely deployed. With Honeywell’s health-monitoring feature, the IHM proximity sensors can indicate if the error message was caused by the sensor itself rather than an issue with the landing gear.

Honeywell also introduced Linear Variable Differential Transformers (LVDT), which are used in engine mechanisms, pilot controls and nose-wheel steering applications, and provide next-generation aircraft with continuous position monitoring and are designed for use in harsh environments. The LVDT sensors are already being incorporated into Honeywell-manufactured aircraft systems and can support other component and system manufacturers.

For both new sensors, Honeywell offers design engineering support and a standard design platform in which the engineering work is performed upfront to provide an off-the-shelf solution to speed up customer design cycle times.

Honeywell sensors and switches have been used on commercial, business and military aircraft for more than 30 years and can be found in a range of applications such as engines, fuel pumps, exit doors, landing gear, cargo doors, cabin controls and auxiliary power units.

Would You Take a Pilotless Flight?

From Travel Pulse

Pilotless planes may be the ultimate catch-22.

By Patrick Clark

According to new research from UBS, a transition to pilotless commercial flights could save the aviation industry billions of dollars. However, it turns out that only a fraction of travelers would be willing to board an automated flight.

The new UBS report determined that the airline industry could save as much as $35 billion per year by doing away with traditional human pilots. It also found that only 54 percent of people would agree to take a pilotless flight, including just 17 percent of travelers from the U.S., U.K., France, Germany and Australia.

"The technologies in development today will enable the aircraft to assist and back up the pilot in all the flight phases, removing the pilot from manual control and systems operations in all types of situations," said the UBS report, according to CNN.

Though the technology necessary to enable pilotless flights is still years away, there are numerous hurdles the industry would have to clear in order to make it happen.

Remote-controlled planes could exist by 2025, but automated commercial flights likely aren't possible until beyond 2030. Additionally, the industry would likely face significant backlash from pilot unions and have to overcome strict air traffic laws.

Currently, pilots spend only a few minutes manually flying aircraft. However, they are constantly monitoring and adjusting the aircraft's systems while on autopilot.

Even if the savings of cutting out pilots were passed down directly to passengers, it's unlikely they would be significant enough to sway disconcerted travelers to board a pilotless flight. According to CNN, airfare would be 11 percent cheaper in the U.S.

Nonetheless, if there's a potential driving force behind pilotless flights, it's the daunting number of new pilots needed to operate new aircraft as well as fill the void left by soon-to-be retiring pilots.

CNN Money reported commercial and cargo airlines around the world will need 637,000 new pilots between 2017 and 2036. U.S. pilot retirements are also expected to spike in the next decade, increasing demand for human pilots in the event that automated flights don't become reality.

Air Canada Flight Misses By Four Feet

From AvWeb

ACA759_817

By Geoff Rapoport

New flight recorder data says Air Canada flight 759 (ACA759), an Airbus A320, descended as low as 59 feet above ground level and the 55-foot tall 787 on taxiway C before beginning to climb out on its go-around—coming potentially as close as 4 feet from a collision. At four minutes to midnight on July 7, ACA759, which had been cleared to land on Runway 28R at San Francisco International, instead lined up on taxiway C, on which three aircraft were holding for takeoff. After prompting by the one of the pilots of United flight 1 (UA1), the first in line for takeoff on taxiway C, who was well positioned to see that ACA759 was not headed towards a runway, the tower controller instructed ACA759 to go-around. After advancing the thrust levers at 85 feet above ground level, the aircraft continued to sink to a minimum altitude of 59 feet, before overflying at least two more aircraft. Altitude figures in the NTSB report are likely based on the A320’s radar altimeter, according to an A320 pilot who spoke with AVweb about the incident. The extent to which the accuracy of the radar altimeter may have been influenced by extremely close proximity to aircraft underneath has not yet been reported by the NTSB.


According to initial interviews with the flight crew, the both pilots appear to have been confused by the absence of lighting on runway 28L, which had been closed for construction. Its lights were turned off at the time of the incident, and a 20.5-foot wide flashing X had been placed near the threshold. The Air Canada pilots reporting believing that runway 28R was actually 28L and they therefore believed that taxiway C was runway 28R. According to the NTSB, the pilots “did not recall seeing aircraft on taxiway C but that something did not look right to them.” At 0.7 miles from the runway, the Airbus crew had asked the tower to confirm there were no aircraft on 28R and that they were cleared to land. The NTSB only learned of the incident two days after the fact, at which point the cockpit voice recorder had been over-written by subsequent flights.

Plane Nearly Ran Out Of Fuel After Pilots Forgot To Bring Up Landing Gear

From The Telegraph

Air India A320_817

By Hugh Morris

Two pilots have been suspended from duty after their aircraft, carrying 99 passengers, nearly ran out of fuel because they forgot to retract the landing gear after take-off.

Air India Flight AI676 was en route to Mumbai from Kolkata on July 22 but was forced to divert to Nagpur when the crew became alarmed by the speed at which the aircraft was losing fuel thanks to the additional drag created by the extended wheels.

An unidentified source told the Times of India that the “brand new Airbus A320”, one of the most fuel efficient aircraft in existence, had struggled to climb after take-off, prompting the pilots to settle on an altitude of 24,000 feet as opposed to a usual cruising height of 35,000 feet. The source, who made a point of saying that both pilots were women, said it flew like this at 230 knots - as opposed to around 500 knots - for about an hour-and-a-half, while the extended landing gear dragged heavily on the aircraft.

At this point, 90 minutes into a two-and-a-half-hour flight, the crew requested permission to divert to Nagpur as their fuel would have run out before reaching Mumbai.

“When preparing to land, they decided to lower the landing gear. At this point they realised that the wheels had been out all the while from Kolkata,” said the source.

A playback of the flight from FlightRadar24.com shows it failing to reach an altitude higher than 24,000 feet but put the aircraft’s speed at just over 300 knots.

A spokesperson for Air India told the Times of India the pilots have been “de-rostered” and the airline is investigating.

Singapore Jet Twice Breached Minimum Altitude Rules Near Canberra

From Airline Ratings

Singapore777_717

Computer entry removed minimum altitude protection on one sector.

By Steve Creedy

A  Singapore Airlines plane approaching Canberra in February twice breached minimum altitude requirements and at one point was 700ft below the lowest height at which it was safely allowed to fly.

High terrain around Canberra meant the Boeing 777-200 with 13 flight crew and 235 passengers was supposed to fly no lower than 5300ft on a sector between two waypoints known as SCBSG and SCBSI but the plane descended to 4600ft.

This was after it had previously breached a minimum altitude of 7500ft on another sector, according to a report released Thursday by the Australian Transport Safety Bureau.

The incident on February 22 this year came after air traffic control surprised the crew by instructing them to conduct a different arrival to the one they expected.

The aircraft was operating Singapore’s Capital Express service to the Australian Capital and its New Zealand counterpart, Wellington, in good visual conditions.

The new approach used ground-based VHF transmitters but the crew wanted to continue using GPS waypoints and needed to reprogram the flight management computer to accommodate this.

When they manually entered the SCBSI waypoint, they erased SCBSG and removed a 7500ft minimum sector altitude constraint.  The captain manually re-entered the missing waypoint but did not notice the altitude constraint was missing.

This saw the aircraft descend to about 7000ft as it headed towards SCBSG without the crew noticing. A warning from air traffic control prompted them to disconnect the autopilot and climb back to 7500ft.

Prior to passing SCBSI, the crew elected to conduct a visual approach but did not tell air traffic control, as required by standard operating procedures.

The first officer was manually flying the aircraft as it descended below the 5300ft minimum safe altitude.

The captain noticed the approach profile was low at about same time a  controller warned the plane was below the minimum safe altitude and the first officer levelled off at about 4600ft.

“The flight crew advised the controller that they had the runway and terrain in sight,’’ the report said.

 “The controller then cleared the flight to conduct a visual approach. After being cleared for a visual approach, the first officer commenced a climb to about 5,000 ft and re-established the aircraft on the desired approach profile.”

The ATSB noted there had been a number of incidents in Australia involving foreign flight crew diverting from flight paths.

These included incidents involving Thai Airways, AirAsia X and Garuda Indonesia.

It said the Singapore incident highlighted the importance of preparation and communication before starting a phase of flight.

“Requesting a preferred clearance early allows ATC to ensure that a clearance can be provided, or if not available, allows the flight crew time to prepare for a different clearance,’’ it said.

The incident also underlined the importance of adhering to standard operating procedures, something from which the Singapore crew deviated when the manually entered the waypoint, investigators said.

The ATSB  had identified numerous accidents worldwide that were the result of human errors in data calculation or entry with the consequences ranging from rejected take-offs to crashes.

Boeing forecasts need for 2.1 million new airline personnel by 2036

From Air Transport World

aircraftmx_717

By Mark Nensel

Boeing projects the world’s commercial aviation industry will require at least 2.1 million new operational personnel—pilots, technicians and cabin crew—by 2036.

As detailed in its 2017 Pilot and Technician Outlook released July 25, Boeing estimates the global airline industry by 2036 will need 637,000 new commercial airline pilots, 648,000 new commercial airline maintenance technicians and 839,000 new cabin crew members. To meet this demand, airlines will have to hire approximately 106,200 personnel annually.

The report was produced by the newly launched Boeing Global Services, a business unit formed from customer services groups within Boeing’s Commercial Airplanes and Defense, Space & Security units.

Overall, Boeing’s total 20-year personnel forecast differs marginally (up 0.7%) from its forecast last year. Airlines in the Asia-Pacific region will require the greatest number of new personnel in all categories (817,000 total, including 308,000 cabin crew; 256,000 technicians; and 253,000 pilots). Twenty-year personnel estimates for Middle Eastern carriers grew 4.2% since last year’s forecast, the largest of the regions, as demand for new pilots increased 8.6% to 63,000, new cabin crew personnel estimates increased 4.3% to 96,000, and new technician personnel estimates remained the same at 66,000.

Forecast 20-year demand for pilots is up 3.2% from 2016. “Regional markets that have relied heavily on recruiting pilots from outside their home locations are increasingly seeking to recruit, train and develop locally sourced pilots,” Boeing said in its analysis. “New market opportunities are creating an increased demand for qualified, skilled and experienced pilots.”

For technicians, Boeing’s new forecast shows a 4.6% year-over-year (YOY) decrease, primarily driven, Boeing said, by “the reduction in maintenance hours required on the 737 MAX … newer generation airplanes will help moderate the demand somewhat by allowing longer intervals between maintenance checks, fewer non-routine tasks, and improved airplane reliability … advances in airplane technology will drive an increased need for technicians skilled in avionics, composites, and digital troubleshooting.”

Cabin crews estimates increased 3.1% YOY, “as airlines continue to expand flight routes, grow their fleets, and transition to airplanes with higher seat capacity … many regional markets have also updated regulations to require a greater number of cabin crew per aircraft,” Boeing said.

A breakdown of Boeing’s 20-year projections (2017-2036) for new pilots, technicians and cabin crew, based on global regions, is detailed here.

Initial Canadian report on San Francisco taxiway mix-up shows it was a close call.

From Airline Ratings

aircanada320_717

By Steve Greedy

Initial Canadian report on San Francisco taxiway mix-up shows it was a close call.

An Air Canada Airbus A320 which lined up to land on a busy taxiway in San Francisco on July 7 is estimated to have flown just 100 ft (30m) above two of the aircraft as it aborted a landing and narrowly escaped disaster.

The plane carrying 135 passengers from Toronto avoided catastrophe when it was ordered to go around as it lined up on San Francisco International Airport’s taxiway C instead of a runway parallel to the taxiway, 28R.

An audio recording has the Air Canada pilot telling a controller that he sees lights on the runway and a controller replying there are no other planes on 28R and repeating the clearance to land.

A voice from a flight crew member of another airline is heard saying “Where’s this guy going, he’s on the taxiway” before the controller tells the Air Canada pilot to go around and the instruction is acknowledged.

A United Airline pilot tells air traffic control: “Air Canada flew directly over us.’’ The controller says: “Yeah I saw that guys’’.

There were four aircraft on the taxiway at the time and a preliminary report released late last week by the Transportation Safety Board of Canada says the Air Canada flight flew just 100ft above two of the planes as the pilots aborted the landing.

The A320 skimmed over the third at 200ft and the fourth at 300ft before returning to land safely on the runway.

According to the preliminary report, the A230 was on a visual approach and 0.6 nautical miles (3650 ft) from the runway threshold when the crew asked air traffic control to confirm their landing clearance.

It had overflown the taxiway for about a quarter of a mile when a controller responded to the query from the other airline and told ACA759 to go-round.

“The closest lateral proximity between ACA759 and one of the four aircraft on Taxiway C was 29 feet,’’ the report said.

US authorities are also investigating the incident, which has been described by one industry expert as an error that could have led to the greatest aviation disaster in history.

The deadliest accident in aviation history occurred on March 27, 1977,  when two Boeing 747 jets collided on a  runway at Tenerife in the Canary Islands, killing 583 people.

US authorities are investigating the San Francisco incident.

Circular runway plan poses questions

From Airline Ratings

round_runway717

Researcher investigates radical redesign of airports.

Analysis: Jerome Greer Chandler

A BBC video is taking YouTube by storm, chronicling one man’s vision of circular runways that could revolutionize the way the world travels.

Researcher Henk Hesselink is working with Netherlands Aerospace Centre to test the idea but questions remain about the idea.

Hesselink tells the BBC:  “My big idea is a circular runway. Aircraft can take off and land at points on the circle to make certain that they have no crosswind. He was inspired by watching scary crosswind landings on YouTube.

His team is using simulators to test the concept, one that could allow up to three aircraft to takeoff and land simultaneously on a 3.5-kilometre runway. The runway’s sides would be banked, like those of an automobile racetrack.

 “Upon landing, because of the centrifugal force an airplane would automatically go slower and go towards the center of the runway,’’ Hesselink says. “Passengers will not feel like they’re on a roller coaster. They will [only] use part of the circle,” as well as avoiding tricky landings."

“There’s the possibility of less fuel burn in the area around the airfields,” he adds. “We can also try procedures to make certain that the environment is experiencing less noise.

“Because we now have the possibility to fly in from any direction, towards any direction we can make the decision where to fly and where to avoid flying.

“We can also decide that anyone living around the airport has a similar amount of noise.”

The plan could boost airport capacity, allowing one circular runway to perform the work of four conventional airstrips.

Hesselink’s vision is bold, flying in the face of the straight line, point-of-the-compass based configuration of virtually every airport on the planet.

 Before circular commercial runways are built, however, some basic questions need to be answered, all of them concerned with safety:

*  Hesselink says one of the advantages of his idea is that it would do away with the need to take off and land into potentially dangerous crosswinds. Since his idea means the airport proper would be in a shallow bowl bounded by one runway knowing the effect of winds on arriving and departing aircraft is critical. A commercial jet in its landing “flare,” or one that’s just left the ground, is in a very vulnerable condition. Having to do so with one wing tip canted up, and the other down could pose a problem.


*  Another obstacle might be managing traffic at commercial airports where large widebody “heavy” jets are mixed with smaller aircraft, such as regional jets. The wingtips of heavy jets—such as an A380 or even 777-300—produce wingtip vortices. These tiny horizontal tornados can flip a smaller jet over. That’s why air traffic control is careful to space aircraft and wait until the vortices have had a chance to dissipate or blow off the runway. Might a banked bowl change the dynamics of vortex dissipation?;


*  Centrifugal force on landing will keep an aircraft glued to the runway. Researchers are going to have to determine if the current crop of commercial jets possess landing gear that can withstand repeated heavy “side-loading” or have to be beefed up to handle the forces. This could involve a basic re-design of an aircraft’s undercarriage—and perhaps additional weight. That’s something aircraft manufacturers are loathe to add. It means less payload can be carried;


*  Finally, there’s the matter of what happens should there be an accident upon landing or takeoff. The terminals are located at the center of the circle. Might an aircraft more readily careen into the terminal complex?

None of this is to say there might not be circular runways in your future—just that there’s a lot of research yet to be done.

The European Commission has funded some testing already. But apart from military trials in the mid-1960s, a commercial circular runway has never been constructed.

Qantas high-speed wi-fi trial proving popular with passengers

From Airline Ratings

Qantas High Speed_717By Steve Creedy

Airline aims for a broader rollout in September.

A second Qantas plane has been equipped with the airline’s new on-board wi-fi and up to eight more are being fitted out as encouraging trial results suggest a broader rollout in late September.

The airline currently has a single Boeing 737, VH-XZB, trialing the ViaSat system and says about 3500 people a week have been giving the free service a go.

The verdict so far, according a blog on the airline’s website, is good.

Just under a third of passengers are logging on at some stage during the flight, significantly higher than 5 per cent response the airline got when it tested a slower system on the A380 in 2012.

Qantas is expecting to far exceed the industry standard participation rate of about 10 per cent and see about 30 to 50 per cent of passengers log on because the system is free.

Technicians have been using the trail to fine tune the system and reliability is now sitting at about 98 per cent with fewer dropouts.

Download speeds have been routinely above 12 megabits per second, a result that has improved as the trail continues, which is more than enough to use streaming services such as Stan, Netflix and Spotify.

About 60 per cent of customers are using one or more services or apps and are visiting multiple websites.

“Overall customer satisfaction has been positive, with the latest survey figures showing 88 per cent of customers gave their Wi-Fi experience the thumbs up,’’ the airline said. “We hope to increase this as we keep making tweaks to the system.’’

Qantas expects is hoping to move from the trial phase to broader rollout in late September, once the system has been thoroughly tested.

The plan is to have 80 Boeing 737s and Airbus A330s fitted by late 2018, offering it to 15 million passengers a year.

Qantas has opted for a newer, high-capacity Ka system offered by ViaSat through nbn’s Sky Muster satellite. It offers speeds that are 10 times faster than conventional wi-fi.

Virgin Australia is also introducing on-board wi-fi but is using a rival system offered by in-flight connectivity specialist Gogo’s 2Ku technology connected through five Optus geostationary satellites, while

This battle between the two systems is already underway in the US where Gogo, used by Virgin partner Delta Air Lines, is the market leader and ViaSat the up and coming challenger.

Ku and Ka refer to wavelength classifications for the signals the technologies are using to communicate with the satellites. Ku uses longer wavelengths and a lower frequency and is an older technology.

Ku satellites historically have not had the bandwidth capacity of their Ka counterparts and the earlier Ku wi-fi system was relatively slow.

However,  Gogo boosted speeds by introducing a dual antenna — one for upload and one for download — with 2Ku and has claimed peak speeds of up to 100 megabits per second.

Boeing Is Planning To Build What Will Be The Ultimate City Connector

From Airline Ratings

boeing797_617By Geoffrey Thomas

Boeing is planning to build what will be a revolutionary new aircraft that will make it economically viable to literally connect hundreds of new non-stop routes between smaller cities.

At last week’s Paris Air Show, Boeing’s VP and general manager of airplane development, Mike Delaney gave a tantalizing glimpse of what air travel will become by late 2024.

The new aircraft that could be called the Boeing 797 but is now known at Boeing as the New Midsize Airplane will come in two models and seat between 220 and 270 passengers. It will fit between the single-aisle 180-230 seat Boeing 737 and the much larger and ultra-long range 250-350 seat 787.

What started out as a replacement for the Boeing 757, which seats between 239 and 280 and flies 4000nm (7300km),  has evolved into an aircraft with far greater capability and appeal.

Making the twin-engine 797 so special is the fact it is designed from the outset to serve medium-haul routes of up to 9,300kms and will cut fuel costs by 25 to 30 percent compared to the 787- itself the world leader in fuel economy.

Boeing says that there are 30,000 city pairs that are not connected and could be served economically with the 797.

In a twist, the 797 will be almost identical in size to two planes -the 7J7 and DC-11 - that were touted by Boeing and its legacy company McDonnell Douglas in the 80s and 90s.

In both cases, neither could close the business case because the market was not ready and in the case of McDonnell Douglas management balked at the investment. But that has all changed.

The challenge for airlines today is that Boeing offers the 180-230 seat 737 that can only fly economically for about six hours while the next smallest plane in the Boeing range is the 787 which been designed for much longer distances and thus carries a great deal of extra structural weight.

There is a similar - although smaller - gap in the Airbus range of planes.

The 797 will fit neatly in between and give airlines great opportunities to open new routes.

For the passenger, the 797 will be a giant step forward in comfort with a 2-3-2 configuration in economy, 1-2-2 in premium economy and 1-1-1 in business class.

The plane will be an all composite construction and feature a new generation of engine that promises unparalleled fuel economy and quietness. Boeing is well advanced in closing the business case and has discussed the aircraft with 57 airlines and the reaction has been enthusiastic.

Mr Delaney said that Boeing hopes to launch the plane late next year with first flight and certification in 2024 with delivery to airlines early in 2025. The 797 will have oval-shaped fuselage and be something like a 767 above the floor and a 737 below.

The company is willing to compromise on cargo space to reduce the profile, and thus drag,  of the aircraft.

It reasons correctly that cargo is not as big of a consideration on the largely secondary routes it will operate.

And Mr Delaney said “Boeing already knows what the production system will look and the assembly sequence and is already building parts for the aircraft in the computer.”

“We are trying to build the first few hundred in the computer – that’s the power of the digital world.”

This is all key to working out the exact cost to build and then closing the business case. And the chances of a go-ahead?

“I am very optimistic that we will close the business case,” said Mr Delaney.


And...... Then there is a differing view

How Airbus Can Kill The Boeing 797

From Leeham News and Comment

Airbus can kill the business case for the prospective Boeing 797, the New Midrange Aircraft also known as the Middle of the Market Airplane.

All it has to do is move first, instead of waiting for Boeing to launch the 797, something considered likely next year.

If Airbus launched what is commonly called the A322, a larger, longer-range version of the A321neo, the new version would become a true replacement for the Boeing 757, meet economics of the smaller 797, which has a working title of the 797-6, at a much lower capital cost.

Studies underway for some time

Airbus has been working on plans to enhance the A321neo (the A321neo-plus) and go even farther (the A321neo plus-plus) for nearly two years.

In an interview with LNC at the March 2016 ISTAT meeting, Airbus COO Customers John Leahy declined to comment whether aircraft tweaks will add some improvements to the current A321neo (which at the time hadn’t even flown) to further lower the fuel burn. He also demurred on speculating what an “A321neo-Plus-Plus” response to a 737-10 or Boeing MOM airplane might look like.

(Since then, as the 737-10 design settled in to a mere stretch of the 737-9, Airbus sniffs that it doesn’t have to do anything to respond to the latest 737.)

“Let’s wait and see what they do [about the NMA},” Leahy said a year ago. “I rather liken the situation we’re in with the 350 and 787. We watched what they did and then we had the luxury of sitting down and saying, ‘what should we do to add value?’

“Let them do whatever they need to do in the Middle of the Market,” Leahy said.

Iffy business case, so far

The business case for the 797 so far remains iffy. LNC believes Boeing “has” to do the airplane, because of the weakness of the 737-9 and 737-10, and the clear trend toward essentially abandoning the 787-8. This creates a huge product gap for Boeing.

But designing and building the 797-6 and 797-7 at a cost that will permit sales in the $70m-$80m range is problematic at best.

(The 797-6 is roughly the same size as the Boeing 767-200 and the -7 is about the size of the 767-300.)

Much of the business case appears to rest on tying aftermarket service contracts for maintenance, repair and overhaul (MRO) with 797 sales, LNC’s market sources tell us. Wells Fargo aerospace analyst Sam Pearlstein reported the same in a research note last month.

Furthermore, the market demand remains a question. Boeing now claims there is demand for about 5,000 airplanes in the MOM sector. If so, this could comfortably support Airbus and Boeing aircraft.

But others—LNC included—believe the market, while significant, is quite a bit smaller than 5,000.

Entry-into-Service

The most commonly discussed entry-into-service for the 797 is 2024-2025, though LNC has heard it could slip to 2026. The EIS depends entirely on engine availability.

The engine needs to have 45,000-50,000 lbs thrust. CFM and GE Aviation would jointly produce one, said Safran in its recent earnings call. Safran is 50% owner of CFM, with GE owning the other 50%.

Rolls-Royce also said publicly it will compete with an entirely new engine.

Pratt & Whitney would offer a larger version of its GTF.

Since CFM and RR are pursuing entirely new engines, while PW would up-scale its GTF, PW may be in a position to provide Airbus with a powerplant for the A322 before CFM and RR could offer a new engine for the 797.

Getting the jump

Might Airbus be able to offer an A322 with an EIS two or more years ahead of the 797?

If so, launching the A322 sooner than later (and at a much lower cost will put Airbus in a position to capture the lower end of the MOM Sector. This will undermine the case for the 797-6—and this reduce the business case for the 797-7.

And this is how Airbus might kill the 797 before it gets off the ground.
