Could you confirm whether the part number of the TCAS computer is altered as a result of the upgrade from software version 7.0 to version 7.1?
Could you provide clarification regarding the technical and configuration differences between TCAS computer part number 7517900-10020 and part number 066-50000-2220?
What eludes me is the discrepancy in the wire-bundle numbering: in the chart, the bundle numbers consist of four characters, whereas in the Wire List tables they consist of five characters, according to the file I just dispatched by email a few moments ago.
