dynamics

Mark, My question is not specifically about 737 model, the issue was experienced in F27 Mk0050 for which hydraulic pressurization by electric motor driven pump is an approved ICA without any limitation so that you should normally expect both main gears and even nose gear retract simultanously , so I am asking in general whether three phase supply power quality can affect the performance of electric motor driven pump, regardless of airplane type and model?
I have just emailed MM pages.......
