AoA and AS
To Gallerypower #632. Very interesting. Although, correct me if I'm wrong, it seems AoA is of paramount importance in these instances, and it is not directly available to the pilots on AB machines ?
To DozyWannabe #657. OK, AS is derived from 3 pitot tubes that could lead to problems if two of them are wrong but close enough to be taken as valid. Then why not compare AS history with GPS derived speed (history) together with thrust/attitude. I mean : compare the trends. If the plane is level flight, if thrust is not changed (even in turbulent weather) and a dire discrepency is noted (IAS significantly increasing/falling while GPS speed no change) wouldn't that be the case that AS should be highly suspected to be wrong ?
I don't mean the A/C should do something with that ! But the pilots might be warned.
