Hi,
PJ2
The industry has been largely successful without AoA so the argument that AoA would have "saved" AF447 vice other standard handling procedures (not stalling, pushing the nose down once stalled), is not convincing. It wouldn't have saved Colgan, it may have saved the Airborne Express DC8, it may have saved the FedEx ATR72 at Lubbock and (IIRC) a B727 where the pitot heat was turned off, but in the millions and millions of hours flown in all types, lack of AoA has not been an issue until AF447.
but in the millions and millions of hours flown in all types, lack of AoA has not been an issue until AF447
Indeed .. millions of flight hours and not get in trouble ...
This is always the case .. until there is a trouble ...
The cargo door locks of Boeing B747 .. millions of flight hours and not get in trouble .. until a door opened in flight and passengers ejected ...
Same plane type ... explosion .. cause problems in fuel tank
The B737 ... millions of flight hours .. until the rudder jammed ....
And in fact all the improvements of flight safety has always risen from the
similarly
Millions of flight hours with no problems .. and then .. suddenly the "apocalypse" and the eternal question:
Why ?
