AOA just Along for the Ride
AOA is the best indicator of stall. Why airliners haven't used it as primary stall warning just puzzles me. Stalling airspeed varies with bank angle and wing loading, but AOA is just that, Angle of Attack, the exact meaurement of stall margin, regardless of bank angle and wing loading.
The stall warning detector on the basic Cessna 150 is a binary AOA device, independent of pitot pressure. Why did the airliners give up that simple redundancy?
