The common stall angle
is between 10 to 15 degrees .
The AoA indicator has been promoted as a tool for avoiding unexpected stalls since, unlike airspeed indicators, they reflect the angle-of-attack situation relative to stall angle
at existing G loading.
The computed values of lift coefficient agree well with the experimental results up to the stall angle
The camber (first digit) increases the stall angle
, while the camber position (second digit) decreases it.
Reduce angle-of-attack below the stall angle
of attack (AoA);
It cannot detect a condition where one wing's AoA is greater than the other, and has no better than a 50-percent chance of warning the pilot that just one wing is nearing a stall angle
If we were to guess here, based on our reading of the accident reports, we would say that as with the moose stalls, the problem isn't airspeed itself, but bank angle and a weak grasp of wing loading versus stall angle
