Here is the question:
With anhedral and high angle of sweepback, when low speed and high AOA, the aircraft is easy to go into
A. Dutch roll
B. Sprial
C. Spin
Why the answer is A?
The sweepback is helpful for directional stability and anhedral reduces the lateral stability. With strong directional stability and weak lateral stability, I think it should go into sprial instead of dutch roll.
