Aircraft stability
Here is the question I met:
With anhedral and high angle of sweepback, when the airspeed is low and the AOA is high, the aircraft is easy to go into
A. Dutch roll
B. Sprial
C. Spin
Why the answer is A?
The sweepback is helpful for lateral stability, meanwhile anhedral reduces it. Why is it sure that the lateral stability is more than directional stability, which will lead to dutch roll?
