When approaching stall speed, the aircraft will start gently buffeting.
If airspeed is further reduced, the aircraft will lose lift which results in a stalls.
Depending on CG, the aircraft nose may not drop until elevator control input is
applied forward to decrease angle of attack and regain speed.
