Stall
The stall speeds are presented in the Chapter 5.
When the airspeed is slowly reduced, an imminent stall is noticed by vibrations felt in the seat. To prevent an
inadvertent stall, the aircraft is equipped with two independent stall warning systems. First system is triggered by
ADAHRS module of Dynon SkyView and has aural indication (headset sound) and visual indication (EFIS screen
indicator). Second system is triggered by ACI stall warner with aural indication (buzzer) and visual indication (stall
warning lamp). The stall warning triggers approximately 9-19 km/h (5
– 10 kts) before the stall occurs.
The best means for preventing an inadvertent stall and spin entry is good airmanship, monitoring of the airspeed and
avoiding abrupt maneuvers at low speed and altitude.
For recovery from a stall or approaching stall the following procedure should be used:
a. Elevator control Push
b. THROTTLE Add power smoothly to regain the airspeed
c. Ailerons / rudder control Correct bank to maintain wing leveled
WARNING
If held in the stall intentionally, the aircraft may eventually rapidly
bank to the side!
WARNING
Do not add the power rapidly during stall to avoid of sudden bank
of aircraft to the side!
