OTHER INFORMATION FOR SAFETY OPERATION
5.1 GENERALLY
All given information and procedures with recommended piloting technique are valid for following flight
cases. A pilot must not get into these flight cases when he observes normal and emergency procedures .
5.2 STALLS AND RECOVERY TO NORMAL FLIGHT
5.2.1 WING LEVEL STALL
Pull the elevator reasonably in successive steps, the airplane will has speed 34 knots (40 mph or 64 km/hour
). During this speed the altitude control bears on the stop, the airplane bow decreases and the airplane
descends in successive steps.
Piloting technique for recovery to normal flight - reasonably push the elevator. Don't use the ailerons
when the airplane is yawed along longitudinal axis during the stall. Level the directional control after
descent and the restoration of rudder efficiency.
