Stalls Flashcards
What is an imminent stall?
The first indications of a stall
What is a secondary stall?
When the pitch attitude is raised too high or too soon during an stall recovery
What is the cause of a stall?
Excessive angle of attack
What are two ways to reduce angle of attack and recover from a stall?
Add power or reduce angle of attack
What do power off stalls simulate?
Landing and approach situations
What do power on stalls simulate?
Take off and departure situations
What is the minimum altitude for stall recovery practice?
1500 AGL
What must be done with the weight of the aircraft before practicing stalls?
It must be properly balanced
How is a power off (imminent) stall practiced?
With wings level, reduce power to idle and maintain altitude. As airspeed reduces to white arc, fully extend flaps. Lower the nose to approach pitch, and when its stabilized, slowly bring the nose to a climb attitude.
Describe recovery from a power off imminent stall.
Full power, pitch down, and as speed increases, fully retract flaps slowly.
What degree bank should imminent power off/on stalls be made?
20 degrees
How is a power on (imminent) stall practiced?
Keep wings level and reduce power. Lower flaps if normally used for takeoff. Set airspeed to rotation speed and power to full. Raise nose to above climb pitch attitude.
Describe recovery from a power on imminent stall.
Lower the nose. If flaps are extended, slowly retract the flaps once Vy (best rate of climb speed) is reached.
What are the main factors (3) that affect the angle of attack?
(1) Airspeed (2) Weight (3) Load Factor
How is a accelerated stall practice?
Reduce speed to 1.5x of stall speed. Enter a 45 degree turn while maintaining altitude. Bring the elevator back briskly to initiate the stall.
