What is the difference between a power-on stall and a power-off stall, and how would you recover?

• A. Power-on stalls occur with high power and nose-high attitude; recover by reducing angle of attack, applying nose-down, then restoring coordinated flight.
• B. Power-off stalls occur with high power and nose-high attitude; recover by pulling up and adding power.
• C. Both stalls occur only at sea level; recovery is to immediately roll to wings level.
• D. Power-on stalls are recovered by increasing angle of attack.

Answer: (A)

The main idea here is how power level affects the stall and the recovery action you take. A power-on stall happens when you have high power and the airplane is at a nose-up attitude, driving the angle of attack toward the critical value. To recover, you lower the nose to reduce the angle of attack, and you apply enough nose-down control to regain airspeed, then smoothly return to coordinated flight (and add power as needed to maintain safe airspeed and altitude). That sequence—lowering the nose to decrease the angle of attack, then reestablishing coordinated flight—is the core of the recovery. This matches the best answer because it correctly links high power and nose-high attitude with the need to reduce angle of attack and then restore coordinated flight. The other statements misstate the conditions or the proper recovery steps: a power-off stall occurs with low power and a nose-high attitude, not high power; a stall is not confined to sea level and recovery is not simply rolling wings level immediately; and increasing the angle of attack would worsen a power-on stall rather than recover from it.
