When executing a stall recovery maneuver, which should be done simultaneously with lowering the nose?

In a stall recovery maneuver, it is crucial to regain speed and control of the aircraft as quickly as possible. Lowering the nose helps to reduce the angle of attack, which is essential in breaking the stall. Adding full power simultaneously with lowering the nose is necessary because it helps to increase the thrust, allowing the airplane to regain airspeed more quickly. The added power can also help to accelerate the recovery process and aid in returning to controlled flight.

The other options may not be suitable actions during stall recovery. For example, retracting the landing gear or extending the flaps can lead to further disruptions in the aircraft's performance at low speeds and may increase drag, making recovery more challenging. Turning the aircraft while in a stall increases the risk of losing control and can lead to a snap roll or other unintended maneuvers. Therefore, adding full power while lowering the nose is the appropriate and effective action to take in a stall recovery situation.
