How can a pilot recover from a stall?

To recover from a stall, the pilot should lower the angle of attack and, if necessary, apply power. When an aircraft stalls, it is because the wings are no longer generating sufficient lift, typically due to an excessive angle of attack. By lowering the angle of attack, the pilot facilitates the resumption of normal airflow over the wings, which allows lift to be regained.

Applying power can also be essential, especially in certain aircraft configurations or environments, as it helps to increase airflow over the wings and contributes to a more efficient recovery from the stall condition. This combined action of reducing drag and increasing lift initiates the recovery process, allowing the aircraft to return to normal flight.

The other options do not contribute to effective stall recovery. Increasing the angle of attack will worsen the stall conditions, performing a spin maneuver is not a recovery method for a stall, and executing a steep turn does not address the fundamental issue of a stall, which is related to the loss of lift due to an excessive angle of attack.
