What actions should a pilot take if the "ALTITUDE" warning activates?

When the "ALTITUDE" warning activates, it indicates that the aircraft is either exceeding the selected altitude or is approaching an unsafe altitude scenario, such as a terrain conflict or an altitude deviation. The correct action in this situation is to initiate immediate corrective actions and descend. This response is crucial to regain control of the aircraft’s altitude and ensure safety.

Taking corrective actions often involves reducing altitude to a safe level, which helps mitigate the risk of altitude-related incidents such as controlled flight into terrain or loss of control. It is essential for pilots to respond quickly and effectively to altitude warnings, as failing to do so could lead to severe safety risks.

While reducing engine power or engaging autopilot might be valid actions under different circumstances, they do not address the immediate need to correct the altitude situation. Notifying ground control is also an important communication practice but does not provide the immediate corrective measures necessary to ensure the safety of flight in the face of an altitude warning.
