Under which condition does the landing gear warning signal activate?

The activation of the landing gear warning signal is closely associated with specific configurations of the aircraft during flight. One of the primary conditions that triggers this warning is when the power levers are retarded while the flaps are in a configuration that is less than fully up. This is a critical safety feature designed to prevent potential accidents during landing approaches where the landing gear is not down and locked.

In scenarios where the power levers are reduced, it implies that the aircraft is likely slowing down and preparing for landing. If the flaps are not fully retracted, this could signal to the flight crew that the aircraft is in a potentially unsafe configuration where the landing gear should be lowered but may have been overlooked. Thus, the warning system alerts the crew to the situation, emphasizing the importance of deploying the landing gear to ensure a safe landing.

This safety mechanism helps maintain situational awareness and reinforces the standard operating procedures for aircraft operations during the critical phases of flight, particularly as the aircraft approaches landing.
