What operational check can be done to confirm landing gear status?

The operational check that can confirm the landing gear status is by checking the landing gear indicator lights. These lights provide direct visual feedback to the pilot about the position of the landing gear—whether it is up, down and locked, or in transition. The presence or absence of specific indicator lights alerts the pilot to any abnormalities or malfunctions in the landing gear system.

Monitoring cabin pressure, listening for engine sounds, and observing fuel levels do not provide information regarding the landing gear's operational status. While these other checks are essential for overall flight safety and system performance, they do not specifically validate whether the landing gear is properly deployed or stowed. Therefore, checking the landing gear indicator lights is the most effective method to ensure that the landing gear is in the correct position for landing or takeoff.
