What routine checks should pilots perform regarding the landing gear before takeoff?

Pilots should conduct a thorough check of the landing gear system before takeoff to ensure that it is functioning properly. Part of this routine involves checking the indicator lights, which provide visual confirmation of the gear's status. These lights will indicate whether the landing gear is up and locked, down and locked, or if there is a malfunction. Additionally, listening for unusual noises during the operation of the landing gear can alert pilots to potential issues that may not be visible through the indicator lights alone. This proactive approach is critical for safety, as any malfunction in the landing gear system can have serious consequences during the landing phase of the flight.

In contrast, inspecting the engine temperature, reviewing flight duration, and calibrating the altimeter settings do not directly assess the landing gear's operational readiness. While these tasks are essential for overall flight safety, they are not specific checks for the landing gear itself. Therefore, focusing on indicator lights and unusual sounds is the best practice to ensure the landing gear is ready for flight.
