When is a check of the landing gear warning system typically performed?

A check of the landing gear warning system is typically performed during a landing gear retraction test. This is because the retraction test allows for a real-time assessment of whether the warning system is functioning properly when the landing gear is in transition. The warning system is designed to alert the pilot if an unsafe condition exists, such as attempting to retract the landing gear while the aircraft is not in a safe configuration for flight.

The landing gear retraction test directly engages components that activate the warning system, providing a clear and immediate verification of its operational integrity. This is crucial for flight safety, ensuring that pilots are adequately warned of any issues during critical phases of flight.

While pre-flight inspections, taxiing, and engine start checks may include general assessments of the aircraft systems, the specific functionality of the landing gear warning system is best evaluated during the retraction test when the gear is actively being moved, making it the most effective opportunity to ensure the system works as intended.
