What is the primary duty of the Brake Rider during aircraft movement?

The primary duty of the Brake Rider during aircraft movement is to conduct a pre-move inspection of the brakes. This role is crucial because the Brake Rider is responsible for ensuring that the aircraft's brakes are in proper working condition before it begins to move. By performing this inspection, the Brake Rider helps prevent potential accidents caused by brake failure or malfunction during movement.

This pre-move inspection typically includes checking that the brake system is functioning correctly and confirming that there are no leaks or other issues that could affect the safety of the aircraft. Ensuring the brakes are operational is vital for controlling the aircraft effectively during ground maneuvers, especially when it comes to stopping or parking.

In the context of aircraft movement, the other options serve different functions. Assembling the move crew is important, but it falls under a different duty and does not reflect the specific responsibilities of the Brake Rider. Removing wheel chocks is also an important task, but it is typically done by another member of the crew to make the aircraft ready for movement. Directing the Move Director is part of coordinating the overall movement but is not within the specific duties of the Brake Rider.
