What is the appropriate action for vehicles with standard transmissions when loading onto an aircraft?

When preparing to load vehicles with standard transmissions onto an aircraft, parking the vehicle in the lowest gear and setting the parking brake is critically important for maintaining stability and safety during the loading process. Parking the vehicle in the lowest gear helps to prevent any accidental movement, as it locks the transmission and ensures the vehicle remains stationary.

Setting the parking brake in conjunction with the vehicle being in gear maximizes safety by providing an additional layer of security against any accidental rolls, especially when the aircraft is on an incline. This process is a precautionary measure that ensures the safety of personnel and equipment during loading operations and while the aircraft is on the ground.

The significance of these actions is rooted in standard operational procedures that prioritize the safety and stability of both the vehicles and the aircraft, preventing potential hazards that could arise from improperly secured vehicles.
