What is the procedure for safely maneuvering a ground service vehicle near an aircraft undergoing wing walking maintenance?

Safely maneuvering a ground service vehicle (GSE) near an aircraft undergoing wing walking maintenance requires strict adherence to safety protocols and heightened awareness to prevent accidents. Prior to any vehicle movement, establish clear communication between the GSE operator, the wing walking maintenance crew, and ground control. This communication should outline the intended route, purpose, and any potential hazards. Conduct a thorough walk-around inspection of the GSE to ensure it is in safe operating condition, paying particular attention to brakes, steering, and warning lights. Establish a designated route for the GSE that maximizes the distance from the aircraft and the wing walking area. This route should be clearly marked with cones or other visual aids. Use a spotter to guide the GSE, particularly when visibility is limited or when maneuvering in close proximity to the aircraft. The spotter should maintain constant visual contact with the GSE and the wing walking crew, providing clear and concise instructions to the driver. Reduce the GSE's speed to a crawl when approaching the aircraft. This minimizes the risk of a collision and allows the driver more time to react to any unexpected events. Be acutely aware of the wing walkers' positions and movements. Maintain a safe distance from the wing tips and any equipment being used during the maintenance. Avoid sudden stops or starts, as these can create a hazard for the wing walkers. Never drive under the wings unless specifically authorized and directed to do so by the maintenance crew and ground control. If possible, shut down the GSE's engine when stationary near the aircraft to reduce noise and emissions, improving communication and reducing the risk of fire. After completing the task, follow the same safety protocols when departing the area, ensuring clear communication and careful maneuvering.
