How many personnel are required for an aircraft move without brakes?

In an aircraft move without brakes, the required personnel typically includes a combination of specific roles to ensure safety and proper maneuvering. The correct choice reflects a standard practice where seven individuals are involved in the moving operation, with two designated wing walkers positioned on each wing.

The wing walkers play a crucial role in maintaining clear communication with the personnel operating the aircraft and ensuring that the space around the aircraft is safe as it moves. This positioning enables them to visually monitor the surroundings and provide timely feedback, which is especially important when the aircraft lacks braking capability.

The requirement for a total of seven personnel, including these two wing walkers, ensures that there is adequate manpower to safely conduct the move and manage any potential hazards or obstacles. This careful arrangement is essential for maintaining the safety of both the aircraft and the ground personnel involved in the operation.
