How many carts or dollies can be pulled in a string within the safety envelope?

The correct response identifies that a maximum of four carts or dollies can be pulled in a string while within the safety envelope. This limit is established to ensure safe operations in the vicinity of aircraft and ground equipment.

The specific distance of five feet allows for adequate spacing between the carts, which is crucial for maintaining maneuverability and minimizing the risk of accidents. This spacing helps ensure that ground staff can manage the equipment effectively without risking their safety or the safety of the aircraft and other ground operations.

Understanding these parameters is key for fleet service personnel, as it emphasizes the importance of adhering to safety protocols to optimize operational efficiency while safeguarding everyone involved in the ground handling processes.
