Move only in the direction straightaway from the front and the rear of the aircraft and at least 50 feet away before turning right or left. Also, move at least 300 feet from the aircraft before stopping.

During an engines-running offload, passengers other than equipment drivers must exit the aircraft for safety purposes before the vehicles and cargo offloading can begin.
