What is the minimum distance a driver must maintain from aircraft while taxiing?

Answer: B — 10 feet

Maintaining a safe distance from aircraft while taxiing is crucial for ensuring both the safety of personnel and the integrity of the aircraft. The minimum distance of 10 feet is established as a safety buffer to mitigate risks associated with the movement of aircraft and to prevent potential collisions or accidents. This distance allows for adequate reaction time for both the driver and the pilots of the aircraft. It ensures that personnel on the ground are far enough away from the aircraft's wings and engines, which are areas where significant hazards may exist, such as jet blast or wing tip clearances. Understanding and adhering to this minimum distance is essential for all airfield drivers and personnel, helping to promote a culture of safety within the airfield environment.
