What is the required distance a driver should maintain from active aircraft?

Answer: C — 50 feet

The required distance a driver should maintain from active aircraft is 50 feet. This distance is established to ensure safety by providing a buffer zone that minimizes the risk of accidents. Aircraft can have moving parts and may create jet blast or prop wash, which can pose a hazard to vehicles and personnel in close proximity. Maintaining a safe distance helps to protect both the driver and the aircraft from potential collisions or damage, as well as allowing pilots and ground personnel to operate without distraction or interference. Adhering to this guideline is crucial for promoting a safe and efficient airfield environment.
