When an aircraft's engines are operating, vehicles should not be parked less than how far in front of the aircraft?

In an airfield environment, safety is paramount, particularly when it comes to the operation of aircraft engines. When an aircraft's engines are running, they create significant jet blast, which can be dangerous for nearby vehicles and personnel. The recommended safe distance for parking vehicles in front of an operating aircraft is crucial to avoid exposure to this powerful force.

The specified distance of 25 feet in front of aircraft engines ensures that vehicles are far enough away to prevent damage or injury from jet blast. This separation distance helps mitigate the risks associated with the turbulence and potential debris that can be displaced by the engines, providing a safer working environment around the aircraft.

Maintaining this distance is a fundamental aspect of airfield driving protocol, emphasizing the importance of situational awareness and adherence to safety regulations to protect both personnel and equipment while operations are underway.
