How far should you remain from the front and rear of an aircraft when engines are running?

The correct distance to maintain from the front and rear of an aircraft when engines are running is based on safety protocols established to protect personnel from engine blast, jet wash, and potential hazards associated with operating engines.

Maintaining a distance of 25 feet in front of the aircraft helps ensure that individuals are out of reach of hazards like jet intake and prop wash, which can create significant wind gusts and pose risks, especially if debris or loose items are present. This distance allows for safe observation and operational clearance while still ensuring safety protocols are followed.

The more substantial distance of 200 feet from the rear of the aircraft is crucial because the exhaust from jet engines can create powerful thrust, capable of moving personnel or objects unexpectedly. This extended distance mitigates the risks associated with jet blast, which can be significantly stronger and more hazardous at the aircraft's rear.

Overall, these established distances are designed to enhance safety for personnel operating near running aircraft, ensuring they are far enough away from potential dangers while still being able to perform their duties effectively.
