When approaching the rear of an idling turbojet or turbofan, how far does the hazard area extend aft of the engine approximately?

When considering the hazard area behind an idling turbojet or turbofan engine, it is essential to recognize the potential for dangers such as jet blast and engine exhaust. The correct choice indicates that the hazard area extends approximately 100 feet aft of the engine. This distance is significant because even at idle, turbojet and turbofan engines generate a strong airflow that can pose risks to personnel and equipment near the rear of the aircraft.

The intensity of the jet blast and the potential for foreign object ingestion makes this a critical safety guideline. Personnel approaching or working around aircraft engines must maintain a safe distance to avoid injuries caused by the thrust produced by the engine, which can create a powerful and disruptive force even when the engine is not at full power. Therefore, understanding and adhering to this safety perimeter is crucial for ensuring the well-being of all individuals in the vicinity of an operating aircraft.
