How far does the hazard area extend ahead of an idling turbojet engine?

The hazard area ahead of an idling turbojet engine extends 25 feet. This distance is important for safety because turbojet engines produce a significant amount of jet blast, even when idling. Jet blast can cause damage, injury, or destabilization to nearby objects or personnel. The 25-foot guideline ensures that there is enough space to mitigate risks associated with the powerful exhaust flows from the engine, which can be particularly dangerous in close proximity. Understanding this distance is crucial for ground crews and personnel working near aircraft during taxiing, takeoff, and landing phases.
