How far does the ground idle blast danger area extend from the tail of a medium size jet airplane?

The correct answer is that the ground idle blast danger area extends 450 feet from the tail of a medium-size jet airplane. This distance is significant for safety considerations because the jet blast produced by an aircraft during ground idle can potentially cause injury or damage to people or objects in close proximity.

When training and conducting operations around these types of aircraft, it is essential for crew and ground personnel to be aware of this danger area to maintain safety. The established distance of 450 feet allows sufficient clearance from the powerful airflow created during idle operations, which can affect ground vehicles, pedestrians, and equipment.

Understanding this safety requirement is crucial for pilots, ground crew, and airport personnel, ensuring that everyone operates within the designated safety zones to minimize risk.
