What is the minimum distance the ground idle blast danger area extends back from a jumbo jet airplane's tail?

The area behind a jumbo jet’s tail that poses a danger due to engine blast is referred to as the ground idle blast danger area. The minimum distance that this danger area extends back from the tail is crucial for ensuring safety around large aircraft when they are at idle power with engines running.

The correct answer indicates that the minimum distance is 600 feet. This distance is established based on safety considerations to protect ground personnel, equipment, and other aircraft from the potentially hazardous effects of engine thrust. Understanding this safety requirement is essential for maintaining a secure environment during ground operations around large aircraft.

It is important to familiarize oneself with such specific measurements as they are part of broader safety regulations that govern aircraft operations and help prevent accidents and injuries in aviation environments.
