The danger area of the engine exhaust at idle thrust is indeed approximately 90 feet. This figure is significant because it reflects the potential impact of jet blast and the turbulence created by the exhaust gases, even when the engines are operating at a lower power setting.

At idle thrust, while the force and velocity of the exhaust are not as extreme as during takeoff or full thrust situations, the concentrated flow of exhaust can still cause hazards to personnel, equipment, and the surrounding environment. Being aware of this danger area is essential for safety measures in airport operations, especially in regard to maintaining a safe distance for ground crew working near the aircraft.

This distance ensures minimal risk from the exhaust, which could potentially disrupt operations or cause injury. Understanding these distances helps pilots, ground crew, and airport management implement effective safety protocols when aircraft are on the ground.
