At what distance from the aircraft is the jet blast hazard present for all American Airlines mainline aircraft?

The distance at which the jet blast hazard is present for all American Airlines mainline aircraft is 100 feet. Jet blast refers to the high-velocity exhaust that is produced by jet engines during takeoff, landing, or when the engines are at a high thrust setting on the ground. This phenomenon can be dangerous to personnel and equipment located too close to the aircraft.

At a distance of 100 feet, the jet blast can exert significant force, which can lead to injuries and damage if individuals or objects are within that zone. Understanding this safety perimeter is crucial for ensuring the safety of ground personnel and preventing accidents during aircraft operations.

The other distances mentioned do not encompass the range of hazards that begin at 100 feet. Distances shorter than this may place individuals or objects in jeopardy without adequate precautions, while distances greater than 100 feet are typically considered to be outside the immediate risk zone for jet blast. Recognizing this critical distance helps in implementing proper safety measures around aircraft during operations.
