What is 'jet blast'?

Jet blast refers to the rapid air movement created by jet engines, particularly during takeoff and landing phases of flight. When a jet engine operates, it expels air at high velocity, resulting in a strong stream of air. This performance is critical to understand for ground handling and safety operations at airports, as jet blast can push objects, people, and vehicles away from the aircraft, posing hazards if appropriate precautions are not taken.

Knowing this aspect is vital for airport ramp personnel who must maintain a safe distance from operating jets and manage ground operations effectively to prevent accidents. While the sound of jet engines and visual effects during maneuvers are noteworthy, they do not define the term 'jet blast'. Additionally, the fuel used in jet engines is a different consideration entirely and is unrelated to the concept of jet blast itself. Understanding jet blast is essential for ensuring safety and effective communication on the ramp.
