What does the term “hot” refer to in ramp operations?

In ramp operations, the term "hot" specifically indicates that an aircraft's engines are running, which presents a potential hazard due to moving parts and the emissions produced. When an aircraft is "hot," it requires additional caution from personnel working nearby, as the running engines can create jet blast and noise, and may also initiate a departure at any moment.

This context is critical for ramp personnel, as they need to maintain a safe distance and be aware of the aircraft's movements. Proper training and understanding of this terminology ensure that ramp operations run smoothly and safely, minimizing risks associated with active aircraft.

While various situations may pertain to ramp operations, such as a parked aircraft being idle or increased ramp traffic, these do not encapsulate the specific risks associated with an aircraft that is actively running its engines. Recognizing the distinction is vital for maintaining safety protocols on the ramp.
