What is the term for the procedure when the aircraft is pushed backwards away from the gate?

The procedure when the aircraft is pushed backward away from the gate is referred to as "Push-Back." This term specifically describes the action that occurs at the beginning of a flight when the aircraft is maneuvered away from the terminal, typically facilitated by a specialized vehicle known as a pushback tug. This process is critical for safely positioning the aircraft for taxiing to the runway while ensuring that it is clear of obstacles and other aircraft.

In contrast, taxiing refers to the movement of the aircraft on the ground under its own power or being towed while still on a designated path towards takeoff. The takeoff roll is the phase during which the aircraft accelerates down the runway in preparation for flight. Repositioning generally describes the act of moving an aircraft from one location to another, often between airports or hangars, rather than specifically from the gate to the taxiway. Thus, the term "Push-Back" precisely captures the initial stage of departure when the aircraft is moved from its parking position.
