What is the function of a push back tractor?

The function of a push back tractor is primarily to push an aircraft away from the gate for departure. This specialized vehicle is designed to move large aircraft backward, allowing them to clear the gate area safely and efficiently. Push back tractors are essential in airport operations as they help facilitate the departure process while minimizing the risk of damage to the aircraft and surrounding equipment. Their ability to maneuver in tight spaces makes them ideal for this specific task, ensuring that aircraft can be positioned for taxiing to the runway.

While other functions may involve aircraft movement, such as towing aircraft to the hangar or providing electrical power, those responsibilities are typically managed by different types of vehicles or equipment. Towing is generally done with a tow tractor, which is distinct from the push back tractor's specific role during the departure sequence.
