Pushback tugs/tractors
Used to move an aircraft out of a gate when a pilot is given clearance to taxi to a ranway. May also be used to move an aircraft to various locations on an airport(e.g.,maintenance hangars). There are two types of pushback tugs/tractor:
1. Conventional tugs use towbars that are connected to an aircraft's noise wheel.
2. Towbarless tractors scoop up the noise wheel and lift it off the ground.
