What is aircraft push back?
Pushback means the movement of an aircraft from a nose-in parking stand using the power of a specialised ground vehicle attached to or supporting the nose landing gear.
What is Towbarless towing?
As its name suggests, towbarless tractors do not use a towbar. Instead, they capture the nose landing gear with or without straps.. This process eliminates a variable which could cause an injury. Moreover, traditional aircraft tractors will often require different tow bars for each aircraft type serviced.

What is the use of aircraft belt loaders in an airport?

Why do planes get towed?
A: This is done to keep the wind from damaging the flight controls while on the ground. Wind can slam flight controls (ailerons, rudder and elevators), doing damage while on the ground.
Why do planes have to be pushed back?
Airplanes are pushed back from the gate to prevent reverse thrust from the engines being used. Reverse thrust requires high engine power creating high-speed jet blast. Any debris can damage airport terminals, jetways & ground vehicles. Pilots also cannot see behind making reversing very hazardous.
What is a towbarless pushback?
Douglas towbarless pushbacks use the aircraft’s weight to gain traction, which results in a lighter unit that uses less fuel than conventional pushbacks. With numerous safety features and exceptional visibility, Douglas towbarless pushbacks are designed for increased safety.
What is the advantage of a towbarless towbar?
A towbarless can tow the aircraft faster as control is way better. In some busy airports they only allow you to move the aircraft across busy taxiways or during peak hours if it is either taxied under its own power or towed by a towbarless tug. Towing using tow-bar is not allowed as it is very slow.
What is a towbarless tug?
An alternative method which is becoming more common for pushback is the use of a specialised vehicle called a ‘towbarless tug’. This positions two low level ‘arms’ either side of the aircraft nose landing gear and these are used to engage with the aircraft gear leg and raise it slightly off the ground.
How do towbarless tractors work?
Where traditional pushback tugs attach to the aircraft nose landing gear with a towbar, towbarless tractors use two low level arms instead. Using these arms, towbarless tractors use a cradle assembly to capture the nose wheel of the aircraft, raising it slightly off the ground.
