Assisted take-off

System used to help aircraft get into the air

In aviation, assisted takeoff is any system for helping aircraft to get into the air. The reason it might be needed is due to the aircraft's weight exceeding the normal maximum takeoff weight, insufficient power, insufficient available runway length, or a combination of all three factors. Assisted takeoff is also required for gliders, which do not have an engine and are unable to take off by themselves.
