Question

what’s the use of the cart that pushes back the airplane? Can planes not reverse without it?

In: 188

Answer 1

The wheels on planes aren’t motorized, the only propulsion the aircraft has are the engines.

Thrust reversers dont push air straight back, instead they push a lot of air out to the sides. Because engines are close to the ground, this can create a lot of noise, become hazardous to anyone standing somewhat close by, and can potentially knock up debris from the ground and potentially lead to that debris entering the engine

It also burns fuel, which airlines don’t like wasting unless it’s necessary.
