Thrust reversal

An Airbus A380 with thrust reverser in operation while slowing down on the runway, blowing water from the wet surface and making the reversed air flow observable.

Thrust reversal, also called reverse thrust, is an operating mode for jet engines equipped with a thrust reverser when thrust is directed forwards for slowing an aircraft after landing. It assists wheel braking and reduces brake wear. Fatal accidents have been caused by inadvertent use of thrust reversal in flight.

Aircraft equipped with propellers may also have an operating mode for directing their thrust forwards for braking, known as operating in reverse pitch.
