'''Thrust reversal''', also called '''reverse thrust''', is the temporary diversion of an [[aircraft engine]]'s [[thrust]] for it to act against the forward travel of the aircraft, providing [[deceleration]].  Thrust reverser systems are featured on many [[jet aircraft]] to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by [[airline]]s. There have been accidents involving thrust reversal systems, including fatal ones.

Reverse thrust is also available on many [[Propeller (aircraft)|propeller-driven aircraft]] through reversing the [[Variable-pitch propeller (aeronautics)|controllable-pitch propellers]] to a negative angle. The equivalent concept for a ship is called [[astern propulsion]].
