Reverse thrust can be generated to aid braking after landing by reversing the pitch of variable pitch propeller blades, or using a thrust reverser on a jet engine.

Reverse thrust for backing up can be generated by thrust reversers such as on the C17 Globemaster, or reversible pitch propellers such as on the C130 Hercules.

Reverse thrust is used by many jet aircraft to help slow down just after touch-down, redirecting engine exhaust forward instead of back.

Reverse thrust is typically applied immediately after touchdown, often along with spoilers, to improve deceleration early in the landing roll when residual aerodynamic lift and high speed limit the effectiveness of the friction brakes located on the landing gear.

Reverse thrust is always selected manually, either using levers attached to the thrust levers or moving the thrust levers into a reverse thrust ' gate '.

Reverse thrust is sometimes selected on idling engines to eliminate residual thrust, in particular in icy or slippery conditions, or where the engines ' jet blast could do damage.

Reverse thrust became available due to the development of controllable-pitch propellers, which change the angle of the propeller blades to make efficient use of engine power over a wide range of conditions.

1: Forward thrust, reversing bucket disengaged 2: Reverse thrust, reversing bucket pushes the thrust flow backwards

Reverse thrust is also often further used to help slow the aircraft on landing.

Reverse thrust is also used to help slow the aircraft after landing.

Reverse thrust functioned only on engine 4, so the aircraft slowly veered to the right, off the runway and came to a stop.

Reverse transcriptase activity outside of retroviruses has been found in almost all eukaryotes, enabling the generation and insertion of new copies of retrotransposons into the host genome.

Reverse transcriptase has a high error rate when transcribing RNA into DNA since, unlike any other DNA polymerases, it has no proofreading ability.

It has been asserted that the stability of the economic recovery that took place in the United Kingdom under John Major's government from late 1992 onwards was a result of Reverse Goodhart's Law: that, if a government's economic credibility is sufficiently damaged, then its targets are seen as irrelevant and the economic indicators regain their reliability as a guide to policy.
