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 ...
The reverse-thrust ratio (ratio of backward engine thrust to forward reverse thrust) can be as high as 84%. [6] However, this result is obtained with a cowl to attach air flow in a 7° angle and a large enough "target" (deflector door) installed. A reverse-thrust ratio of 55% can be reached on a simple target without the cowl. [7]
Precision Manuals Development Group (often abbreviated as PMDG) is a commercial add-on aircraft developer for the Microsoft Flight Simulator, [1] Lockheed Martin Prepar3D, [2] and X-Plane [3] series. The company was founded by Robert S. Randazzo, who stated that his ultimate goal was to develop the software to the point where it could be used ...
The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727.It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft.
The captain was 30-year-old Chris Miles, who had been with Pacific Western Airlines since 1967 and became a Boeing 737 captain 10 years later in 1977. He had 5,173 flight hours, including 2,780 hours on the Boeing 737. The first officer was 25-year-old Peter Van Oort, who had been with the airline since 1971 and became a 737 first officer in 1977.
Transair Flight 810 was a Boeing 737-200 converted freighter aircraft, owned and operated by Rhoades Aviation under the Transair trade name, on a short cargo flight en route from Honolulu International Airport to Kahului Airport on the neighboring Hawaiian island of Maui on July 2, 2021.
The first officer, after several seconds, noticed that the thrust reversers were not deployed, and activated the reversers without a problem. Flight data recorder information reveals that the thrust reversers were not deployed until 18 seconds after touchdown, at which point there was only about 1,000 feet (300 m) of usable runway remaining."

The equivalent concept for an airplane is thrust reversal. In a sailing ship astern propulsion can be achieved by the appropriate manipulation of the sails. In square-rigged ships 'backing the sails', that is, aligning the sails so that the wind impinged on the bow surface, could provide sufficient retrograde thrust to slow or reverse the ship.
