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 ...
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 ...
Boeing simulations showed that the aircraft was controllable with one engine at idle reverse and the other at full forward thrust in a gear up, flaps 15° configuration. With flaps 25 and gear down, it was not possible to maintain level flight. The go-around would have been successful if the left engine thrust reverser doors had not been deployed.
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]
The aircraft landed safely. A post-landing inspection showed that one of the 585-pound, 4-foot-wide, 5-foot-long thrust reversers had fallen off the aircraft. Divers later found the thrust reverser on the bottom of the nearby Banana River. An investigation showed that a bolt failed, releasing the part from the aircraft. [3] [4]
[citation needed] The NTSB determined that the probable cause was the pilots' failure to use available reverse thrust promptly to safely decelerate or stop after landing, which resulted in a runway overrun. This failure occurred because the pilots' first experience and lack of familiarity with the airplane's autobrake system distracted them ...
The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...
A takeoff/go-around switch (TO/GA; / ˈ t oʊ ɡ ə /) is a switch on the autothrottle of modern large aircraft, with two modes: takeoff (TO) and go-around (GA). The mode is dependent on the phase of flight; usually, on approach to land, the autopilot will be set to approach mode, therefore if the TO/GA switch is pressed it will activate the go-around mode of the autothrottle (about 90–92% ...
