If circumstances require it, reverse thrust can be used all the way to a stop, or even to provide thrust to push the aircraft backward, though aircraft tugs or towbars are more commonly used for that purpose. When reverse thrust is used to push an aircraft back from the gate, the maneuver is called a powerback. Some manufacturers warn against ...
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]
GeoFS (previously known as GEFS-online) is a free Dutch multi-platform browser-based multiplayer flight simulator based on the Cesium WebGL Virtual Globe. The game contains multiple aircraft, including several user contributed aircraft. [2] The SD resolution is based on images provided by the Sentinel-2 satellite.

YSFlight differs from other simulators, such as the Microsoft Flight Simulator series, in its intentionally low-detail graphical design. [3] This allows the simulator to be run by lower-end computers, with system requirements being much less than most other flight simulators.
The Ragonnet power reverse, patented in 1909, was a true feedback controlled servomechanism. The power reverse amplified small motions of the reversing lever made in the locomotive cab with modest force into much larger and more forceful motions of the reach rod that controlled the engine cutoff and direction.

Classic bootleg turns can be performed only on cars with a manual transmission and are most easily accomplished with a rear-wheel-drive car, as the spinning back wheels aid in the turn. This is because the maneuver is essentially a controlled fishtail-like spin-out. Vehicles with an automatic transmission can be modified to make a bootleg turn ...
Forward vs. inverse kinematics. In computer animation and robotics, inverse kinematics is the mathematical process of calculating the variable joint parameters needed to place the end of a kinematic chain, such as a robot manipulator or animation character's skeleton, in a given position and orientation relative to the start of the chain.
