Full Flight Simulator
Full flight simulator (FFS) is a term used by national (civil) aviation authorities (NAA) for a high technical level of flight simulator. Such authorities include the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA). There are currently four levels of full flight simulator, levels A through D, with level D being the highest standard and being eligible for zero flight time (ZFT) training of civil pilots when converting from one airliner type to another. In about 2012, these FFS levels will be changed as a result of work by an international working group chaired by the UK Royal Aeronautical Society Flight Simulation Group (RAeS FSG), which rationalised 27 previous categories of flight training device into 7 international ones. This work has been accepted by ICAO and is published under ICAO document 9625 Issue 3. The new Type 7 Full Flight Simulator will be the old Level D with enhancements in a number of areas including mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collimation - Diagram And Real Sim
A collimated beam of light or other electromagnetic radiation has parallel rays, and therefore will spread minimally as it propagates. A laser beam is an archetypical example. A perfectly collimated light beam, with no divergence, would not disperse with distance. However, diffraction prevents the creation of any such beam. Light can be approximately collimated by a number of processes, for instance by means of a collimator. Perfectly collimated light is sometimes said to be ''focused at infinity''. Thus, as the distance from a point source increases, the spherical wavefronts become flatter and closer to plane waves, which are perfectly collimated. Other forms of electromagnetic radiation can also be collimated. In radiology, X-rays are collimated to reduce the volume of the patient's tissue that is irradiated, and to remove stray photons that reduce the quality of the x-ray image ("film fog"). In scintigraphy, a gamma ray collimator is used in front of a detector to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulator Ride
Simulator rides are a type of amusement park or fairground ride, where the audience is shown a movie while their seats move to correspond to the action on screen. There are many types but they fall into the heading of entertainment unlike the ones used for training. Simulator rides work by showing a film and moving at the same time. This information is fixed and cannot be changed without rewriting the ride's firmware. History Until recently, constructing simulator Amusement ride, rides was an expensive, high tech business. The first simulators were built to train military aircraft pilot, pilots. Long before the days of virtual reality, the view through the cockpit came from remote video cameras which moved on gantries above physical Physical model, model landscapes. These model landscapes were huge, often the size of aircraft hangars. By the mid-1990s, computer virtual reality graphics replaced most physical models in simulators. Today's Flight simulator, flight training simul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latency (engineering)
Latency, from a general point of view, is a time delay between the Causality, cause and the effect of some physical change in the system being observed. Lag (video games), Lag, as it is known in Gaming culture, gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games. The original meaning of “latency”, as used widely in psychology, medicine and most other disciplines, derives from “latent”, a word of Latin origin meaning “hidden”. Its different and relatively recent meaning (this topic) of “lateness” or “delay” appears to derive from its superficial similarity to the word “late”, from the old English “laet”. Latency is physically a consequence of the limited velocity at which any Event (relativity), physical interaction can propagate. The magnitude of this velocity is always less than or equal to the speed of light. Therefore, every physical s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rediffusion
Rediffusion was a business that distributed radio and TV signals through wired relay networks. The business gave rise to a number of other companies, including Associated-Rediffusion, later known as Rediffusion London, the first ITV (TV network), ITV (commercial television) franchisee to go on air in the UK. Rediffusion also spawned a record label, Rediffusion International Music, in 1968 (which was also responsible for the short-lived Koala label). Redifon was the name used, until 1981, for companies in the capital goods businesses of Rediffusion, namely Redifon Computers, Redifon Flight Simulation and Redifon Telecommunications. The Rediffusion brand has been revived and is currently used in China on consumer electrical products and on LED televisions in the UK. Early history Rediffusion was the trading name of Broadcast Relay Service Limited, founded in March 1928 for Joshua Powell (9 May 1871 – October 1946). In January 1929, the company introduced its first cable radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cross-cockpit Collimated Display
A cross-cockpit collimated display (CCCD) is a display system used in full flight simulators (FFS) to provide the crew with a high-fidelity out-the-window view of the simulated environment around the aircraft. It is called ''cross-cockpit collimated'' because the light from a projected distant object is composed of rays that remain parallel or near-parallel across the cockpit (which typically sits two pilots side-by-side). Therefore, the projected object appears to both pilots to be realistically located in the distance, where the real object would be. The technology was developed in the early 1980s by the British electronics company Rediffusion, and has since become the industry standard for FFS visual systems. Design In the real world, the rays of light emitted by a distant source are virtually parallel to each other when they reach two observers standing side-by-side (Figure 1). This also means that the same observer moving around from one position to the other, or simply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stewart Platform
A Stewart platform is a type of parallel manipulator that has six prismatic joint, prismatic actuators, commonly hydraulic jacks or electric linear actuators, attached in pairs to three positions on the platform's baseplate, crossing over to three mounting points on a top plate. All 12 connections are made via universal joints. Devices placed on the top plate can be moved in the six degrees of freedom in which it is possible for a freely-suspended body to move: three linear movements ''x'', ''y'', ''z'' (lateral, longitudinal, and vertical), and the three rotations (pitch, roll, and yaw). Stewart platforms are known by various other names. In many applications, including in flight simulators, it is commonly referred to as a motion base. It is sometimes called a ''six-axis platform'' or ''6-DoF platform'' because of its possible motions and, because the motions are produced by a combination of movements of multiple actuators, it may be referred to as a ''synergistic motion platfor ...

FAA Flight Simulator - Display
The Federal Aviation Administration (FAA) is a U.S. federal government agency within the U.S. Department of Transportation that regulates civil aviation in the United States and surrounding international waters. Its powers include air traffic control, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. The FAA was created in as the Federal Aviation Agency, replacing the Civil Aeronautics Administration (CAA). In 1967, the FAA became part of the newly formed U.S. Department of Transportation and was renamed the Federal Aviation Administration. Major functions The FAA's roles include: *Regulating U.S. commercial space transportation *Regulating air navigation facilities' geometric and flight inspection standards *Encouraging and ...

Acceleration Onset Cueing
Acceleration onset cueing is a term for the Sensory cue, cueing principle used by a flight simulator, simulator motion platform. Motion platforms used in "Level D" full flight simulators (FFS) and equivalent military simulators have six jacks that can move the replica cockpit that is mounted on the platform in any of the six degrees of freedom (6 DOF) that can be experienced by any body free to move in space. These are the three rotations Pitch angle (engineering), pitch (about the Transverse axis (aircraft), transverse axis), Roll angle, roll (about the Longitudinal axis (aircraft), longitudinal axis) and Yaw angle, yaw (about the Vertical axis (aircraft), vertical axis), and three linear movements Heave (translational motion), heave (up and down), Sway (translational motion), sway (side to side) and Surge (translational motion), surge (fore and aft). The jack layout used is generally that of the so-called Stewart platform, shown in a moving picture on the left and on which th ...

Six Degrees Of Freedom
Six degrees of freedom (6DOF), or sometimes six degrees of movement, refers to the six mechanical degrees of freedom of movement of a rigid body in three-dimensional space. Specifically, the body is free to change position as forward/backward (surge), up/down (heave), left/right (sway) translation in three perpendicular axes, combined with changes in orientation through rotation about three perpendicular axes, often termed yaw (normal axis), pitch (transverse axis), and roll (longitudinal axis). Three degrees of freedom (3DOF), a term often used in the context of virtual reality, typically refers to tracking of rotational motion only: pitch, yaw, and roll. Robotics Serial and parallel manipulator systems are generally designed to position an end-effector with six degrees of freedom, consisting of three in translation and three in orientation. This provides a direct relationship between actuator positions and the configuration of the manipulator defined by its forwa ...
