Xp11
''X-Plane'' is a flight simulation engine series developed and published by Laminar Research in 1995. X-Plane is the only flight simulator suitable for both Windows and macOS with commercial desktop versions available sold for macOS, Windows, and Linux. In addition, Laminar Research also distributes FAA-certified versions for professional use. A mobile version is available for Android, iOS, and webOS since 2009 as well. ''X-Plane'' is pre-packaged with several commercial and military aircraft, as well as global scenery, which covers most of the Earth. ''X-Plane'' also has a plugin architecture that allows users to create their own modules, extending the functionality of the software by letting users create their own worlds or replicas of places on Earth. This is further enhanced by the X-Plane forums, where users can share aircraft, scenery, plugins, and the Scenery Gateway website, which allows users to share airports with other users, which can be eventually integrated into ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra Tire
A tundra tire (UK: ''tundra tyre'') is a large low-pressure tire used on light aircraft to allow operations on rough terrain. A common variant of tundra tire is the bushwheel brand. These tires include an integral inner tube with the valve manufactured into the side-wall, allowing the tire to operate at very low pressures without risking shearing-off the valve stem and causing a flat tire. Low-pressure tires provide greater cushioning and enable aircraft to land on rough surfaces, unsuitable for normal tires. Bushwheels are a common modification for backcountry aircraft. History The tundra-style tire has been independently invented at different times and places. In North America its post-World War II invention is credited to Canadian Welland Phipps, potentially inspired by the Goodyear Tire & Rubber Company's pre-World War II development of their own, similar low-pressure "airwheel" as a complete wheel-rim and tire set — said to be of the "Musselman" type from , for its orig ...

AC3D
AC3D is a 3D design program which has been available since 1994. The software is used by designers for modeling 3D graphics for games and simulations - most notably it is used by the scenery creators at Laminar Research on the X-Plane (simulator). The .ac format has also been used in FlightGear for scenery objects and aircraft models. History Initially developed on the Amiga, the code was then ported to Silicon Graphics workstations which used the GL graphics library. At that time, the user interface was implemented using X11/ Motif. A Linux port was released onto the internet in 1994 (the GL graphics were replaced with OpenGL). A Microsoft Windows port followed when the X11 interface was dropped in favor of the portable Tcl/Tk scripting library. In 2002, Inivis Limited purchased the full intellectual property rights to AC3D and continues to develop and market the software. They decided to keep the name AC3D for the software. In 2005, a Mac OS X version of AC3D was release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Air Traffic Simulation Network
Virtual Air Traffic Simulation Network (VATSIM) is a nonprofit organization that operates an online flight-simulation network noted for its active membership and realism. Users are able to fly aircraft as a pilot, or direct traffic as an air traffic controller in what has been described as a close approximation of real-life aviation procedures. Overview Communications between pilots and controllers are carried out using integrated VoIP or in-game text messages. Users are required to use custom software, designated as approved clients, in order to connect to the simulation. The main organs of the network consist of the Board of Governors, three of whom are responsible for one of the three geographic regions—namely, the Europe, the Middle East and Africa region, the Asia-Pacific region, and the Americas region, referred to as VATEMEA, VATAPAC and VATAMAS respectively. These regions are further subdivided into divisions, some of which further divide into virtual ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blended Wing Body
A blended wing body (BWB), also known as blended body or hybrid wing body (HWB), is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line.Crane, Dale. ''Dictionary of Aeronautical Terms, third edition''. Newcastle, Washington: Aviation Supplies & Academics, 1997. . p. 224. This contrasts with a flying wing, which has no distinct fuselage, and a lifting body, which has no distinct wings. A BWB design may or may not be tailless. The main advantage of the BWB is to reduce wetted area and the accompanying form drag associated with a conventional wing-body junction. It may also be given a wide airfoil-shaped body, allowing the entire craft to generate lift and thus reducing the size and drag of the wings. The BWB configuration is used for both aircraft and underwater gliders. History In the early 1920s Nicolas Woyevo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingco Atlantica
Atlantica is a blended wing body aircraft being developed by Wingco, an aircraft manufacturer. Wingco's website states that the aircraft is based on technology developed before World War II. The aircraft features five seats and a top speed of . The aircraft is unique in that it is made from five different sections welded together. Accident During testing at Orlando Melbourne International Airport in Florida in January 2003, a prototype aircraft was involved in an accident. The pilot told authorities that he had been carrying out a high speed taxi to test the aircraft, and had not intended to become airborne, however the plane lifted off the tarmac and impacted with it again seconds later. The pilot suffered minor injuries in the accident. A report by the NTSB (National Transportation Safety Board) found that: During the high speed taxi, the pilot raised the nose of the airplane and it became airborne. The airplane climbed with a high angle of attack to approximately 100 fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CarterCopter
The CarterCopter is an experimental compound autogyro developed by Carter Aviation Technologies in the United States to demonstrate slowed rotor technology. On 17 June 2005, the CarterCopter became the first rotorcraft to achieve mu-1 (μ=1), an equal ratio of airspeed to rotor tip speed, but crashed on the next flight and has been inoperable since.CarterCopter Advances Towards Mu>1.0 (Part 1) Concept The CarterCopter concept is a gyrocopter with an unusually stiff, relatively heavy rotor, supplemented with conventional wings. At low speed, the vehicle flies as a gyrocopter, and can pre-spin the rotor for a vertical takeoff and very brief hover (about 5 seconds),Henry Farkas and Claudius Klimt''SW Aviator Magazine''. Retrieved: 1 August 2012. and can land more or less vertically. Several technical challenges make flying a slow rotor difficult, but rotor stability is achieved through the combination of the rotor tip weights' location ahead of the blade center line (forward center o ...

Lookup Table
In computer science, a lookup table (LUT) is an array that replaces runtime computation with a simpler array indexing operation. The process is termed as "direct addressing" and LUTs differ from hash tables in a way that, to retrieve a value v with key k, a hash table would store the value v in the slot h(k) where h is a hash function i.e. k is used to compute the slot, while in the case of LUT, the value v is stored in slot k, thus directly addressable. The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input/output operation. The tables may be precalculated and stored in static program storage, calculated (or "pre-fetched") as part of a program's initialization phase ( memoization), or even stored in hardware in application-specific platforms. Lookup tables are also used extensively to validate input values by matching against a list of valid (or invalid) items in an array and ...

Empirical Evidence
Empirical evidence for a proposition is evidence, i.e. what supports or counters this proposition, that is constituted by or accessible to sense experience or experimental procedure. Empirical evidence is of central importance to the sciences and plays a role in various other fields, like epistemology and law. There is no general agreement on how the terms ''evidence'' and ''empirical'' are to be defined. Often different fields work with quite different conceptions. In epistemology, evidence is what justifies beliefs or what determines whether holding a certain belief is rational. This is only possible if the evidence is possessed by the person, which has prompted various epistemologists to conceive evidence as private mental states like experiences or other beliefs. In philosophy of science, on the other hand, evidence is understood as that which '' confirms'' or ''disconfirms'' scientific hypotheses and arbitrates between competing theories. For this role, it is important that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
