Business Jet
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people. Business jets may be adapted for other roles, such as the evacuation of casualties or express parcel deliveries, and some are used by public bodies, government officials or the armed forces. History Early developments The first small jet-powered civil aircraft was the Morane-Saulnier MS.760 Paris, developed privately in the early 1950s from the Morane-Saulnier MS.755 Fleuret, MS.755 Fleuret two-seat jet trainer. First flown in 1954, the MS.760 Paris differs from subsequent business jets in having only four seats arranged in two rows without a center aisle, similar to a light aircraft, under a large sliding canopy (aircraft), canopy similar to that of a fighter aircraft, fighter. A U.S. type certificate was awarded in July 1958, but commercial sales were limited, with most examples going to the military; an improved civil version similar to a modern very light jet, with a ...

Lufthansa Technik
Lufthansa Technik AG ('Lufthansa Engineering', often referred to simply as “LHT”) provides worldwide maintenance, repair, and overhaul (MRO) services for aircraft, engines, and components. It is a subsidiary of the Lufthansa Group. Headquartered at Hamburg Airport, its other important German sites are in Frankfurt Airport and Munich Airport. In greater Europe, it has major base maintenance facilities in Malta, Budapest, Hungary, and Bulgaria. Overseas, it has sites located in Puerto Rico, the Philippines, and China. History The origins of Lufthansa Technik can be traced back to 1951, predating that of its parent company, the German flag carrier Lufthansa. West German officials decided that, in advance of forming a new national airline, the establishment of a new maintenance base at Hamburg Airport should be undertaken as a preparatory step. Various new hangars, workshops, and storage facilities were established, enabling a fully range of services could be provided from the ons ...

True Airspeed
The true airspeed (TAS; also KTAS, for ''knots true airspeed'') of an aircraft is the speed of the aircraft relative to the air mass through which it is flying. The true airspeed is important information for accurate navigation of an aircraft. Traditionally it is measured using an analogue TAS indicator, but as the Global Positioning System has become available for civilian use, the importance of such air-measuring instruments has decreased. Since ''indicated'', as opposed to ''true'', airspeed is a better indicator of margin above the stall, true airspeed is not used for controlling the aircraft; for these purposes the indicated airspeed – IAS or KIAS (knots indicated airspeed) – is used. However, since indicated airspeed only shows true speed through the air at standard sea level pressure and temperature, a TAS meter is necessary for navigation purposes at cruising altitude in less dense air. The IAS meter reads very nearly the TAS at lower altitude and at lower spe ...

Garrett TFE731
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace. Since the engine was introduced in 1972, over 11,000 engines have been built, flying over 100 million flight-hours. Development The TFE731 was based on the core of the TSCP700, which was specifically developed for use as the auxiliary power unit (APU) on the McDonnell Douglas DC-10. The design featured two important factors: low fuel consumption, and low noise profiles that met the newly established U.S. noise abatement regulations. The first test run of the TFE731 occurred in 1970 at Garrett's plant in Torrance, California. The first production model, the TFE731-2, began rolling off the assembly line in August, 1972, and was used on the Learjet 35/36 and Dassault Falcon 10, both of which entered production in 1 ...

Cabin Pressurization
Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. For aircraft, this air is usually bled off from the gas turbine engines at the compressor stage, and for spacecraft, it is carried in high-pressure, often cryogenic, tanks. The air is cooled, humidified, and mixed with recirculated air if necessary before it is distributed to the cabin by one or more environmental control systems. The cabin pressure is regulated by the outflow valve. While the first experimental pressurization systems saw use during the 1920s and 1930s, it was not until 1940 that a commercial aircraft would enter service with a pressurized cabin, when the Boeing 307 Stratoliner joined the Transcontinental & Western Air and Pan American Airways fleets. The practice would become widespread a decade later, particularly with the introduction of the ...

FAR Part 23
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs comprise Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, man-made structure heights, obstruction lighting and marking, model rocket launches, commercial space operations, model aircraft operations, Unmanned Aircraft Systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk. FAR vs. 14 CFR Since 1958, these rules have typically been referred to as "FARs", short for Federal Aviation Regulations. However, another set of regulations (Title 48) is titled "Federal Acquisitions Regulations", and this has led to confu ...

Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115  V AC voltage at 400  Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, World War 1, Supermarine Nighthawk, an anti-Zeppelin night fighter.Andrews and Morgan 1987, p. 21. During World War II, a number of large Ameri ...

Aviation Week
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ...
