Widerøe Flight 710
Widerøe Flight 710, commonly known as the Torghatten Accident ( no, Torghatten-ulykken), was a controlled flight into terrain into the mountain of Torghatten in Brønnøy, Norway. The Widerøe-operated de Havilland Canada Dash 7 crashed on 6 May 1988 at 20:29:30 during approach to Brønnøysund Airport, Brønnøy. All thirty-six people on board LN-WFN were killed; the crash remains the deadliest accident involving the Dash 7 and the deadliest in Northern Norway. The direct cause of the accident was that the aircraft had descended from 500 meters to 170 meters (1,500–550 ft) at instead of from the airport. An investigation found several shortcomings in the airline's operating procedures, in particular lack of proper cockpit communication and mutual control of the descent and approach plans. This was in part caused by the airline electing to not follow the sterile cockpit rule and that a passenger was sitting in a cockpit jump seat during the flight. Th ...

Jump Seat
In aviation, a jump seat or jumpseat is an auxiliary seat for individuals—other than normal passengers—who are not operating the aircraft. In general, the term 'jump seat' can also refer to a seat in any type of vehicle which can fold up out of the way; vehicles include carriages, automobiles, vans, buses, fire tenders, and taxicabs. The term originated in the United States c. 1860 for a movable carriage seat. In land vehicles Jump seats originated in horse-drawn carriages. Jump seats were features of many early automobiles, but are now rare, present mainly in limousines. They are also used in UPS delivery vans. Some pickup trucks also employ jump seats, particularly those with an extended cab which don't have room for full rear passenger seats. These seats are often mounted against the side of the cab interior and fold up when not in use. In airplanes In airplanes, jump seats—which are officially termed ''auxiliary crew stations''—can be located in the flight de ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and re ...

Distance Measuring Equipment
In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ground station is required. An interrogator (airborne) initiates an exchange by transmitting a pulse pair, on an assigned 'channel', to the transponder ground station. The channel assignment specifies the carrier frequency and the spacing between the pulses. After a known delay, the transponder replies by transmitting a pulse pair on a frequency that is offset from the interrogation frequency by 63 MHz and having specified separation.''Annex 10 to the Convention on International Civil Aviation, Volume I – Radio Navigation Aids''; International Civil Aviation Organization; International Standards and Recommended Practices. DME systems are used worldwide, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VHF Omnidirectional Radio Range
Very high frequency omnirange station (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine its position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons. It uses frequencies in the very high frequency (VHF) band from 108.00 to 117.95 MHz. Developed in the United States beginning in 1937 and deployed by 1946, VOR became the standard air navigational system in the world,VOR VHF omnidirectional Range , Aviation Tutorial – Radio Navaids, kispo.net used by both commercial and general aviation, until supplanted by satellite navigation systems such as in th ...

Torghatten 1
Torghatten is a granite dome on the island of Torget in Brønnøy Municipality in Nordland county, Norway. It is known for its characteristic hole, or natural tunnel, through its center. It is possible to walk up to the tunnel on a well-prepared path, and through it on a natural path. On 6 May 1988, Widerøe Flight 710 from Namsos to Brønnøysund crashed into the side of the mountain, and all 36 passengers and crew died. Tunnel According to legend, the hole was made by the troll ''Hestmannen'' while he was chasing the beautiful girl '' Lekamøya''. As the troll realized he would not get the girl, he released an arrow to kill her, but the troll-king of Sømna threw his hat into the arrow's path to save her. The hat turned into the mountain with a hole in the middle. The tunnel is long, wide, and high. It was formed during the Scandinavian ice age. Ice and water eroded the looser rocks, while the harder ones in the mountain top have resisted erosion. See also * Monte F ...

Aerodrome Flight Information Service
A flight information service (FIS) is a form of air traffic service which is available to any aircraft within a flight information region (FIR), as agreed internationally by ICAO. It is defined as information pertinent to the safe and efficient conduct of flight, and includes information on other potentially conflicting traffic, possibly derived from radar, but stopping short of providing positive separation from that traffic. Flight Information also includes: *Meteorological information *Information on aerodromes *Information on possible hazards to flight FIS shall be provided to all aircraft which are provided with any air traffic control (ATC) service or are otherwise known to air traffic service units. All air traffic service units will provide an FIS to any aircraft, in addition to their other tasks. Aerodrome Flight Information Service In most countries, an Aerodrome Flight Information Service (AFIS) is provided at airfields where, despite not being busy enough for full a ...

Pilot Licensing And Certification
Pilot licensing or certification refers to permits for operating aircraft. Flight crew licences are regulated by ICAO Annex 1 and issued by the civil aviation authority of each country. CAA’s have to establish that the holder has met a specific set of knowledge and experience before issuing the licence. The licence, with added ratings, allows a pilot to fly aircraft registered in the licence issuing state. The ICAO ''Annex 1 - Personnel Licensing'' acts as the international minimum standards for licensing, however states can deviate from these standards by notifying ICAO about the changes. This, for instance, is why there are certain differences regarding licensing between EASA in Europe and the FAA in the USA. Regulation by country In the United States, pilot certification is regulated by the Federal Aviation Administration (FAA), a branch of the U.S. Department of Transportation (DOT). A pilot is certified under the authority of Parts 61 and 141 of Title 14 of the Cod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
