Atlantic Airways Flight 670
Atlantic Airways Flight 670 was a crash following a runway overrun of a British Aerospace 146, British Aerospace 146-200A at 07:32 on 10 October 2006 at Stord Airport, Sørstokken, Norway. The aircraft's spoiler (aeronautics), spoilers failed to deploy, causing inefficient braking. The Atlantic Airways aircraft fell down the steep cliff at the end of the runway at slow speed and burst into flames, killing four of sixteen people on board. The flight was chartered by Aker Kværner from Stavanger Airport, Sola via Sørstokken to transport its employees from there and Stord to Molde Airport, Årø. An investigation was carried out by the Accident Investigation Board Norway (AIBN). It was not able to find the underlying cause of the spoiler malfunction. However, it found that, when the captain selected the emergency braking, the anti-lock braking system was disabled. This selection caused the brakes to completely lock, resulting in Aquaplaning#Reverted rubber, reverted rubber hydroplan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquaplaning
Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs. If it occurs to all wheels simultaneously, the vehicle becomes, in effect, an uncontrolled sled. Aquaplaning is a different phenomenon from when water on the surface of the roadway merely acts as a lubricant. Traction is diminished on wet pavement even when aquaplaning is not occurring. Causes Every vehicle function that changes direction or speed relies on friction between the tires and the road surface. The grooves of a rubber tire are designed to disperse water from beneath the tire, providing high friction even in wet conditions. Aquaplaning occurs when a tire encounters more water than it can dissipate. Water pressure in front of the wheel forces a wedge of water under the leading edge of the tire, cau ...

First Officer (aeronautics)
In aviation, the first officer (FO), also called co-pilot, is the pilot who is second-in-command of the aircraft to the captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft. Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot normally designated the "pilot flying" and the other the "pilot not flying", or "pilot monitoring", for each flight. Even when the first officer is the flying pilot, however, the captain remains ultimately responsible for the aircraft, its passengers, and the crew. In typical day-to-day operations, the essential job tasks remain fairly equal. Traditionally, the first officer sits on the right-hand side of a fixed-wing aircraft ("right seat") and the left-hand side of a helicopter (the reason for this difference is related to, in many cases, the pilot flying being unable to release the right hand from the cyclic contr ...

Cabinet Of The Faroe Islands
The Cabinet of the Faroe Islands (Faroese: Føroya Landsstýri) has been the chief executive body and the government of the Faroe Islands since the islands became self-governing in 1948. The cabinet is led by the prime minister (''løgmaður''). There are around seven members of the Cabinet, known as "ministers" (landsstýrismaður or landsstýriskvinna), all of whom are also heads of specific government ministries. The ministers are appointed by the prime minister. The Faroese government currently consists of seven ministers including the prime minister.

Faroe Islands
The Faroe Islands ( ), or simply the Faroes ( fo, Føroyar ; da, Færøerne ), are a North Atlantic island group and an autonomous territory of the Kingdom of Denmark. They are located north-northwest of Scotland, and about halfway between Norway ( away) and Iceland ( away). The islands form part of the Kingdom of Denmark, along with mainland Denmark and Greenland. The islands have a total area of about with a population of 54,000 as of June 2022. The terrain is rugged, and the subpolar oceanic climate (Cfc) is windy, wet, cloudy, and cool. Temperatures for such a northerly climate are moderated by the Gulf Stream, averaging above freezing throughout the year, and hovering around in summer and 5 °C (41 °F) in winter. The northerly latitude also results in perpetual civil twilight during summer nights and very short winter days. Between 1035 and 1814, the Faroe Islands were part of the Kingdom of Norway, which was in a personal union with Denmark from 1 ...

Atlantic Airways Flight 670 Cliffs
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atlantic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust Reversal
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines. There have been accidents involving thrust reversal systems, including fatal ones. Reverse thrust is also available on many propeller-driven aircraft through reversing the controllable-pitch propellers to a negative angle. The equivalent concept for a ship is called astern propulsion. Principle and uses A landing roll consists of touchdown, bringing the aircraft to taxi speed, and eventually to a complete stop. However, most commercial jet engines continue to produce thrust in the forward direction, even when idle, actin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Brake (aeronautics)
In aeronautics, air brakes or speed brakes are a type of flight control surface used on an aircraft to increase the drag on the aircraft. Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, whereas spoilers reduce the lift-to-drag ratio and require a higher angle of attack to maintain lift, resulting in a higher stall speed. Introduction An air brake is a part of an aircraft. When extended into the airstream, it causes an increase in the drag on the aircraft. When not in use, it conforms to the local streamlined profile of the aircraft in order to help minimise the drag. History In the early decades of powered flight, air brakes were flaps mounted on the wings. They were manually controlled by a lever in the cockpit, and mechanical linkages to the air brake. An early type of air brake, developed in 1931, was fitted to the aircraft wing support struts. In 1936, Hans Jacobs, who headed Nazi Germany's ...

Geared Turbofan
The geared turbofan is a type of turbofan aircraft engine, with a gearbox between the fan and the low pressure shaft to spin each at optimum angular velocities. Technology In a conventional turbofan, a single shaft (the "low-pressure" or LP shaft) connects the fan, the low-pressure compressor and the low-pressure turbine (a second concentric shaft connects the high-pressure compressor and high-pressure turbine). In this configuration, the maximum tip speed for the larger radius fan limits the rotational speed for the LP shaft and thus the LP compressor and turbine. At high bypass ratios (and thus high radius ratios) the tip speeds of the LP turbine and LP compressor must be relatively low, which means extra compressor and turbine stages are required to keep the average stage loadings and, therefore, overall component efficiencies to an acceptable level. In a geared turbofan, a planetary reduction gearbox between the fan and the LP shaft allows the latter to run at a higher ro ...

Avco Lycoming ALF502R-5
The Lycoming ALF 502/LF 507 (now:Honeywell ALF 502/LF 507) is a geared turbofan engine produced by Lycoming Engines, AlliedSignal, and then Honeywell Aerospace. Development In mid-1970, Avco Lycoming was advertising two Lycoming T55-derived engines, an LTC4B-12 turboprop and an ALF 502A turbofan, as possible powerplants for the U.S. Air Force's A-X close air support aircraft program. Northrop Corporation signed a contract with Avco Lycoming to use the ALF 502A for its entry into the A-X competition, the Northrop YA-9, in January 1971. The engine was given a United States military aircraft engine designation of YF102-LD-100. Six YF102 engines were built for the YA-9. The thrust engines powered the A-9A prototypes for seven months of flight tests in 1972, recording 238 flights and 652 flight hours. These engines were later reused in the C-8A Quiet Short-Haul Research Aircraft (QSRA). The commercial ALF 502D engine was developed from the military YF102 in 1971. Its derated engi ...
