Air Transat Flight 236
Air Transat Flight 236 was a transatlantic flight bound for Lisbon, Portugal, from Toronto, Canada, that lost all engine power while flying over the Atlantic Ocean on August 24, 2001. The Airbus A330 ran out of fuel because of a fuel leak caused by improper maintenance. Captain Robert Piché, 48, and First Officer Dirk DeJager, 28, glided the plane to a successful emergency landing in the Azores, saving the lives of all 306 people (293 passengers and 13 crew) on board. Most of the passengers on the flight were Canadians visiting Europe or Portuguese expatriates returning to visit family in Portugal. This was also the longest passenger aircraft glide without engines, gliding for nearly . Following this unusual aviation accident, this aircraft was nicknamed the "Azores Glider". Aircraft The aircraft involved was an Airbus A330-243 registered as C-GITS. The aircraft was just over two years old and was equipped with two Rolls-Royce Trent 772B-60 engines.

Fuel Exhaustion
In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading to loss of power or engine stoppage. There is still fuel in the tank(s), but it is unable to get to the engine(s) in sufficient quantity. By contrast, fuel exhaustion (also called ''fuel depletion'') is an occurrence in which the vehicle in question becomes completely devoid of usable fuel, with results similar to those of fuel starvation. All engine-powered modes of transport can be affected by fuel starvation, although the problem is most serious for aircraft in flight. Ships are affected to the extent that without propulsion they cannot maneuver to avoid collisions or beaching. On aircraft, fuel starvation is often the result of incorrect fuel management, for example by selecting to feed the engine from an emp ...

List Of Airline Flights That Required Gliding
Airplane gliding occurs when all the engines of an aircraft shut down, but the wings are still functional and can be used for a controlled descent. This is a very rare condition in multi-engine airliners, though it is the obvious result when a single-engine airplane experiences engine failure. The most common cause of engine shutdown is fuel exhaustion or fuel starvation, but there have been other cases in aviation history of multiple engine failure due to bird strikes, flying through volcano ash, ingesting debris, and various forms of damage due to water (hail, ice or overwhelming rain). Below is a list of commercial airline flights that were forced to glide at some point while in the air.

Mayday (distress Signal)
Mayday is an emergency procedure word used internationally as a distress signal in Voice procedure, voice-procedure Radio, radio communications. It is used to signal a life-threatening emergency primarily by aviators and mariners, but in some countries local organizations such as firefighters, police forces, and transportation organizations also use the term. Convention requires the word be repeated three times in a row during the initial emergency declaration ("Mayday mayday mayday"). History The "mayday" procedure word was conceived as a distress call in the early 1920s by Frederick Stanley Mockford, officer-in-charge of radio at Croydon Airport, England. He had been asked to think of a word that would indicate distress and would easily be understood by all pilots and ground staff in an emergency. Since much of the air traffic at the time was between Croydon and Le Bourget Airport in Paris, he proposed the term "mayday", the phonetic equivalent of the French (a short form of ...

Flameout
In aviation, a flameout (or flame-out) is the run-down of a jet engine or other turbine engine due to the extinguishment of the flame in its combustor. The loss of flame can have a variety of causes, such as fuel starvation, excessive altitude, compressor stall, foreign object damage deriving from birds, hail, or volcanic ash, severe precipitation, mechanical failure, or very low ambient temperatures. Engine control Early jet engines were prone to flameout following disturbances of inlet airflow, or sudden or inappropriate thrust lever movements, which resulted in incorrect air-fuel ratios in the combustion chamber. Modern engines are much more robust in this respect, and are often digitally controlled, which allows for significantly more effective control of all engine parameters to prevent flameouts and even initiate an automatic restart if a flameout occurs. Flameouts occur most frequently at intermediate or low power settings such as in cruise and descent. To prevent a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Maria Oceanic Control
Santa Maria Oceanic Control is an air traffic control area over the Atlantic Ocean. Santa Maria Flight information region, also known as FIR, is Europe's largest and one of the largest in the world. Covering the southeastern part of the North Atlantic Ocean, Santa Maria FIR is on the key routes of most of the flights from Europe to Central and South America. In the middle of the FIR, the nine Azores The Azores ( , , ; , ), officially the Autonomous Region of the Azores (), is one of the two autonomous regions of Portugal (along with Madeira). It is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atl ... islands attract thousands of tourists and further increase the traffic in Santa Maria FIR. The airports are also known for saving a considerable amount of money and lives by serving as an en-route alternate airport for many transatlantic flights.

Lajes Air Base
Lajes Field or Lajes Air Base (; ), officially designated Air Base No. 4 (''Base Aérea N.º 4'', BA4) , is a multi-use airfield near Lajes and northeast of Angra do Heroísmo on Terceira Island in the Azores, Portugal. It is home to the Portuguese Air Force ''Base Aérea N.º 4'' and Azores Air Zone Command (), a United States Air Force detachment unit (operated by the 65th Air Base Group of United States Air Forces in Europe - Air Forces Africa), and a regional air passenger terminal. Located about east of New York City and about west of Lisbon, Portugal; the base sits in a strategic location midway between North America and Europe in the north Atlantic Ocean. History The origin of the Lajes Field dates back to 1928, when Portuguese Army Lieutenant Colonel Eduardo Gomes da Silva wrote a report on the possible construction of an airfield in the plainland of Lajes, for that branch's aviation service (). However, the location of Achada on the center of the island was chos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thrust
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called thrust. Force, and thus thrust, is measured using the International System of Units (SI) in newtons (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 meter per second per second. In mechanical engineering, force orthogonal to the main load (such as in parallel helical gears) is referred to as static thrust. Examples A fixed-wing aircraft propulsion system generates forward thrust when air is pushed in the direction opposite to flight. This can be done by different means such as the spinning blades of a propeller, the propelling jet of a jet engine, or by ejecting hot gases f ...

Airbus A330-243
The Airbus A330 is a wide-body airliner developed and produced by Airbus. Airbus began developing larger A300 derivatives in the mid–1970s, giving rise to the A330 twinjet as well as the Airbus A340 quadjet, and launched both designs along with their first orders in June 1987. The A330-300, the first variant, took its maiden flight in November 1992 and entered service with Air Inter in January 1994. The A330-200, a shortened longer-range variant, followed in 1998 with Canada 3000 as the launch operator. The A330 shares many underpinnings with the airframe of the early A340 variants, most notably the same wing components, and by extension the same structure. However, the A330 has two main landing gear legs instead of three, lower weights, and slightly different fuselage lengths. Both airliners have fly-by-wire controls as well as a similar glass cockpit to increase the commonality. The A330 was Airbus's first airliner to offer a choice of three engines: the General Electric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crew
A crew is a body or a group of people who work at a common activity, generally in a structured or hierarchy, hierarchical organization. A location in which a crew works is called a crewyard or a workyard. The word has nautical resonances: the tasks involved in operating a ship, particularly a sailing ship, providing numerous specialities within a ship's crew, often organised with a chain of command. Traditional nautical usage strongly distinguishes Commissioned officer, officers from crew, though the two groups combined form the ship's company. Members of a crew are often referred to by the titles ''crewmate'', ''crewman'' or ''crew-member.'' ''Crew'' also refers to the sport of rowing (sport), rowing, where teams row competitively in racing shells.
