Cathay Pacific Flight 780
Cathay Pacific Flight 780 was a flight from Juanda International Airport in Surabaya, Indonesia to Hong Kong International Airport on 13 April 2010. On board were 309 passengers and a crew of 13. As Flight 780 neared Hong Kong, the crew were unable to change the thrust output of the engines. The aircraft, an Airbus A330-342, landed at almost twice the speed of a normal landing, suffering minor damage. The 57 passengers who sustained injuries were hurt in the ensuing slide evacuation; one of them received serious injuries. The cause of the accident was contamination of the fuel taken on board at Surabaya, which gradually damaged both engines of the aircraft. The flight's two Australian pilots, Captain Malcolm Waters and First Officer David Hayhoe, who safely landed the aircraft despite the extraordinary challenge, have been compared to pilots Chesley Sullenberger and Jeffrey Skiles of US Airways Flight 1549 the previous year (January 2009). In March 2014, the two Flight 780 pil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Failure
A turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can fail, like ground-based turbines used in power plants or combined diesel and gas vessels and vehicles. Reliability Turbine engines in use on today's turbine-powered aircraft are very reliable. Engines operate efficiently with regularly scheduled inspections and maintenance. These units can have lives ranging in the thousands of hours of operation. However, engine malfunctions or failures occasionally occur that require an engine to be shut down in flight. Since multi-engine airplanes are designed to fly with one engine inoperative and flight crews are trained to fly with one engine inoperative, the in-flight shutdown of an engine typically does not constitute a serious safety of flight issue. The Federal Aviation Administration (FAA) was quoted as stating turbine engines have a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ted Stevens Anchorage International Airport
Ted Stevens Anchorage International Airport is a major airport in the U.S. state of Alaska, located southwest of downtown Anchorage. The airport is named for Ted Stevens, a U.S. senator from Alaska in office from 1968 to 2009. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a medium-hub primary commercial service facility. History Built in 1951, the airport was served in the 1950s by Alaska Airlines, Northwest Orient, Pacific Northern Airlines and Reeve Aleutian Airways, using aircraft ranging from Douglas DC-3s to Boeing 377s, and was also a refueling stop for Canadian Pacific Air Lines service to the Far East (one such aircraft being involved in a 1951 disappearance). From 1955 to 2011, the eastern end of the airport's southernmost runway connected to the Kulis Air National Guard Base. By the mid-1980s the airport's nickname was "Crossroads of the World". Anchorage was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Accidents Investigation Branch
The Air Accidents Investigation Branch (AAIB) investigates civil aircraft accidents and serious incidents within the United Kingdom, its overseas territories and crown dependencies. It is also the Space Accident Investigation Authority (SAIA) for the United Kingdom. The AAIB is a branch of the Department for Transport and is based in the grounds of Farnborough Airport, Rushmoor, Hampshire. History Aviation accident investigation in the United Kingdom started in 1912, when the Royal Aero Club published a report into a fatal accident at Brooklands Aerodrome, Surrey. The AAIB was established in 1915 as the Accidents Investigation Branch (AIB) of the Royal Flying Corps (RFC). Captain G B Cockburn was appointed "Inspector of Accidents" for the RFC, reporting directly to the Director General of Military Aeronautics in the War Office. After the First World War, the Department of Civil Aviation was set up in the Air Ministry and the AIB became part of that department with a remit ...

Emergency Evacuation
Emergency evacuation is the urgent immediate egress or escape of people away from an area that contains an imminent threat, an ongoing threat or a hazard to lives or property. Examples range from the small-scale evacuation of a building due to a storm or fire to the large-scale evacuation of a city because of a flood, bombardment or approaching weather system, especially a tropical cyclone. In situations involving hazardous materials or possible contamination, evacuees may be decontaminated prior to being transported out of the contaminated area. Evacuation planning is an important aspect of business management of which emergency evacuation forms a part. Reasons for evacuation Evacuations may be carried out before, during, or after disasters such as: * Natural disasters ** Eruptions of volcanoes ** Tropical cyclones ** Floods ** Earthquakes ** Tsunamis ** Wildfires/Bushfires * Industrial accidents ** Chemical spill ** Nuclear accident * Transport ** Road accidents ** Tr ...

Airbreathing Jet Engine
An airbreathing jet engine (or ''ducted jet engine'') is a jet engine that ejects a propelling (reaction) jet of hot exhaust gases after first taking in atmospheric air, followed by compression, heating and expansion back to atmospheric pressure through a nozzle. Alternatively the reaction jet may include a cold jet of ducted bypass air which has been compressed by a fan before returning to atmospheric pressure through an additional nozzle. These engines are gas turbine engines. Engines using only ram for the compression process, and no turbomachinery, are the ramjet and pulsejet. All practical airbreathing jet engines heat the air by burning fuel. Alternatively a heat exchanger may be used ( nuclear-powered jet engine). Most modern jet engines are turbofans. They replaced turbojets as they use less fuel. Background The original air-breathing gas turbine jet engine was the turbojet. It was a concept brought to life by two engineers, Frank Whittle in England UK and Hans von Oha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayday (distress Signal)
Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure 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") to prevent it being mistaken for some similar-sounding phrase under noisy conditions, and to distinguish an ''actual'' mayday call from a message ''about'' a mayday call. 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 t ...

Descent (aeronautics)
In aeronautics, a descent is any time period during air travel where an aircraft decreases altitude, and is the opposite of an ''ascent'' or '' climb''. Descents are part of normal procedures, but also occur during emergencies, such as rapid or explosive decompression, forcing an emergency descent to below and preferably below , respectively the maximum temporary safe altitude for an unpressurized aircraft and the maximum safe altitude for extended duration. An example of explosive decompression is Aloha Airlines Flight 243. Involuntary descent might occur from a decrease in power, decreased lift (wing icing), an increase in drag, or flying in an air mass moving downward, such as a terrain induced downdraft, near a thunderstorm, in a downburst, or microburst. Normal descents Intentional descents might be undertaken to land, avoid other air traffic or poor flight conditions (turbulence, icing conditions, or bad weather), clouds (particularly under visual flight rules), to se ...

Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advisories'' (known as ''flight infor ...

Pan-pan
The radiotelephony message PAN-PAN is the international standard urgency signal that someone aboard a boat, ship, aircraft, or other vehicle uses to declare that they have a situation that is urgent, but for the time being, does not pose an immediate danger to anyone's life or to the vessel itself. This is referred to as a state of "urgency". This is distinct from a mayday call (distress signal), which means that there is imminent danger to life or to the continued viability of the vessel itself. Radioing "pan-pan" informs potential rescuers (including emergency services and other craft in the area) that an urgent problem exists, whereas "mayday" calls on them to drop all other activities and immediately begin a rescue. The exact representation of PAN in Morse code is the urgency signal XXX, which was first defined by the International Radiotelegraph Convention of 1927. Etymology As with "mayday" (from ''venez m'aider'', "come help me"), the urgency signal pan-pan derives from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressor Stall
A compressor stall is a local disruption of the airflow in the compressor of a gas turbine or turbocharger. A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge. The severity of the phenomenon ranges from a momentary power drop barely registered by the engine instruments to a complete loss of compression in case of a surge, requiring adjustments in the fuel flow to recover normal operation. Compressor stall was a common problem on early jet engines with simple aerodynamics and manual or mechanical fuel control units, but has been virtually eliminated by better design and the use of hydromechanical and electronic control systems such as Full Authority Digital Engine Control. Modern compressors are carefully designed and controlled to avoid or limit stall within an engine's operating range. Types There are two types of compressor stall: Rotating stall Rotating stall is a local disruption of airflow within the com ...
