Birgenair Flight 301
Birgenair Flight 301 was a flight chartered by Turkish-managed Birgenair partner Alas Nacionales from San Felipe de Puerto Plata, Puerto Plata in the Dominican Republic to Frankfurt, Germany, via Gander, Newfoundland and Labrador, Gander, Canada, and Berlin, Germany. On 6 February 1996, the Boeing 757-200 operating the route crashed shortly after take-off from Puerto Plata's Gregorio Luperón International Airport, killing all 189 people on board. The cause was pilot error after receiving incorrect airspeed information from one of the pitot tubes, which investigators believe was blocked by a Sphecidae, wasp nest built inside it. The aircraft had been sitting unused for 20 days, and without Remove before flight, pitot tube covers in place for the two days preceding the crash. Flight 301 is tied with American Airlines Flight 77 as the deadliest aviation incident involving a Boeing 757, having a total of 189 fatalities. Furthermore, Flight 301 is the deadliest aviation accident eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitot Tube
A pitot tube ( ; also pitot probe) measures fluid flow velocity. It was invented by French engineer Henri Pitot during his work with aqueducts and published in 1732, and modified to its modern form in 1858 by Henry Darcy. It is widely used to determine the airspeed of aircraft; the water speed of boats; and the flow velocity of liquids, air, and gases in industry. Theory of operation The basic pitot tube consists of a tube pointing directly into the oncoming fluid flow. Pressure in the tube can be measured as the moving fluid cannot escape and stagnates. This pressure is the stagnation pressure of the fluid, also known as the total pressure or (particularly in aviation) the pitot pressure. The measured stagnation pressure cannot just by itself be used to determine the fluid flow velocity (airspeed in aviation) directly. However, with a measured static pressure as well it can be determined by the use of Bernoulli's equation which states: :Stagnation pressure = static pr ...

In-flight Crew Relief
In-flight crew relief (commonly referred in noun form as the relief aircrew, relief flight crew, or just relief crew), is a term used in commercial aviation when referring to the members of an aircrew intended to temporarily relieve active crew members of their duties during the course of a flight. The term and its role are almost exclusively applied to the secondary pilots of an aircrew, commonly referred to as relief pilots, that relieve the primary and active captain and/or first officer (co-pilot) in command of an aircraft to provide prolonged breaks for rest or sleep opportunities. Usage In-flight crew relief is generally required for flights that are determined to be long haul or "ultra-long haul" on aircraft commercially operated (airline operated). In certain places such as the United States, flights will be given these classifications and equipped with relief crews when around or exceeding 8–12 hours domestically or internationally. Operators of these flights prototyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Officer (aviation)
In aviation, the first officer (FO), also called co-pilot, is a Aircraft pilot, pilot in addition to the Pilot in command, captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft. Requirement Historically, large aircraft had several personnel on the flight deck, such as a Air navigator, navigator, a flight engineer, and a dedicated radio operator. Improvements in automation and reliability have reduced this to two. Many aircraft require a minimum of two flight crew. The minimum crew requirement will be stated in the aircraft manuals by the manufacturer. In the European Union, all turbo-propeller aeroplanes with a maximum approved passenger seating configuration of more than nine and all turbo-jet aeroplanes require two pilots.EU OPS (965) Subpart N, Ops 1.940 Composition of flight crew Role Control of the aircraft is normally shared equally between the first officer and the captain, with one pilot ...

Pilot In Command
The pilot in command (PIC) of an aircraft is the person aboard an aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three- pilot aircrew, or "pilot" if there is only one certificated and qualified pilot at the controls of an aircraft. The PIC must be legally certificated (or otherwise authorized) to operate the aircraft for the specific flight and flight conditions, but need not be actually manipulating the controls at any given moment. The PIC is the person legally in charge of the aircraft and its flight safety and operation, and would normally be the primary person liable for an infraction of any flight rule. The strict legal definition of PIC may vary slightly from country to country. The International Civil Aviation Organization (ICAO) definition is: "The pilot responsible for the operation and safety of the aircraft during flight time." In Annex 2, "Rules of the Air", under par. "2.3.1 Responsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce RB211
The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce Holdings, Rolls-Royce. The engines are capable of generating of thrust. The RB211 engine was the first production turbofan#Three-spool, three-spool engine and turned Rolls-Royce from a significant player in the aero-engine industry into a global leader. Originally developed for the Lockheed L-1011 TriStar, it entered service in 1972 and was the exclusive engine to power the L-1011. Mismanagement of the initial development and consequent cost issues led to the effective nationalisation of Rolls-Royce Limited, to save the workforce and the engine businesses important to the UK and many other aerospace and aircraft operating companies. In the early 1970s, the engine was reckoned by the company to be capable of at least 50 years of continuous development. The RB.211 was renamed, in 1989, to become the basis of the Rolls-Royce Trent family of engines when the RB211-524L was renamed to the ...

Serial Number
A serial number (SN) is a unique identifier used to ''uniquely'' identify an item, and is usually assigned incrementally or sequentially. Despite being called serial "numbers", they do not need to be strictly numerical and may contain letters and other typographical symbols, or may consist entirely of a character (computing), character string (computer science), string. Applications of serial numbering Serial numbers identify otherwise identical individual units, thereby serving various practical uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones. They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected. Some items with ...

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a time. The NAA a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Airlines Flight 77
American Airlines Flight 77 was a scheduled domestic transcontinental passenger flight from Dulles International Airport in Northern Virginia to Los Angeles International Airport in Los Angeles. The Boeing 757-200 aircraft serving the flight was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the Pentagon in Arlington County, Virginia, killing all 64 aboard and another 125 in the building. Flight 77 became airborne at 08:20 ET. Thirty-one minutes after takeoff, the attackers stormed the cockpit and forced the passengers and crew to the rear of the cabin, threatening the hostages but initially sparing all of them. Lead hijacker Hani Hanjour assumed control of the aircraft after having undergone extensive flight training as part of his preparation for the attack. In the meantime, two people aboard discreetly made phone calls to family members and relayed inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
