Eastern Air Lines Flight 401
Eastern Air Lines Flight 401 was a scheduled flight from John F. Kennedy International Airport in Queens, New York, United States, to Miami International Airport in Miami, Florida, United States. Shortly before midnight on December 29, 1972, the Lockheed L-1011-1 TriStar crashed into the Florida Everglades. All three cockpit crew members, two of the 10 flight attendants, and 96 of the 163 passengers were killed. Seventy-five people survived, with 58 of them suffering serious injuries. The crash occurred while the entire flight crew were preoccupied with a burnt-out landing gear indicator light. The captain bumped the yoke on the aircraft, causing it to turn off the autopilot. Due to the focus on the landing gear and the minimal changes in the cockpit, the pilots did not notice. Because of this, the aircraft gradually lost altitude and crashed. This was the first hull loss and fatal crash of a Lockheed L-1011 TriStar. It was also the first severe widebody aircraft crash. Airc ...

Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, fully under pilot control, is unintentionally flown into the ground, a body of water or other obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending collision until impact, or it is too late to avert. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are classified instead as uncontrolled flight into terrain, or UFIT. Incidents resulting from the deliberate action of the person at the controls, such as a forced landing, an act of terrorism, or suicide by pilot, are also excluded from the definition of CFIT. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircra ...

Hull Loss
A hull loss is an aviation accident that damages the aircraft beyond economic repair, resulting in a total loss. The term also applies to situations where the aircraft is missing, the search for its wreckage is terminated, or the wreckage is logistically inaccessible. The aviation industry uses the metric of "hull losses per 100,000 flight departures" to measure the relative risk of a given flight or aircraft. There is no official ICAO or NTSB definition. From 1959 to 2006, 384 of 835 hull losses were non-fatal. Constructive hull loss takes into account other incidental expenses beyond repair, such as salvage, logistical costs of repairing non- airworthy aircraft within the confines of the incident site, and recertifying the aircraft. Airlines typically have insurance to cover hull loss. Their policies—like many covering assets that are subject to depreciation—typically pay the insured a formulaic used-item value. A damaged aircraft will often simply be scrapped. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has three regional offices, located in Anchorage, Alaska; Aurora, Colorado; and Federal Way, Washington. The agency also operated a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the time the CAA/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cockpit Voice Recorder
A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. The device may often be referred to colloquially as a "black box", an outdated name which has become a misnomer—they are now required to be painted Safety orange, bright orange, to aid in their recovery after accidents. There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation. The two flight recorders are required by international regulation, overseen by the Internation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chord (music)
In Western music theory, a chord is a group of notes played together for their harmony, harmonic Consonance and dissonance, consonance or dissonance. The most basic type of chord is a Triad (music), triad, so called because it consists of three distinct notes: the Root (chord), root note along with Interval (music), intervals of a Third (chord), third and a Fifth (chord), fifth above the root note. Chords with more than three notes include added tone chords, extended chords and tone clusters, which are used in contemporary classical music, jazz, and other genres. Chords are the building blocks of harmony and form the harmonic foundation of a piece of music. They provide the harmonic support and coloration that accompany melodies and contribute to the overall sound and mood of a musical composition. The factor (chord), factors, or component notes, of a chord are often sounded simultaneously but can instead be sounded consecutively, as in an arpeggio. A succession of chords is ca ...

C (musical Note)
C or Do is the first note of the C major scale, the third note of the A minor scale (the relative minor of C major), and the fourth note (G, A, B, C) of the Guidonian hand, commonly pitched around 261.63 Hz. The actual frequency has depended on historical pitch standards, and for transposing instruments a distinction is made between written and sounding or concert pitch. It has enharmonic equivalents of B and D. In English the term ''Do'' is used interchangeably with C only in the context of fixed Do solfège; in the movable Do system Do refers to the tonic of the prevailing key. Frequency Historically, concert pitch has varied. For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies). Scientific pitch was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256&nb ...

Holding Pattern
In aviation, holding (or flying a hold) is a maneuver designed to delay an aircraft already in flight while keeping it within a specified airspace; i.e. "going in circles." Implementation A holding pattern for instrument flight rules (IFR) aircraft is usually a racetrack pattern based on a ''holding fix''. This ''fix'' can be a radio beacon such as a non-directional beacon (NDB) or VHF omnidirectional range (VOR). The fix is the start of the first turn of the racetrack pattern. Aircraft will fly towards the fix, and once there will enter a predefined racetrack pattern. A standard holding pattern uses right-hand turns and takes approximately 4 minutes to complete (one minute for each 180-degree turn, and two one-minute straight ahead sections). Deviations from this pattern can happen if long delays are expected; longer legs (usually two or three minutes) may be used, or aircraft with distance measuring equipment (DME) may be assigned patterns with legs defined in nautical ...

Deadheading (employee)
Deadheading is the practice of carrying, free of charge, a transport company's own staff on a normal passenger trip so that they can be in the right place to begin their duties. In United States railway usage, the term may also be used for movement of train crews to or from a train using another means of vehicular transportation, as passenger train service is infrequent or nonexistent in many areas. Notable deadheaders * One of the four survivors of Japan Air Lines Flight 123 in August 1985 was a deadheading flight attendant, Yumi Ochiai. She helped administer oxygen to passengers after the plane suffered explosive decompression. She survived because she was wedged between several seats during the crash, protecting her from suffering serious injury. * In July 1989, United Airlines Flight 232, a McDonnell Douglas DC-10, lost all hydraulic systems and flight controls, an event considered so improbable that no backup flight controls were provided and no emergency procedures had ...

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 ...
