American Airlines Flight 514
American Airlines Flight 514 was a training flight from Idlewild International Airport, to the Grumman Aircraft Corp. airfield. On the afternoon of August 15, 1959, the Boeing 707 operating the flight crashed near the Calverton airport, killing all five crew members aboard. This was the first accident to involve a Boeing 707, which had only gone into service in October of the previous year. Aircraft The aircraft was a Boeing 707-123 with registration N7514A, nicknamed "Flagship Connecticut". The aircraft in question's first flight was earlier in the year, and when the crash occurred, it had accumulated 736 total flight hours. The 707s had gone into service with American on January 25, 1959, with flights from New York to Los Angeles. The Calverton airfield was used frequently by American Airlines for training purposes for crew members on 707s, and was known then as the Grumman Aircraft Corp. field. Crew There were five people onboard the aircraft. Captain Harry C. Job acted as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loss Of Control (aeronautics)
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight, and is a significant factor in several Aviation accidents and incidents, aviation accidents worldwide and the leading cause of jet fatalities worldwide. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses. Causes Aircraft experiencing a loss of control depart from normal flight and can reach attitudes or situations from which it is impossible for them to be recovered. Due to the certification and design processes, it is extremely rare for aircraft to experience a loss of control without extreme mishandling or a technical defect. A NASA study on aircraft loss of control causal factors and mitigation challenges developed a preliminary list of causal factors that contribute to loss of control compiled through interviews, reviews of accident reports and team analysis of available dat ...

Crosswind Landing
In aviation, a crosswind landing is a landing maneuver in which a significant component of the prevailing wind is perpendicular to the runway center line. Significance Aircraft in flight are subject to the direction of the winds in which the aircraft is operating. For example, an aircraft in flight that is pointed directly north along its longitudinal axis will, generally, fly in that northerly direction. However, if there is a west wind, the actual track of the aircraft will be slightly to the east of north. If the aircraft were landing north on a north-south runway, it would need to compensate for this easterly drift caused by the west crosswind. In situations where a crosswind is present, the aircraft will drift laterally as it approaches the runway. This drift poses significant safety issues because safe operation of the undercarriage requires the body and track of the aircraft to be aligned with the runway at touch down. The landing gear designs of the "pioneer era" 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pan Am
Pan American World Airways, originally founded as Pan American Airways and commonly known as Pan Am, was an American airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. It was the first airline to fly worldwide and pioneered numerous innovations of the modern airline industry such as jumbo jets, and computerized reservation systems. Until its dissolution in 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two former U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. Under the leadership of American entrepreneur Juan Trippe, in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Airlines Flight 320
American Airlines Flight 320 was a scheduled flight between Chicago Midway International Airport and New York City's LaGuardia Airport. On February 3, 1959, the Lockheed L-188 Electra performing the flight crashed into the East River during its descent, killing 65 of the 73 people on board. Poor weather conditions at the destination meant that the crew had to descend through dense clouds and fog, but the aircraft flew lower than the pilots intended and it crashed into the icy river short of the runway at a speed of . American Airlines had been flying the type of aircraft in commercial service for only about two weeks before the accident. Eyewitnesses to the accident reported that the aircraft was flying significantly lower than was normal for planes approaching the airport, while surviving flight crew members claimed that the aircraft's instruments had told them that the flight was operating at safe altitudes right up to the moment of impact.

Stall (fluid Mechanics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thru ...

Aircraft Principal Axes
An aircraft in flight is free to rotate in three dimensions: '' yaw'', nose left or right about an axis running up and down; ''pitch'', nose up or down about an axis running from wing to wing; and ''roll'', rotation about an axis running from nose to tail. The axes are alternatively designated as ''vertical'', ''lateral'' (or ''transverse''), and ''longitudinal'' respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of gravity. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the win ...

Steady Flight
Steady flight, unaccelerated flight, or equilibrium flight is a special case in flight dynamics where the aircraft's linear and angular velocity are constant in a body-fixed reference frame. Basic aircraft maneuvers such as level flight, climbs and descents, and coordinated turns can be modeled as steady flight maneuvers. Typical aircraft flight consists of a series of steady flight maneuvers connected by brief, accelerated transitions. Because of this, primary applications of steady flight models include aircraft design, assessment of aircraft performance, flight planning, and using steady flight states as the equilibrium conditions around which flight dynamics equations are expanded. Reference frames Steady flight analysis uses three different reference frames to express the forces and moments acting on the aircraft. They are defined as: * Earth frame (assumed inertial) ** Origin - arbitrary, fixed relative to the surface of the Earth ** ''xE'' axis - positive in the directio ...
