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 ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

ATR-72
The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR (french: Avions de transport régional or it, Aerei da Trasporto Regionale), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A.). The number "72" in its name is derived from the aircraft's typical standard seating capacity of 72 passengers. During the 1980s, French aerospace company Aérospatiale and Italian aviation conglomerate Aeritalia merged their work on a new generation of regional aircraft. For this purpose, a new jointly owned company was established, ATR, for the purpose of developing, manufacturing, and marketing their first airliner, which was later designated as the ATR 42. On 16 August 1984, the first model of the series, designated as the ATR 42-300, performed the type's maiden flight. During the mid-1980s, the ATR 72 was developed ...

Pitot-static System
A pitot-static system is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft's airspeed, Mach number, altitude, and altitude trend. A pitot-static system generally consists of a pitot tube, a static port, and the pitot-static instruments. Other instruments that might be connected are air data computers, flight data recorders, altitude encoders, cabin pressurization controllers, and various airspeed switches. Errors in pitot-static system readings can be extremely dangerous as the information obtained from the pitot static system, such as altitude, is potentially safety-critical. Several commercial airline disasters have been traced to a failure of the pitot-static system. Pitot-static pressure The pitot-static system of instruments uses the principle of air pressure gradient. It works by measuring pressures or pressure differences and using these values to assess the speed and altitude. These pressures can be measured ei ...

Aeroperú Flight 603
Aeroperú Flight 603 was a scheduled passenger flight from Miami International Airport in Miami, Florida, to Comodoro Arturo Merino Benítez International Airport in Santiago, Chile, with stopovers in Quito, Ecuador, and Lima, Peru. On October 2, 1996, the Boeing 757-23A aircraft flying the final leg of the flight crashed, killing all 70 people aboard. Flying over water, at night, with no visual references, the pilots were unaware of their true altitude, and struggled to control and navigate the aircraft. The investigation determined that the air data computers were unable to show correct airspeed and altitude on cockpit displays because a maintenance worker had failed to remove tape covering the pitot-static system ports on the aircraft exterior. Overview Aircraft The aircraft, a Boeing 757-23A was delivered new from Boeing on December 2, 1992, to Ansett Worldwide. It was leased to Aeroméxico on 27 September 1993 and then sub-leased to Aeroperú on April 1, 1994. The lease ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
