In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number.
The BAC One-Eleven is an early jet airliner produced by the British Aircraft Corporation (BAC). Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways (BUA) order on 9 May 1961. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to BUA on 22 January 1965. The 119-seat, stretched 500 series was introduced in 1967. Total production amounted to 244 until 1982 in the United Kingdom and between 1982 and 1989 in Romania where nine Rombac One-Elevens were licence-built by Romaero.
A stick shaker is a mechanical device designed to rapidly and noisily vibrate the control yoke of an aircraft, warning the flight crew that an imminent aerodynamic stall has been detected. It is typically present on the majority of large civil jet aircraft, as well as most large military planes.
This is a list of aviation-related events from 1963.
Banat Air Flight 166 was an Antonov Antonov An-24 chartered on 13 December 1995 from Romavia by Banat Air.
A stick pusher is a device installed in some fixed-wing aircraft to prevent the aircraft from entering an aerodynamic stall. Some large fixed-wing aircraft display poor post-stall handling characteristics or are vulnerable to deep stall. To prevent such an aircraft approaching the stall the aircraft designer may install a hydraulic or electro-mechanical device that pushes forward on the elevator control system whenever the aircraft's angle of attack reaches the predetermined value, and then ceases to push when the angle of attack falls sufficiently. A system for this purpose is known as a stick pusher.
Michael John Lithgow, OBE was a British aviator and chief test pilot for Vickers Supermarine who became the holder of the World Absolute Air Speed Record in 1953 flying a Supermarine Swift. He died when the prototype BAC One-Eleven airliner crashed in 1963.
Findlay Airport is 1 mile (1.6 km) southwest of Findlay, in Hancock County, Ohio.
Chicklade is a small village and civil parish in Wiltshire, South West England. The village is on the A303 road, about 7 miles (11 km) south of Warminster. The parish includes the hamlet of Upper Pertwood.
Philippine Air Lines Flight 158 was a flight from Mactan–Cebu International Airport to Manila International Airport near Manila which crashed on 12 September 1969. The aircraft, a BAC One-Eleven, struck a mango tree on the hill in sitio Kulaike, Antipolo, Rizal, located 22 km (12 nmi) east of its destination while on a VOR approach to runway 24. Of the 42 passengers and five crew members on board, only one passenger and one flight attendant survived. It was the deadliest aviation accident in the Philippines involving commercial aircraft until the crash of Philippine Airlines Flight 206 in 1987 and the deadliest involving a BAC One-Eleven until it was surpassed by Austral Líneas Aéreas Flight 9 in 1977.
Avensa Flight 358 was a scheduled airline flight from Maturín Airport to Simón Bolívar International Airport in Venezuela that crashed on 22 December 1974 killing all 75 people on board.
Trans World Airlines Flight 800 was an international scheduled passenger service from Kansas City, Missouri to Cairo, Egypt via Chicago, New York City, Paris, Milan, Rome, and Athens. The Boeing 707 caught fire following a rejected take off on runway 25 at Leonardo da Vinci–Fiumicino Airport, Rome at 13:09 GMT on a flight to Athens International Airport, Greece on November 23, 1964, killing 49 of the 74 people on board.
United Air Lines Flight 34 was a scheduled flight departing from San Francisco to Los Angeles, California, on December 27, 1936. At 7:36 am, the co-pilot requested the UAL localizer beacon at Burbank be turned on. The company radio requested aircraft position, to which the co-pilot replied, "just a minute." The aircraft crashed at the head of Rice Canyon at 7:38 am, killing all 12 passengers and crew. The probable cause was found to be "...an error on the part of the pilot for attempting to fly through Newhall pass at an altitude lower than the surrounding mountains without first determining by radio the existing weather."
On 3 June 1966, a newly built Hawker Siddeley Trident jetliner crashed during a pre-delivery test flight near the village of Felthorpe, Norfolk, England, killing all four crew. The aeroplane had entered a deep stall from which the crew were unable to recover. It was the first loss of a Trident aircraft.
Iberia Flight 602 was a domestic scheduled passenger flight operated by the Sud Aviation SE 210 Caravelle that took off from Valencia, Spain, bound for Ibiza on the Balearic island of Ibiza which crashed into a mountain near Ibiza Airport. All 98 passengers and 6 crew died in the crash.
Trans International Airlines Flight 863 was a ferry flight from John F. Kennedy International Airport in New York City to Washington Dulles International Airport. On September 8, 1970, the Douglas DC-8 crashed during take-off from JFK's runway 13R. None of the 11 occupants, who were all crew members, survived.
Flightline Flight 101 was an international flight from Barcelona El-Prat Airport in Barcelona, Spain to Ahmed Ben Bella Airport in Oran, Algeria. It crashed into the sea, probably due to a lightning strike leading to a loss of electricity.
Gabe 'Jock' Robb Bryce, OBE was a British aviator and chief test pilot for Vickers-Armstrong and later the British Aircraft Corporation. He flew, as pilot in command or Co-Pilot, the first flight of eleven prototype aircraft during his time as a test pilot, including the VC10.
Philippine Airlines Flight 124 was a domestic flight operated by Philippine Airlines that departed from Zamboanga International Airport, Zamboanga City to Manila International Airport, Manila.
