A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout.
The empennage, also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow. The term derives from the French language verb empenner which means "to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces.
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw. It is part of the aircraft empennage, specifically of its stabilizers.
An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable surface such as a stabilator. Depending on the context, "stabilizer" may sometimes describe only the front part of the overall surface.
Aircraft upset is a dangerous condition in aircraft operations in which the flight attitude or airspeed of an aircraft is outside the normal bounds of operation for which it is designed. This may result in the loss of control (LOC) of the aircraft, and sometimes the total loss of the aircraft itself. Loss of control may be due to excessive altitude for the airplane's weight, turbulent weather, pilot disorientation, or a system failure.
Kenneth Kaunda International Airport is an international airport located in Chongwe District, off the Great East Road, approximately 27 kilometres (17 mi) northeast of the city centre of Lusaka, the capital and largest city of Zambia. The airport has a capacity of 6 million and is the largest in Zambia, serving as a hub for its region. The airport serves as a hub for Zambia Airways, Proflight Zambia, Royal Zambian Airlines, and Mahogany Air.
BOAC Flight 911 was a round-the-world flight operated by the British Overseas Airways Corporation (BOAC) that crashed near Mount Fuji in Japan on 5 March 1966, with the loss of all 113 passengers and 11 crew members. The Boeing 707 jetliner involved disintegrated mid-air shortly after departing from Tokyo, as a result of severe clear-air turbulence.
International Aviation Services Limited, trading as IAS Cargo Airlines from 1975, is a defunct wholly privately owned, independent British airline that was based at London Gatwick Airport in the United Kingdom. It commenced operations in 1967 and went bankrupt in 1980, following a merger with London Stansted based Trans Meridian Air Cargo (TMAC) to form the short-lived British Cargo Airlines.
Zambia Airways is the flag carrier of the Republic of Zambia. The airline is based in Lusaka, Zambia with its hub at Kenneth Kaunda International Airport.
On 31 December 1968 a Vickers Viscount aircraft departed from Perth, Western Australia for a flight of 724 nautical miles (1 341 km) to Port Hedland. The aircraft crashed 28 nautical miles (52 km) short of its destination with the loss of all twenty-six people on board. More than half of the right wing, from outboard of the inner engine to the wingtip, including the outer engine and its propeller, broke away from the rest of the aircraft in flight and struck the ground a significant distance from the main wreckage. Investigation by the Australian Department of Civil Aviation and British Aircraft Corporation concluded that a mysterious action during maintenance led to extensive fatigue cracking in the right wing spar. This accident remains the third worst in Australia's civil aviation history.
British European Airways Flight 706 (BE706/BEA706) was a scheduled international passenger flight from United Kingdom to Salzburg, Austria. On 2 October 1971, whilst en route at 19,000 feet (5,791 m), the Vickers Vanguard suffered a failure with its rear cabin pressure bulkhead. The resulting depressurisation of the tail section caused the surfaces of the tailplanes to separate. The aircraft entered an uncontrollable dive and crashed near Aarsele, Belgium, killing all 63 passengers and crew on impact. A piece of debris from the aircraft struck a passing car, causing minor injuries to one of its occupants.
On 31 January 1945 a Stinson Model A aircraft departed from Melbourne for a flight of 127 nautical miles (235 km) to Kerang, Victoria—the first leg of an Australian National Airways regular scheduled service to Broken Hill, New South Wales. It crashed 50 nmi (93 km) from Melbourne. All ten occupants were killed in the accident. The aircraft was one of four Stinsons imported in 1936 by Airlines of Australia (AoA). Three had now crashed with the loss of 17 lives, and the fourth would not be permitted to fly again.
Nigeria Airways Flight 9805 was a cargo flight from King Abdulaziz International Airport in Jeddah to Mallam Aminu Kano International Airport in Kano, Nigeria. On 19 December 1994, the Boeing 707-3F9C flying the route suffered an in-flight fire and crashed into a marshland near Kiri Kasama, Hadejia LGA, Nigeria. One of the three crew members and both passengers died. The investigation determined that a heat generating substance was the probable cause.
Ameristar Charters Flight 9363 was an air charter flight from Willow Run Airport in Ypsilanti, Michigan to Dulles International Airport in Dulles, Virginia, which experienced a rejected takeoff and runway excursion on March 8, 2017 as the result of a jammed elevator; the McDonnell Douglas MD-83 operating the flight was substantially damaged, but only one injury and no fatalities occurred to the 116 crew and passengers on board.
Trans-Air Service Flight 671 was a cargo flight from Luxembourg Airport to Mallam Aminu Kano International Airport in Kano, Nigeria. While flying over France on March 31, 1992, the Boeing 707 operating the flight experienced an in-flight separation of two engines on its right wing. Despite the damage to the aircraft, the pilots were able to perform an emergency landing at Istres-Le Tubé Air Base in Istres, France. All five occupants of the aircraft survived; however, the aircraft was damaged beyond repair due to a fire on the right wing.
Omega Aerial Refueling Services Flight 70 was a flight supposed to provide aerial refueling to US Navy F/A 18s. It crashed on take-off following an engine separation.
