Taxiing is the movement of an aircraft on the ground, under its own power, in contrast to towing or pushback where the aircraft is moved by a tug. The aircraft usually moves on wheels, but the term also includes aircraft with skis or floats.
Landing is the last part of a flight, where a flying animal, aircraft, or spacecraft returns to the ground. When the flying object returns to water, the process is called alighting, although it is commonly called "landing", "touchdown" or "splashdown" as well. A normal aircraft flight would include several parts of flight including taxi, takeoff, climb, cruise, descent and landing.
An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations.
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines. There have been accidents involving thrust reversal systems, including fatal ones.
In aeronautics, a spoiler is a device which intentionally reduces the lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to spoil the streamline flow. By so doing, the spoiler creates a controlled stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag.
In aviation, autoland describes a system that fully automates the landing procedure of an aircraft's flight, with the flight crew supervising the process. Such systems enable airliners to land in weather conditions that would otherwise be dangerous or impossible to operate in.
The Learjet 25 is an American ten-seat, twin-engine, high-speed business jet aircraft manufactured by Learjet. It is a stretched version of the Learjet 24.
Qantas Flight 1 was a Qantas passenger flight between Sydney and London that was involved in a runway overrun accident at Don Mueang International Airport in Bangkok on 23 September 1999 as it was landing for a stopover.
USAir Flight 5050 was a passenger flight that crashed on takeoff from LaGuardia Airport in Queens, New York. As the plane took off from LaGuardia's runway 31, the plane drifted to the left. After hearing a loud bang, the pilots attempted to reject the takeoff, but were unable to stop the plane short of the end of the runway. The plane continued past the end of the runway and plunged into Bowery Bay. Two passengers were killed.
Southwest Airlines Flight 1248 was a scheduled passenger flight from Baltimore, Maryland, to Chicago, Illinois, continuing on to Salt Lake City, Utah, and then to Las Vegas, Nevada. On December 8, 2005, the airplane slid off a runway at Chicago-Midway while landing in a snowstorm and crashed into automobile traffic, killing a six-year-old boy.
A takeoff/go-around switch is a switch on the autothrottle of modern large aircraft, with two modes: takeoff (TO) and go-around (GA). The mode is dependent on the phase of flight; usually, on approach to land, the autopilot will be set to approach mode, therefore if the TO/GA switch is pressed it will activate the go-around mode of the autothrottle (about 90–92% N1, if pressed again, go around thrust will increase to full ; conversely, when takeoff is set on the autopilot, the switch activates takeoff mode of the autothrottle. On Boeing aircraft TO/GA modes are selected by a separate button near the throttle levers, but on Airbus aircraft it is activated by advancing the thrust levers forward to the TO/GA detent.
In aviation terminology, a rejected takeoff (RTO) or aborted takeoff is the situation in which the pilot decides to abort the takeoff of an airplane after initiating the takeoff roll but before the airplane leaves the ground.
S7 Airlines Flight 778(S7778/SBI778) was a scheduled domestic passenger flight from Moscow to Irkutsk, Russia. On 9 July 2006, at 06:44 local time, the Airbus A310-324 aircraft operating the route overran the runway during its landing in Irkutsk. The aircraft failed to stop and crashed through the airport's concrete perimeter fence, struck rows of private garages and burst into flames, killing 125 people.
Lufthansa Flight 2904 was an Airbus A320-200 flying from Frankfurt, Germany to Warsaw, Poland that overran the runway at Okęcie International Airport on 14 September 1993.
Britannia Airways Flight 226A was an international passenger flight from Cardiff, Wales to Girona, Spain, operated by charter airliner Britannia Airways. On 14 September 1999, the Boeing 757-204 aircraft suffered a crash landing and broke apart during a thunderstorm in Girona-Costa Brava Airport. Of the 236 passengers and nine crew on board, two were seriously injured and 41 sustained minor injuries. One of the passengers who had apparently sustained only minor injuries died five days later of unsuspected internal injuries. The aircraft involved in the crash, Boeing 757-204 registration G-BYAG, was damaged beyond economical repair and scrapped.
Sudan Airways Flight 109 was a scheduled international Amman–Damascus–Khartoum passenger flight, operated with an Airbus A310 by the flag carrier of Sudan, Sudan Airways. On 10 June 2008, at approximately 17:26 UTC, the Airbus A310 crashed on landing at Khartoum International Airport, killing 30 of the 214 occupants on board.
Brake to Vacate (BTV) is additional software planned by Airbus for incorporation on its line of airliners, intended to reduce runway overruns. A more tangible benefit is the increased ability to exit the runway at a specified turnoff point. The European Aviation Safety Agency certified the system, initially for use on the Airbus A380, in 2009. The second Airbus product to incorporate BTV will be the Airbus A320 family, which is much more widely used around the world than the A380. However, an A320 BTV system would be more modest, since its flight computer does not incorporate the extensive electronic architecture of the A380. The BTV is a very important part in the plane.
A flight control mode or flight control law is a computer software algorithm that transforms the movement of the yoke or joystick, made by an aircraft pilot, into movements of the aircraft control surfaces. The control surface movements depend on which of several modes the flight computer is in. In aircraft in which the flight control system is fly-by-wire, the movements the pilot makes to the yoke or joystick in the cockpit, to control the flight, are converted to electronic signals, which are transmitted to the flight control computers that determine how to move each control surface to provide the aircraft movement the pilot ordered.
Cathay Pacific Flight 780 was a flight from Juanda International Airport in Surabaya, Indonesia, to Hong Kong International Airport on 13 April 2010. On board were 309 passengers and a crew of 13. As Flight 780 neared Hong Kong, the crew were unable to change the thrust output of the engines. The aircraft, an Airbus A330-300, landed at almost twice the speed of a normal landing, suffering minor damage. The 57 passengers who sustained injuries were hurt in the ensuing slide evacuation; one of them received serious injuries.
Delta Air Lines Flight 1086 was a scheduled Delta Air Lines domestic passenger flight between Atlanta and New York's LaGuardia Airport. On March 5, 2015, the McDonnell Douglas MD-88 aircraft veered off the runway shortly after landing at LaGuardia Airport in New York City. The plane ran up the seawall berm and struck the perimeter fence, sliding along it for approximately 940 feet (290 m) before coming to rest with the nose of the aircraft hanging over the berm above Flushing Bay. There were no fatalities, although 29 people suffered minor injuries. The aircraft was seriously damaged and written off.
