In aviation, run-up, or runup, is the series of last-minute checks performed by pilots on an aircraft prior to take-off. Run-ups are also sometimes performed by aircraft mechanics. This could occur at a gate in between flights or elsewhere to test engines and diagnose engine problems.
The checks performed during a run-up vary with the type of aircraft and (to a lesser extent) with the operating rules under which the flight is being conducted, e.g., instrument flight rules, visual flight rules, operation as a commercial carrier or private pilot, and so on. The term run-up alludes to engine checks that involve temporarily advancing the throttles to ensure that engines are capable of producing take-off thrust, although not all run-up procedures involve such checks.
A run-up area is a location at an airport where pilots can perform run-up checks of their aircraft. They exist because air blast from engine verification may cause problems for other aircraft or structures, so a special area where such checks will do no harm is set aside for them. They also allow aircraft to temporarily leave taxiways so that they don't obstruct ground traffic while the run-up is performed. For these reasons, run-up areas are typically located near runways.
For safety reasons, run-ups on large transport-category aircraft require the utmost coordination between the cockpit crew and the ground crew. On January 16, 2006 an experienced mechanic was inspecting the #2 engine of a Boeing 737-500 during a run-up when he accidentally positioned himself too close to the engine's intake. With the engine running near takeoff thrust, he was ingested into the engine and died as a result. [1] In late March 2020, an American Eagle CRJ doing an engine run-up caused a hangar to flip and land on its roof while also damaging two privately owned aircraft at San Luis Obispo airport. [2]
Aviation is the design, development, production, operation, and use of aircraft, especially heavier-than-air aircraft. Articles related to aviation include:
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.
Scandinavian Airlines System Flight 751 was a regularly scheduled Scandinavian Airlines passenger flight from Stockholm, Sweden, to Warsaw, Poland, via Copenhagen, Denmark. On 27 December 1991, a McDonnell Douglas MD-81 operating the flight, registration OY-KHO, piloted by Danish Captain Stefan G. Rasmussen (44) and Swedish first officer Ulf Cedermark (34), both experienced pilots with 8,000 and 3,000 flight hours, respectively, was forced to make an emergency landing in a field near Gottröra, Sweden. Ice had collected on the wings' inner roots before takeoff, broke off, and was ingested into the engines as the aircraft became airborne on takeoff, ultimately disabling both engines. All 129 passengers and crew aboard survived.
In all forms of aviation, ground crew are personnel that service aircraft while on the ground, during routine turn-around; as opposed to aircrew, who operate all aspects of an aircraft whilst in flight. The term ground crew is used by both civilian commercial airlines and in military aviation.
Air Midwest Flight 5481 was a Beechcraft 1900D on a regularly scheduled passenger flight from Charlotte Douglas International Airport in Charlotte, North Carolina, to Greenville–Spartanburg International Airport in Greer, South Carolina. On the morning of January 8, 2003, the Beechcraft stalled while departing Charlotte Douglas International Airport and crashed into an aircraft hangar, killing all 21 passengers and crew aboard and injuring one person on the ground.
American Airlines Flight 157, a Douglas DC-6, departed on November 29, 1949, from New York City bound for Mexico City with 46 passengers and crew. After one engine failed in mid-flight, a series of critical mistakes by the flight crew caused the pilot to lose control of the plane during the final approach to a routine stopover at Love Field in Dallas, Texas. The airliner slid off the runway and struck a parked airplane, a hangar, and a flight school before crashing into a business across from the airport. 26 passengers and two flight attendants died. The pilot, co-pilot, flight engineer, and 15 passengers survived.
Southern Airways Flight 242 was a flight from Muscle Shoals, Alabama, to Atlanta, Georgia, with a stop in Huntsville, Alabama. On April 4, 1977, it executed a forced landing on Georgia State Route 381 in New Hope, Paulding County, Georgia, United States, after suffering hail damage and losing thrust on both engines in a severe thunderstorm.
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.
Mohawk Airlines Flight 405, a Fairchild Hiller FH-227 twin-engine turboprop airliner registered N7818M, was a domestic scheduled passenger flight operated by Mohawk Airlines that crashed into a house within the city limits of Albany, New York, on March 3, 1972, on final approach to Albany County Airport, New York, killing 17 people. The intended destination airport lies in the suburban Town of Colonie, about 4 miles north of the crash site.
TAM Transportes Aéreos Regionais Flight 402 was a scheduled domestic flight from Caxias do Sul, Brazil, to Recife International Airport in Recife, via São Paulo–Congonhas International Airport and Santos Dumont Airport in Rio de Janeiro. On 31 October 1996, at 8:27 (UTC-2), the starboard engine of the Fokker 100 operating the route reversed thrust while the aircraft was climbing away from the runway at Congonhas. The aircraft stalled and rolled beyond control to the right, then struck two buildings and crashed into several houses in a heavily populated area only 25 seconds after takeoff. All 95 people on board were killed, as well as another 4 on the ground. It is the fourth deadliest accident in Brazilian aviation history, the second at the time. It is also the deadliest aviation accident involving a Fokker 100.
Airbus Industrie Flight 129 was an Airbus Industrie A330-321 test flight that ended in a crash on 30 June 1994 at Toulouse-Blagnac Airport, killing all seven people aboard. The last test flown was to certify the plane's takeoff capability with a single engine failure. It was the first fatal accident involving an Airbus A330 as well as the first hull loss of the type. It remained the only fatal accident involving an A330 until the crash of Air France Flight 447 on 1 June 2009.
British Airways Flight 38 was a scheduled international passenger flight from Beijing Capital International Airport in Beijing, China, to London Heathrow Airport in London, United Kingdom, an 8,100-kilometre trip.

A jet blast deflector (JBD) or blast fence is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury. The structure must be strong enough to withstand heat and high speed air streams as well as dust and debris carried by the turbulent air. Without a deflector, jet blast can be dangerous to people, equipment, vehicles and other aircraft.
Kish Air Flight 7170 was a scheduled international passenger flight from Kish Island in Iran to Sharjah, United Arab Emirates, operated by Iranian airline Kish Air. On February 10, 2004, the aircraft serving the route, a Fokker 50, lost control and crashed onto terrain while on approach to Sharjah International Airport. A total of 43 out of 46 people on board were killed in the crash, making it the deadliest air disaster involving the Fokker 50.
On April 4, 1955, a United Airlines Douglas DC-6 named Mainliner Idaho crashed shortly after taking off from Long Island MacArthur Airport, in Ronkonkoma, Islip, New York, United States.
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 worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses.
United Airlines Flight 2885 was a scheduled cargo flight from Cleveland to Los Angeles, with stopover in Detroit. On January 11, 1983, a DC-8 operating as Flight 2885 crashed after take-off from Detroit, killing all three crew members. The National Transportation Safety Board (NTSB) investigation determined that the cause for the crash was pilot error. A radioactive package was found on board, but no radioactive material was spilled.
