A deadstick landing, also called a dead-stick landing or volplaning, is a type of forced landing when an aircraft loses all of its propulsive power and is forced to land. The "stick" does not refer to the flight controls, which in most aircraft are either fully or partially functional without engine power, but to the traditional wooden propeller, which without power would just be a "dead stick". [1] When a pilot makes an emergency landing of an aircraft that has some or all of its propulsive power still available, the procedure is known as a precautionary landing.
All fixed-wing aircraft have some capability to glide with no engine power; that is, they do not fall straight down like a stone, but rather continue to move horizontally while descending. For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi; 81 nmi) from a cruising altitude of 10,000 metres (33,000 ft). After a loss of power, the pilot’s goal is to maintain a safe airspeed and fly the descending aircraft to the most suitable landing spot within gliding distance, then land with the least amount of damage possible. The area open for potential landing sites depends on the original altitude, local terrain, the engine-out gliding capabilities of the aircraft, original airspeed and winds at various altitudes. Part of learning to fly a fixed-wing aircraft is demonstrating the ability to fly safely without an engine until prepared to make (or actually making) a landing. Gliders, unless they have an auxiliary motor, do all their flying without power, and trained pilots can touch down on virtually any spot they pick from the air.
The success of the deadstick landing largely depends on the availability of suitable landing areas. A competent pilot gliding a relatively light, slow plane to a flat field or runway should result in an otherwise normal landing, since the maneuver is not especially difficult, requiring only strict attention and good judgement concerning speed and height. A heavier, faster aircraft or a plane gliding into mountains or trees could result in substantial damage.
With helicopters, a forced landing involves autorotation, since the helicopter glides by allowing its rotor to spin freely during the descent thus generating lift.
When a single engine aircraft suffers an engine failure, it must do a dead-stick landing. A danger comes from the pilot subsequently allowing a critical loss of airspeed, which will result in excessively fast loss of altitude and, when poorly handled, loss of control. The instinct to "stretch the glide" by pulling the nose up beyond its optimum point will simply make the aircraft sink faster.
Should the engine power be lost shortly after takeoff, the pilot(s) must evaluate their options: attempting a low-altitude turn back to the airport might be dangerous. This "impossible turn" has killed many pilots because it very likely will result in a crash whereas a landing straight ahead (or within a few degrees of the initial flight path) would be survivable. [2]
There have been several well-known instances of large jet airliners successfully executing a deadstick landing.
Air Canada Flight 143, commonly known as the Gimli Glider, was a Canadian scheduled domestic passenger flight between Montreal and Edmonton that ran out of fuel on Saturday, July 23, 1983, at an altitude of 41,000 feet (12,500 m), midway through the flight. The flight crew successfully glided the Boeing 767 to an emergency landing at a former Royal Canadian Air Force base in Gimli, Manitoba, which had been converted to a racetrack, Gimli Motorsports Park. It resulted in no serious injuries to passengers or persons on the ground, and only minor damage to the aircraft. The aircraft was repaired and remained in service until its retirement in 2008. This unusual aviation accident earned the aircraft the nickname "Gimli Glider."
Aviation is the design, development, production, operation, and use of aircraft, especially heavier-than-air aircraft. Articles related to aviation include:
Air Transat is a Canadian airline based in Montreal, Quebec. Founded in 1986, it operates scheduled and charter flights serving 60 destinations in 25 countries. Air Transat is owned and operated by Transat A.T. Inc., with 37 aircraft registered with Transport Canada as of September 2023.
Cruise is the phase of aircraft flight that starts when the aircraft levels off after a climb, until it begins to descend for landing. Cruising usually comprises the majority of a flight, and may include small changes in heading, airspeed, and altitude.
Air Transat Flight 236 was a transatlantic flight bound for Lisbon, Portugal, from Toronto, Canada, that lost all engine power while flying over the Atlantic Ocean on August 24, 2001. The Airbus A330 ran out of fuel because of a fuel leak caused by improper maintenance. Captain Robert Piché, 48, an experienced glider pilot, and First Officer Dirk DeJager, 28, glided the plane to a successful emergency landing in the Azores, saving all 306 people on board. Most of the passengers on the flight were Canadians visiting Europe or Portuguese expatriates returning to visit family in Portugal. This was also the longest passenger aircraft glide without engines, gliding for nearly 65 nautical miles. Following this unusual aviation accident, this aircraft was nicknamed the "Azores Glider".
This is a list of aviation-related events from 2005.
An emergency landing is a premature landing made by an aircraft in response to an emergency involving an imminent or ongoing threat to the safety and operation of the aircraft, or involving a sudden need for a passenger or crew on board to terminate the flight. It typically involves a forced diversion to the nearest or most suitable airport or airbase, or an off airport landing or ditching if the flight cannot reach an airfield. Flights under air traffic control will be given priority over all other aircraft operations upon the declaration of the emergency.
Gimli Industrial Park Airport is a civilian airport and former military field located 2 nautical miles west of Gimli, Manitoba, Canada.
TACA Flight 110 was a scheduled international airline flight operated by TACA International Airlines, traveling from San Salvador to New Orleans, with a stopover in Belize City. On May 24, 1988, the flight encountered severe thunderstorm activity on its final approach to New Orleans International Airport. As a result, the brand new Boeing 737-300 suffered flameout in both engines while descending through a severe thunderstorm, but the pilots made a successful emergency landing on a grass levee adjacent to NASA's Michoud Assembly Facility, with no one aboard sustaining more than a few minor injuries, and with only minor hail damage to the intact aircraft. Following an on-site engine replacement, the jetliner took off from Saturn Boulevard, a road which had previously been an aircraft runway at Michoud. The aircraft was subsequently repaired and returned to service until it was finally retired in 2016.
In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading to loss of power or engine stoppage. There is still fuel in the tank(s), but it is unable to get to the engine(s) in sufficient quantity. By contrast, fuel exhaustion is an occurrence in which the vehicle in question becomes completely devoid of usable fuel, with results similar to those of fuel starvation.
Robert Piché is a retired Quebecer pilot. On August 24, 2001, he was captain of the Airbus A330 flying Air Transat Flight 236 and managed to land the aircraft safely in the Azores after it lost all power due to fuel exhaustion. As of November 2024, this remains a record glide length for a commercial aircraft in non-powered flight. Piché and his co-pilot were later assigned partial responsibility for the incident.
Turkish Airlines Flight 1951 was a passenger flight that crashed during landing at Amsterdam Schiphol Airport, the Netherlands, on 25 February 2009, resulting in the deaths of nine passengers and crew, including all three pilots.
Throughout a normal flight, a pilot controls an aircraft through the use of flight controls including maintaining straight and level flight, as well as turns, climbing, and descending. Some controls, such as a "yoke" or "stick" move and adjust the control surfaces which affects the aircraft's attitude in the three axes of pitch, roll, and yaw. Other controls include those for adjusting wing characteristics and those that control the power or thrust of the propulsion systems. The loss of primary control systems in any phase of flight is an emergency. Aircraft are not designed to be flown under such circumstances; however, some pilots faced with such an emergency have had limited success flying and landing aircraft with disabled controls.
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.
On June 28, 1998, United Airlines Flight 863, a Boeing 747-400 flying United's regularly scheduled transpacific service from San Francisco International Airport to Sydney Airport was forced to shut down one of its right-wing engines and nearly collided with San Bruno Mountain while recovering from the engine failure. The aircraft was able to dump fuel over the Pacific Ocean and return to San Francisco for an overweight landing, but the occurrence prompted United Airlines to change pilot training requirements.
