First Air Flight 6560
First Air Flight 6560 was a domestic charter flight that crashed on landing at Resolute, Nunavut, Canada, on 20 August 2011. Of the 15 people on board, 12 were killed and the remaining three were severely injured. The Boeing 737-200 of First Air was operating a service from Yellowknife, Northwest Territories, when it struck a hill in cloud near Resolute Bay Airport. The subsequent investigation found that a late initiation of the descent, the inadvertent partial disengagement of the autopilot during final approach, a drift in the aircraft compass system and poor communication between the flight crew resulted in the aircraft drifting significantly off course from the final approach path, descending into the ground moments after the crew initiated a go-around. History of the flight Flight 6560 had departed from Yellowknife Airport at 09:40 CDT (14:40 UTC) on 20 August for a flight to Resolute Bay Airport carrying 11 passengers, 4 crew members and freight.

Pilot Error
Pilot error generally refers to an Aviation accidents and incidents, accident in which an action or decision made by the Aircraft pilot#Airline, pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. Chicago Convention on International Civil Aviation, Chicago Convention defines accident as "An occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of the "pilot error" does not include deliberate crash (and such crash is not an accident). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs to teach crew members how t ...

Localizer
An instrument landing system localizer, or simply localizer (LOC), is a system of horizontal guidance in the instrument landing system, which is used to guide aircraft along the axis of the runway. Principle of operation In aviation, a localizer is the lateral component of the ''instrument landing system'' (ILS) for the runway centerline when combined with the vertical glide slope, not to be confused with a locator, although both are parts of aviation navigation systems. A localizer (like a glideslope) requires both a transmitting airport runway system and receiving cockpit instruments. An older aircraft without an ILS receiver cannot take advantage of any ILS facilities at any runway, and much more importantly, the most modern aircraft have no use of their ILS instruments at runways which lack ILS facilities. In parts of Africa and Asia large airports may lack any kind of transmitting ILS system. Some runways have ILS only in one direction, this can however still be used for t ...

Crew Resource Management
Crew resource management or cockpit resource management (CRM)Diehl, Alan (2013) "Air Safety Investigators: Using Science to Save Lives-One Crash at a Time." Xlibris Corporation. . http://www.prweb.com/releases/DrAlanDiehl/AirSafetyInvestigators/prweb10735591.htm is a set of training procedures for use in environments where human error can have devastating effects. CRM is primarily used for improving aviation safety and focuses on interpersonal communication, leadership, and decision making in aircraft cockpits. Its founder is David Beaty, a former Royal Air Force and a BOAC pilot who wrote "The Human Factor in Aircraft Accidents" (1969). Despite the considerable development of electronic aids since then, many principles he developed continue to prove effective. CRM in the US formally began with a National Transportation Safety Board (NTSB) recommendation written by NTSB Air Safety Investigator and aviation psychologist Alan Diehl Air Crash Investigation: Focused on Failure"''D ...

North Magnetic Pole
The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the Earth's magnetic field, planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down). There is only one location where this occurs, near (but distinct from) the geographic north pole. The Geomagnetic pole, geomagnetic north pole is the northern Antipodes, antipodal pole of an ideal dipole model of the Earth's magnetic field, which is the most closely fitting model of Earth's actual magnetic field. The north magnetic pole moves over time according to magnetic changes and flux lobe Elongation (materials science), elongation in the Earth's outer core. In 2001, it was determined by the Geological Survey of Canada to lie west of Ellesmere Island in northern Canada at . It was situated at in 2005. In 2009, while still situated within the Canadian ...

Control Column
A yoke, alternatively known as a control wheel or a control column, is a device used for piloting some fixed-wing aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 563. Aviation Supplies & Academics, 1997. . The pilot uses the yoke to control the attitude of the plane, usually in both pitch and roll. Rotating the control wheel controls the ailerons and the roll axis. Fore and aft movement of the control column controls the elevator and the pitch axis. When the yoke is pulled back, the nose of the aircraft rises. When the yoke is pushed forward, the nose is lowered. When the yoke is turned left, the plane rolls to the left, and when it is turned to the right, the plane rolls to the right. Small to medium-size aircraft, usually limited to propeller-driven, feature a mechanical system whereby the yoke is connected directly to the control surfaces with cables and rods. Human muscle power alone is not enough for larger and more powerful aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instrument Landing System
In aviation, the instrument landing system (ILS) is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. In its original form, it allows an aircraft to approach until it is over the ground, within a of the runway. At that point the runway should be visible to the pilot; if it is not, they perform a missed approach. Bringing the aircraft this close to the runway dramatically increases the range of weather conditions in which a safe landing can be made. Other versions of the system, or "categories", have further reduced the minimum altitudes, runway visual ranges (RVRs), and transmitter and monitoring configurations designed depending on the normal expected weather patterns and airport safety requirements. ILS uses two directional radio signals, the ''localizer'' (108 to 112 MHz frequency), which provides horizontal guidance, and the ''glideslope'' (329.15 to 335 MHz frequency ...

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

Transportation Safety Board Of Canada
The Transportation Safety Board of Canada (TSB, french: Bureau de la sécurité des transports du Canada, BST), officially the Canadian Transportation Accident Investigation and Safety Board (french: link=no, Bureau canadien d'enquête sur les accidents de transport et de la sécurité des transports) is the agency of the Government of Canada responsible for advancing transportation safety in Canada. It is accountable to Parliament directly through the President of the King’s Privy Council and the Minister of Intergovernmental and Northern Affairs and Internal Trade. The independent agency investigates accidents and makes safety recommendations in four modes of transportation: aviation, rail, marine and pipelines. Agency history Prior to 1990, Transport Canada's Aircraft Accident Investigation Branch (1960–1984) and its successor the Canadian Aviation Safety Board or CASB (1984–1990) were responsible for investigation of air incidents. Before 1990, investigations and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravel Kit
A gravel kit is a modification on an aircraft to avoid foreign object debris (FOD) damage or ingestion while operating on unpaved surfaces. Modifications generally include methods of preventing the nose gear spraying FOD into the engine and onto the underside of the fuselage or wings, and methods of preventing each engine from ingesting FOD from the ground directly in front of it. Examples of planes that can be fitted with this upgrade include the Boeing 737-200, which includes a gravel deflector (similar in appearance to a wide ski) mounted to the nose wheel, and vortex dissipators, using compressor bleed air, in front of each engine. This modification was used by Alaska Airlines for many years, and is still employed by Air Inuit, Canadian North, Air North, Nolinor Aviation and First Air in northern Canada. Some Boeing 727s were also fitted with specific gravel kits on the nose wheel, while the rest were fitted with devices in the form of smaller deflectors than those used on the ...

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combi Aircraft
Combi aircraft in commercial aviation are aircraft that can be used to carry either passengers as an airliner, or cargo as a freighter, and may have a partition in the aircraft cabin to allow both uses at the same time in a mixed passenger/freight combination. The name ''combi'' comes from the word ''combination''. The concept previously existed in railroading, as a passenger car that contained a separate compartment for mail and/or baggage. Combi aircraft typically feature an oversized cargo door, as well as tracks on the cabin floor to allow the seats to be added or removed quickly. Typically, configured for both passenger and cargo duty, the passenger compartment is pressurized to a higher pressure, to prevent potential fumes from cargo entering the passenger area. Airlines Northwest Airlines In 1963, Northwest Airlines operated a domestic and International routing with a Douglas DC-7C four engine propeller aircraft between New York Idlewild Airport (which would subsequ ...
