Unstabilized Approach
An unstable approach is an approach during which an aircraft does not maintain certain essential flight parameters within reasonable limits. This usually includes at least one of the following variables stable: speed, descent rate, vertical/lateral flight path and in landing configuration, or receive a landing clearance by a certain altitude. Unstabilized approaches account for most approach and landing accidents. For this reason, an approach should be stabilized by above runway altitude. Otherwise, a go-around should be executed by the pilot. For example, the 2016 Magdalen Islands Mitsubishi MU-2 crash On 29 March 2016, a Mitsubishi MU-2 operated by Aero Teknic, a Canadian aircraft maintenance company, crashed on approach to Îles-de-la-Madeleine Airport, killing former Canadian politician Jean Lapierre, several members of his family, and the t ... was blamed on an unstabilized approach.

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Flight Path
In the United States, airways or air routes are defined by the Federal Aviation Administration (FAA) in two ways: "VOR Federal airways and Low/Medium Frequency (L/MF) (Colored) Federal airways" These are designated routes which aeroplanes fly to aid in navigation and help with separation to avoid accidents. Airways are defined with segments within a specific altitude block, corridor width, and between fixed geographic coordinates for satellites navigation system, or between ground-based radio transmitter navigational aids (navaids; such as VORs or NDBs) or the intersection of specific radials of two navaids. United States To guide airmail pilots on their delivery routes, the United States Postal Service constructed the first airways in the United States, the Contract Air Mail routes. These airways were between major cities and identified at night by a series of flashing lights and beacons which pilots flew over in sequence to get from one city to the next. Intermediate ...

Aviation Accidents And Incidents
An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft, which takes place from the time any person boards the aircraft with the ''intention of flight'' until all such persons have disembarked, and in which a) a person is fatally or seriously injured, b) the aircraft sustains significant damage or structural failure, or c) the aircraft goes missing or becomes completely inaccessible. Annex 13 defines an aviation incident as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operation. A hull loss occurs if an aircraft is damaged beyond repair, lost, or becomes completely inaccessible. The first fatal aviation accident was the crash of a Rozière balloon near Wimereux, France, on June 15, 1785, killing the balloon's inventor, Jean-François Pilâtre de Rozier, and the other occupant, Pierre Romain.

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Go-around
In aviation, a go-around is an aborted landing of an aircraft that is on final approach or has already touched down. A go-around can either be initiated by the pilot flying or requested by air traffic control for various reasons, such as an unstabilized approach or an obstruction on the runway. Etymology The term arises from the traditional use of traffic patterns at airfields. A landing aircraft will first join the traffic pattern/circuit and prepare for landing. If for some reason, the pilot decides not to land, the pilot can simply fly back up to traffic pattern altitude/circuit height, and complete another circuit. The term "go-around" is still used even for modern airliners, though they may not use traditional traffic patterns/circuits for landing. Reasons for use Initiation of a go-around may be either ordered by air traffic control (normally the local or tower controller in a controlled field) or initiated by the pilot in command of the aircraft. In naval aviation, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2016 Magdalen Islands Mitsubishi MU-2 Crash
On 29 March 2016, a Mitsubishi MU-2 operated by Aero Teknic, a Canadian aircraft maintenance company, crashed on approach to Îles-de-la-Madeleine Airport, killing former Canadian politician Jean Lapierre, several members of his family, and the two pilots. Lapierre was flying to his father's funeral with his wife and three siblings. While one man survived the crash, he died of a heart attack after being pulled from the wreckage. Accident Before departure, Jean Lapierre mentioned that he was concerned about flying during bad weather. The aircraft left Montreal Saint-Hubert Longueuil Airport in Saint-Hubert, Quebec at 0931 Eastern Daylight Time and was headed to Îles-de-la-Madeleine Airport, on Havre-aux-Maisons island in the Magdalen Islands, also in Quebec. A little over two hours later (1230 Atlantic Daylight Time), the aircraft collided with terrain in Les Îles-de-la-Madeleine, Quebec, about short of the threshold of runway 07. At the time of the accident, there was light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
