Instrument Rating
Instrument rating refers to the qualifications that a pilot must have in order to fly under instrument flight rules (IFR). It requires specific training and instruction beyond what is required for a private pilot certificate or commercial pilot certificate, including rules and procedures specific to instrument flying, additional instruction in meteorology, and more intensive training in flight solely by reference to instruments. Training and testing Testing consists of a written exam and a practical test (also known as a check ride in the US, or a flight test in other countries). The check ride is divided into an oral component (certain countries only) to verify that the applicant understands the theory of instrument flying and an actual flight to ensure the pilot possesses the practical skills required for safe IFR flight . For most private pilots, the most significant value of flying under IFR is the ability to fly in instrument meteorological conditions (such as inside cloud ...

Aviator
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators. In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots. Definition The first recorded use of the term ''aviator'' (''aviateur'' in French) was in 1887, as a variation of ''aviation'', from the Latin ''avis'' (meaning ''bird''), coined in 1863 by in ''Aviation Ou Navigation Aérienne'' ("Aviation or Air Navigation"). The term ''aviatrix'' (''aviatrice'' in French), now archaic, was formerly used for a female pilot. The term ''aviator'' (''aviateur'' ...

Pilot Licensing In Canada
Pilot licensing in Canada is administered by Transport Canada under the ''Aeronautics Act'' and the Canadian Aviation Regulations (CARs). Other than when flying a hang glider or paraglider, a person may only operate a Canadian-registered aircraft or act as a Aircrew member, flight crew member in Canada with a licence or permit issued by Transport Canada. At the end of 2008 there were 64,932 Canadian licences and permits held, giving Canada the second largest population of licensed pilots in the world. The first Canadian private pilot's licence was issued to James Stanley Scott on January 24, 1920, and the first Canadian transport licence was issued to Douglas G. Joy on April 1, 1939. Overview A licence is issued by Transport Canada in accordance with International Civil Aviation Organization (ICAO) licence Standards And Recommended Practices (SARPs). A ''licence'' can be used to fly domestically as well as internationally, while a ''permit'' does not comply with ICAO standard ...

Icing Conditions
In aeronautics, icing is the atmospheric icing, formation of water ice on an aircraft. Icing has resulted in numerous aviation accidents and incidents, fatal accidents in aviation history. Ice accretion and accumulation can affect the external surfaces of an aircraft – in which case it is referred to as ''airframe icing'' – or the aircraft engine, engine, resulting in carburetor icing, air inlet icing or more generically ''engine icing''. These phenomena may possibly but do not necessarily occur together. Not all aircraft, especially general aviation aircraft, are certified for ''flight into known icing'' (FIKI) – that is flying into areas with icing conditions certain or likely to exist, based on pilot reports, METAR, observations, and Terminal Aerodrome Forecast, forecasts. In order to be FIKI-certified, aircraft must be fitted with suitable ice protection systems to prevent accidents by icing. Definition Icing conditions exist when the air contains droplets of supercoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Stream
Jet streams are fast flowing, narrow thermal wind, air currents in the Earth's Atmosphere of Earth, atmosphere. The main jet streams are located near the altitude of the tropopause and are westerly winds, flowing west to east around the globe. The northern hemisphere and the southern hemisphere each have a polar jet around their respective polar vortex at around above sea level and typically travelling at around although often considerably faster. Closer to the equator and somewhat higher and somewhat weaker is a subtropical jet. The northern polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica. Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet. The El Niño–Southern Oscillation affects the location of the jet s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
METAR
METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting. Raw METAR is highly standardized through the International Civil Aviation Organization (ICAO), which enables it to be understood throughout most of the world. Report names In its publication the '' Aeronautical Information Manual'' (''AIM''), the United States Federal Aviation Administration (FAA) describes the report as ''aviation routine weather report'', while the international authority for the code form, the World Meteorological Organization (WMO), describes it as the ''aerodrome routine meteorological report.'' The National Oceanic and Atmospheric Administration (part of the United States Department of Commerce) and the United Kingdom's Met Office both employ the definition used by the FAA. METAR is also known as ''Meteorological Terminal Aviation Routine Weathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bárány Chair
The Barany chair or Bárány chair is a device used for aerospace physiology training, particularly for student pilots. Test The subject is placed in the swivel chair, blindfolded, then spun about the vertical axis while keeping their head upright or tilted forward or to the side. The subject is then asked to perform tasks such as determine their direction of rotation while blindfolded, or rapidly change the orientation of their head, or attempt to point at a stationary object without blindfold after the chair is stopped. The chair is used to demonstrate spatial disorientation effects, proving that the vestibular system is not to be trusted in flight. Pilots are taught that they should instead rely on their flight instruments. Uses The device is also used in motion sickness therapy. Nobel Prize The chair was named for Hungarian physiologist Robert Bárány, who used this device in his research into the role of the inner ear in the sense of balance. He won the 1914 Nobel Prize ...

Spatial Disorientation
Spatial disorientation is the inability to determine position or relative motion, commonly occurring during periods of challenging visibility, since visual system, vision is the dominant sense for orientation. The auditory system, vestibular system (within the inner ear), and proprioceptive system (sensory receptors located in the skin, muscles, tendons and joints) collectively work to coordinate movement with balance, and can also create illusory nonvisual sensations, resulting in spatial disorientation in the absence of strong visual cues. In aviation, spatial disorientation can result in improper perception of the Orientation (geometry), attitude of the aircraft, referring to the orientation of the aircraft relative to the horizon. If a pilot relies on this improper perception, this can result in inadvertent turning, ascending or descending. For aviators, proper recognition of aircraft attitude is most critical at night or in poor weather, when there is no visible horizon; in th ...

Sensory Illusions In Aviation
Human senses are not naturally geared for the in-flight environment. Pilots may experience disorientation and loss of perspective, creating illusions that range from false horizons to sensory conflict with instrument readings or the misjudging of altitude over water. Vestibular system The vestibular system, which is responsible for the sense of balance in humans, consists of the otolith organs and the semicircular canals. Illusions in aviation are caused when the brain cannot reconcile inputs from the vestibular system and visual system. The three semicircular canals, which recognize accelerations in pitch, yaw, and roll, are stimulated by angular accelerations; while the otolith organs, the saccule and utricle, are stimulated by linear accelerations. Stimulation of the semicircular canals occurs when the movement of the endolymph inside the canals causes movement of the crista ampullaris and the hair cells within them. Stimulation of the otolith organs occurs when grav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for ...
