  2. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    The rule affected only those aircraft operating under IFR when in level flight above 3,000 ft above mean sea level, or above the appropriate transition altitude, whichever is the higher, and when below FL195 (19,500 ft above the 1013.2 hPa datum in the UK, or with the altimeter set according to the system published by the competent authority in ...

  3. Aeronautical chart conventions (United States) - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart...

    The charts are published "in accordance with Interagency Air Cartographic Committee specifications and agreements, approved by the Department of Defense and the Federal Aviation Administration". The legend of an aeronautical chart lists many of the symbols, colors and codes used to convey information to the map reader.

  4. Altimeter setting - Wikipedia

    en.wikipedia.org/wiki/Altimeter_setting

    In ISA temperature conditions the altimeter will read the height above the airfield/runway in the vicinity of the airfield. SPS/STD - 'Standard Pressure Setting' or just 'Standard' refers to the altimeter being set to the standard pressure of 1013.25 hPa. It is the setting that causes an altimeter to read the aircraft's flight level (FL).

  5. Aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart

    An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...

  6. Aeronautical Information Publication - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_Information...

    In aviation, an Aeronautical Information Publication (or AIP) is defined by the International Civil Aviation Organization as a publication issued by or with the authority of a state and containing aeronautical information of a lasting character essential to air navigation.

  7. Gillham code - Wikipedia

    en.wikipedia.org/wiki/Gillham_Code

    Gillham code is a zero-padded 12-bit binary code using a parallel nine-[1] to eleven-wire interface, [2] the Gillham interface, that is used to transmit uncorrected barometric altitude between an encoding altimeter or analog air data computer and a digital transponder.

  8. Sectional aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Sectional_aeronautical_chart

    Sectional charts are in 1:500,000 scale and are named for a city on the map. The Federal Aviation Administration (FAA) in the United States publishes over 50 charts covering the continental United States, Alaska, and Hawaii. Sectional charts are published by the National Aeronautical Navigation Services Group of the FAA.

  9. Height above ground level - Wikipedia

    en.wikipedia.org/wiki/Height_above_ground_level

    The altimeter, which is usually a barometer calibrated in units of distance instead of atmospheric pressure, can therefore be set in such a way as to indicate the height of the aircraft above ground. This is done by communicating with the control tower of the airport (to get the current surface pressure) and setting the altimeter so as to read ...
