  2. Altimeter - Wikipedia

    en.wikipedia.org/wiki/Altimeter

    Diagram showing the face of the "three-pointer" sensitive aircraft altimeter displaying an altitude of 10,180 ft (3,100 m). Reference pressure of about 29.92 inHg (1013 hPa) is showing in the Kollsman window. An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.

  3. Altimeter setting - Wikipedia

    en.wikipedia.org/wiki/Altimeter_setting

    It is designed to read zero at sea level in the vicinity of the aerodrome, unlike QNH which will not read precisely zero at sea-level. [2] Related to the altimeter settings are: TA [3] - Transition Altitude - altitude at which the pilot changes the aircraft's altimeter setting (usually from QNH) to standard pressure (1013.25 hPa)

  4. Pressure altimeter - Wikipedia

    en.wikipedia.org/wiki/Pressure_altimeter

    A chart showing how much the true altitude of an aircraft is below the altimeter reading ("indicated altitude") without correcting for temperature. The colder the ambient temperature, the lower the plane is — thus the saying "From hot to cold, look out below". [8] Modern aircraft use a "sensitive altimeter".

  5. Pressure altitude - Wikipedia

    en.wikipedia.org/wiki/Pressure_altitude

    It indicates altitude obtained when an altimeter is set to an agreed baseline pressure under certain circumstances in which the aircraft’s altimeter would be unable to give a useful altitude readout. Examples would be landing at a high altitude or near sea level under conditions of exceptionally high air pressure.

  6. Altitude - Wikipedia

    en.wikipedia.org/wiki/Altitude

    Indicated altitude is the reading on the altimeter when it is set to the local barometric pressure at mean sea level. In UK aviation radiotelephony usage, the vertical distance of a level, a point or an object considered as a point, measured from mean sea level ; this is referred to over the radio as altitude .(see QNH ) [ 2 ]

  9. Maximum elevation figure - Wikipedia

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    The MEF on Canadian VFR navigation charts is calculated by taking the higher value of: the top elevation of the highest obstacle plus the vertical accuracy (a variable number of feet) of the terrain source data; or; the elevation of the highest terrain plus 328 feet plus the vertical accuracy variable of the terrain source data.
