  2. Position error - Wikipedia

    en.wikipedia.org/wiki/Position_error

    In an ideal static system the air pressure fed to the altimeter and airspeed indicator is equal to the pressure of the air at the altitude at which the aircraft is flying. As the air flows past an aircraft in flight, the streamlines are affected by the presence of the aircraft, and the speed of the air relative to the aircraft is different at ...

  3. Air data inertial reference unit - Wikipedia

    en.wikipedia.org/wiki/Air_data_inertial...

    An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and attitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...

    en.wikipedia.org/wiki/Air_data_computer

    The Bendix Central Air Data Computer contains complex electromechanical mechanisms. Electrical-mechanical air data computers were developed in the early 1950s to provide a central source of airspeed, altitude, and other signals to avionic systems that needed this data.

    Altimeter reading when subscale set 1013.25 hPa (atmospheric pressure at sea level in the International Standard Atmosphere) [2] QNH The pressure set on the subscale of the altimeter so that the instrument indicates its height above sea level (the altimeter will read runway elevation when the aircraft is on the runway).

  6. Pitot–static system - Wikipedia

    en.wikipedia.org/wiki/Pitot–static_system

    Pressure altimeters must be calibrated prior to flight to register the pressure as an altitude above sea level. The instrument case of the altimeter is airtight and has a vent to the static port. Inside the instrument, there is a sealed aneroid barometer. As pressure in the case decreases, the internal barometer expands, which is mechanically ...

  7. Altimeter setting - Wikipedia

    en.wikipedia.org/wiki/Altimeter_setting

    QFE - is the barometric altimeter setting that causes an altimeter to read zero when at the reference datum of a particular airfield (in practice, the reference datum is either an airfield center or a runway threshold). In ISA temperature conditions the altimeter will read the height above the airfield/runway in the vicinity of the airfield.

    A source close to the couple told PEOPLE earlier this month that Belichick will "put his all into the new coaching job," and that he "needed to get back to work" after parting ways with the New ...

  9. Ground proximity warning system - Wikipedia

    en.wikipedia.org/wiki/Ground_proximity_warning...

    The system monitors an aircraft's height above ground as determined by a radar altimeter. A computer then keeps track of these readings, calculates trends, and will warn the flight crew with visual and audio messages if the aircraft is in certain defined flying configurations ("modes").
