  2. Aircraft compass turns - Wikipedia

    en.wikipedia.org/wiki/Aircraft_compass_turns

    The standard practice when flying with a gyro-stabilized compass (or heading indicator) is to read the magnetic compass only while in straight and level unaccelerated flight. This reading is then used to set the gyro-stabilized compass. The gyro compass will read correctly in a turn, whereas the magnetic compass can't be read properly while ...

  3. Automatic direction finder - Wikipedia

    en.wikipedia.org/wiki/Radio_Magnetic_Indicator

    On aviation ADFs, the unit automatically moves a compass-like pointer (RMI) to show the direction of the beacon. The pilot may use this pointer to home directly towards the beacon, or may also use the magnetic compass and calculate the direction from the beacon (the radial ) at which their aircraft is located.

  4. Air navigation - Wikipedia

    en.wikipedia.org/wiki/Air_navigation

    A general aviation (GA) pilot will often make use of either a flight computer – a type of slide rule – or a purpose-designed electronic navigational computer to calculate initial headings. The primary instrument of navigation is the magnetic compass.

  5. Heading (navigation) - Wikipedia

    en.wikipedia.org/wiki/Heading_(navigation)

    6 - Magnetic variation, caused by variations in Earth's magnetic field. 7 - Compass heading or compass course, before correction for magnetic deviation or magnetic variation. 8 - Magnetic heading, the compass heading corrected for magnetic deviation but not magnetic variation; thus, the heading reliative to magnetic north.

  6. Flight instruments - Wikipedia

    en.wikipedia.org/wiki/Flight_instruments

    The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.

  7. Heading indicator - Wikipedia

    en.wikipedia.org/wiki/Heading_indicator

    Some more expensive heading indicators are "slaved" to a magnetic sensor, called a flux gate. The flux gate continuously senses the Earth's magnetic field, and a servo mechanism constantly corrects the heading indicator. [4] These "slaved gyros" reduce pilot workload by eliminating the need for manual realignment every ten to fifteen minutes.

  8. Compass - Wikipedia

    en.wikipedia.org/wiki/Compass

    A modern military compass, with included sight device for aligning. A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north.

  9. 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 altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...
