  2. Aircraft compass turns - Wikipedia

    en.wikipedia.org/wiki/Aircraft_compass_turns

    Compass turns (turns using the magnetic compass as the primary reference instrument) are not standard practice in modern aircraft. Compass turns are typically performed in simulated or actual failures of the directional gyro or other navigational instruments. A magnetic compass is a simple instrument when the compass is not moving and is on the ...

  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.

    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. 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.

  7. Air navigation - Wikipedia

    en.wikipedia.org/wiki/Air_navigation

    The primary instrument of navigation is the magnetic compass. The needle or card aligns itself to magnetic north, which does not coincide with true north, so the pilot must also allow for this, called the magnetic variation (or declination). The variation that applies locally is also shown on the flight map.

  9. Aviation and Transportation Security Act - Wikipedia

    en.wikipedia.org/wiki/Aviation_and...

    The Act created the Transportation Security Administration (TSA). [1] However, with the passage of the Homeland Security Act in 2002, the TSA was later transferred to the Department of Homeland Security. [2] The legislation (S. 1447) was sponsored by Democratic Senator Fritz Hollings from South Carolina and co-sponsored by 30 other senators.
