radial

Konteksts: [..] Station declination. An alignment variation between the zero degree radial of a VOR and true north, determined at the time the VOR station is calibrated. [..]
Avots: Amendment 7 to the International Standards and Recommended Practices. Aerodromes. Annex 14, Volume I, to the Convention on International Civil Aviation

Definīcija:

The VOR system uses the phase relationship between a reference-phase and a rotating-phase signal to encode direction. The carrier signal is omni-directional and contains the amplitude modulated (AM) station Morse code or voice identifier. The reference 30 Hz signal is frequency modulated (FM) on a 9960 Hz sub-carrier. A second 30 Hz signal is derived from the electronic rotation of a directional antenna array 30 times a second. Although older antennas were mechanically rotated, current installations are scanned electronically to achieve the same result with no moving parts. When the signal is received in the aircraft, the FM signal is decoded from the sub carrier and the frequency extracted. The two 30 Hz signals are then compared to determine the phase angle between them. The phase angle is equal to the direction from the station to the airplane, in degrees from local magnetic north, and is called the "radial".
