Avionics VOR/ILS (Option 302)
Using VOR [VHF Omnidirectional Range] Softkeys
To set the VOR bearing direction as From or To
1. Press Aux Fctn > Avionics > VOR
2. Press Bearing
3. Press Direction
(Default selection is From.)
4. Select either From | To
From - In the From convention, the VOR transmitter beacon is made the
reference point and the Bearing Angle is between local magnetic-North and
the beacon-to-aircraft radial line (RL).
To - In the To convention, the aircraft is made the reference point and the
Bearing Angle is between local magnetic-North and the aircraft-to-beacon
radial line (RL).
RL(To) = 180° – RL(From)
To set the frequency of the reference signal (REF Freq) and the
variable phase signal (VAR Freq)
1. Press Aux Fctn > Avionics > VOR
2. Press REF/VAR
3. Press REF/VAR Freq
(Default value is 30 Hz.)
4. Select a value in Hz | kHz | MHz | GHz from 10 to 60 Hz.
Enter a value in Hz to set the frequency of the reference signal (REF Freq) and
the variable phase signal (VAR Freq).
To set the amount of FM deviation that the 30 Hz reference signal
(REF Freq) applies on the sub-carrier
1. Press Aux Fctn > Avionics > VOR
2. Press REF/VAR
3. Press REF Deviation
(Default value is 480 Hz.)
4. Select a value in Hz | kHz | MHz | GHz from 0 Hz to 1 kHz.
Enter a value in Hz to set the amount of FM Deviation that the 30 Hz reference
signal (REF Freq) applies on the sub-carrier.
The 30 Hz reference signal (REF Freq) is placed on a sub-carrier of 9960 Hz
(SubCarrier Freq) using frequency modulation with a peak deviation set to
480 Hz (REF Deviation). This frequency modulated sub-carrier is then
