Radio Navigation Setup

Step-by-step: Radio Navigation Setup

1. Set up your route first. Type EGLL/LFPG and press 1R.
2. Navigate to the RAD NAV page to set up navigation radios.

   The RAD NAV page lets you manually tune VOR, ILS, and ADF frequencies. While the FMS auto-tunes navaids along your route, pilots manually set and verify frequencies as a crosscheck — especially the ILS for the approach.

3. Enter the Dover VOR identifier. Type DVR and press 1L. The MCDU will look up the identifier.

   Dover VOR (DVR, 114.95 MHz) is on the white cliffs of Dover — one of the most-used navaids in European aviation. You find VOR identifiers and frequencies on en-route charts and your flight plan. Entering the ident auto-tunes the frequency.

4. Now enter the Dover VOR frequency 114.95. Type 114.95 and press 1L.

   Every VOR has a unique frequency published on aeronautical charts. VOR frequencies range from 108.00 to 117.95 MHz. You can enter either the identifier or the frequency — both work. In practice, the FMS auto-tunes VORs along your route, but pilots verify as a crosscheck.

5. Set up the ILS for your approach. Enter ILS frequency 110.70 for Paris CDG runway 27L. Type 110.70 and press 3L.

   ILS frequencies come from the approach plate for your destination runway. You look up the Jeppesen or national AIP approach chart for runway 27L at LFPG, which publishes the localizer frequency (110.70), course (268°), and glideslope details. Getting this wrong means you could intercept the wrong localizer beam or get no signal at all during approach — extremely dangerous in low visibility.

6. Radio navigation is configured. Press INIT to return to the main page.
