VOR LOC
Unless the VOR station is very close to the airport, you will not receive a valid VOR signal. However, you may be able to receive the localizer signal.
Flight Director
Turn on the F/Ds and push the VOR LOC mode selector switch. Tune the navigation control panel to the airport ILS frequency. The FMA shows VOR LOC and FD in green letters. This occurs if the ILS receiver receives a valid LOC signal. The F/D command does not show because there is no valid pitch mode. Push ALT HLD to activate a valid pitch mode. The FMA now also shows ALT HOLD and the F/D command shows on the AI. The F/D command may turn to command a turn to the localizer centerline.
Autopilot
Engage A/P A in CMD and push the VOR LOC mode selector switch. These annunciations show on the FMA if the ILS receiver has a valid localizer signal:
-VOR LOC in green letters (active)
-CMD
-CWS P.
The control wheel may turn to turn the airplane to the localizer centerline.
If the ILS receiver does not have a valid localizer signal, these show on the FMA:
-VOR LOC in white letters (armed)
-CMD
-CWS P
-CWS R.
