Step-by-step: Set up an ILS approach

  1. Make the localizer 110.30 the active NAV frequency (swap it up from standby).

    ILS localizers live in the 108.10–111.95 MHz band on odd tenths.

  2. Set the course (CRS) to 040° — the final approach course.

    The course pointer must match the published final approach course for the deviation bar to make sense.

  3. Switch the CDI source to NAV1 (the localizer).

    Switching to LOC drops the autopilot lateral mode to ROL until you re-arm a mode.

  4. Arm APR mode to capture the localizer and glideslope.

    APR is the approach mode — it flies the ILS down to minimums.
