The G1000 checks every knob, softkey and entry as you make it, and tells you when something was accepted but wrong.

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 108.10โ€“111.95 MHz band on odd tenths.

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

    Switching to LOC drops the autopilot lateral mode to ROL until you re-arm a mode. It also has to come first: on GPS the unit sets the course pointer itself and the CRS knob does not move it.

  3. Set the course (CRS) to 040ยฐ โ€” the final approach course.

    The course pointer must match the published final approach course for the deviation bar to make sense. On a VOR or localizer source the CRS knob is yours to set.

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

    APR is the approach mode โ€” it flies the ILS down to minimums.
