LOC Approach Mode allows the autopilot to fly a LOC/ILS approach with a glideslope. When LOC Approach
Mode is armed, Glideslope Mode is also armed automatically. LOC captures are inhibited if the difference
between aircraft heading and localizer course exceeds 105°.
Selecting LOC Approach Mode:
1) Ensure a valid localizer frequency is tuned.
2) Ensure that LOC is the selected navigation source (use the CDI Softkey to cycle through navigation sources if
necessary).
3) Press the APR Key.
Or:
1) Ensure that GPS is the selected navigation source (use the CDI Softkey to cycle through navigation sources if
necessary).
2) Ensure a LOC/ILS approach is loaded into the active flight plan.
3) Ensure the corresponding LOC frequency is tuned.

CHANGING THE SELECTED COURSE
The Selected Course is controlled using the CRS Knob (while in VOR, LOC, or OBS Mode). Pressing the
CWS Button and hand-flying the aircraft does not change the Selected Course while in Approach Mode.
The autopilot guides the aircraft back to the Selected Course (or GPS flight plan) when the CWS Button is
released.
