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.
4) Press the APR Key.
If the following occurs, the flight director reverts to Roll Hold Mode (wings rolled level):
• Approach Mode is active and a Vectors-To-Final is activated
• Approach Mode is active and Navigation source is manually switched
• GPS Navigation Mode is active and the FAF is crossed after the automatic navigation source switch from
GPS to LOC
CHANGING THE SELECTED COURSE
The Selected Course on each PFD is controlled using the CRS1 and CRS2 knobs. 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.
