VOR LOC Mode
Pushing the VOR LOC switch selects VOR mode if a VOR frequency is
tuned or selects LOC mode if a localizer frequency is tuned.
The VOR mode provides roll commands to track the selected VOR course.
The LOC mode provides roll commands to track the selected localizer
course along the inbound front course bearing.
The selected course can be intercepted while engaged in
- LNAV
- HDG SEL
- CWS R if an autopilot is engaged in CMD.
The capture point is variable and depends on intercept angle and closure
rate. Localizer capture occurs not later than 1/2 dot deviation. Course
capture is indicated when VOR/LOC annunciation changes from armed to
engaged.
