FLIGHT DIRECTOR LATERAL MODES (Cont)
B/C MODE
The localizer/back course mode can be selected by pushing the B/C button on the FGP. Back course mode can be deselected
in one of the following ways:
- Pressing the B/C button again
- Selecting another lateral mode
- Changing the frequency of the navigation signal
- Changing the preselect navigation source (other than changing to localizer)
Back course mode generates the command to capture and track the back course signal from the selected LOC source, dis-
played on the PFD. Upon back course mode selection, the flight director will arm to capture the signal from the selected
nav source. If the flight director is in nav mode capturing/tracking FMS (with the LOC as preselect source) it will continue
to track FMS and arm for LOC capture.
Back course capture clears half bank and heading modes. Back course mode is annunciated on the PFD with two messages:
green in the lateral capture field indicating captured NAV source and also green in the lateral arm field, which identifies
the armed NAV source (B/C1 or B/C2).
