Modes of Operation
BACK COURSE (BC) MODE
The BC mode automatically intercepts, captures, and tracks the back
course localizer signal, as shown in figure 8--15. When flying a back
course localizer approach, glideslope capture is automatically inhibited.
The BC mode is set up and flown similar to a front course localizer
approach. The BC procedure is described in table 8--5.
