curved path to turn the aircraft on course. That
curved path will be depicted on the map.
ENTERING AND INTERCEPTING A RADIAL
FMS Method
The FMS Course function will allow the pilot to navigate “To” or
“From” the active waypoint while OBS is selected as the nav
source. Press the Nav Source knob to make OBS the active nav
mode and then adjust the FMS (OBS) course using the external
course adjust knob (i.e. course set knob on a CDI or HSI or
EFIS). If there is no installed external course setting device, then
turn the IFD nav source knob to adjust the FMS Course value.
For IFDs without a nav source knob (e.g. IFD510) the course can
be adjusted by turning the inner knob, but
only on a page under
the Map subsystem .
FMS Course mode makes the current waypoint act like a VOR.
Select the desired radial to fly inbound or outbound. Adjusting the
course to or from the active waypoint will be reflected by the
To/From flag as in a traditional HSI. The course deviation
indicator will be presented in relation to the selected course.
As the FMS course is adjusted, the course will be shown in the
upper right corner of the IFD (as part of the nav source), and the
