The FMS Course function will always be armed (i.e. it will always
intercept the flight plan) in a To intercept. If the airplane is in a
From course, it will intercept only if the dialed course trajectory
intercepts the flight plan. If the dialed course does not intercept
the flight plan, the airplane will fly that course indefinitely.
The FMS Course function will be exited when the airplane
intercepts the active waypoint in a To intercept or when
intercepting a downpath leg in the From case. Pressing the nav
source knob while the FMS course function is active will also
cancel the FMS Course mode and return to GPS as the active
nav source mode. The FMS Course will remain active if a From
course is dialed and the airplane does not intercept the FPL.
VLOC Method
†
If the Nav Source knob is set to VLOC as the active nav mode
and a VOR station is tuned and received, then use the external
course knob on the CDI/HSI/EFIS/etc to set the desired inbound
or outbound radial as required.
DELETING A FLIGHT PLAN
Select the “Routes” tab of the FMS page. Use the bottom right
AeroNav knob to scroll to the desired flight plan in the list or touch
the flight plan to hig
hlight the route. Press the “CLR” button on
the bezel and a green confirm dialog box pops up. Press “Enter”
or “Cancel” LSKs or use the bezel “ENTR” or “CLR” buttons to
finish the deletion.
CREATING A HOLDING PATTERN
A hold can be put on any waypoint that has a fix terminated leg
–
waypoints that terminate with a lat/lon position such as navaids,
enroute waypoints, user waypoints, airports, etc. Legs that
terminate at an altitude, DME distance, radial crossings, etc. do
not support attaching a hold. Hold fixes are always fly-over
waypoints and not fly-by waypoints.
Use the edit cursor on the flight plan to select the waypoint of
interest, then push the bottom right AeroNav knob or touch the
desired location to display a drop down list of options. Near the
top of that list, you will see “Hold at <waypoint name>”. Scroll to
highlight that drop down list entry and push the knob again. You
have just added a holding leg, populated with standard hold data.
