FMS Subsystem 2-27
COOL FEATURE
Automatic VOR Tuning †
"Auto-VLOC Tuning" can be selected from the Setup
page. When enabled, the FMS will automatically
tune the next down-path VOR in the active flight plan
into the primary nav frequency.
It may desirable to turn off this feature on one of the
IFDs in a dual installation to allow depiction of a
crossing radial for reference before crossing a VOR.
Also when navigating using airways, it may be
desirable to turn off this feature in order to check
navigation using off-airway VORs.
LATERAL OFFSETS
The system supports a capability to create and fly a lateral offset
from your flight plan. From the “FPL” tab of the FMS page with
the cursor around or above the active leg, press the “Offset
Route” LSK and use the right-hand knob on the IFD to dial in the
desired offset. Use the outer knob to change the value in 1nm
increments and the inner knob for 0.1nm increments. Turn the
knob left for left offsets and right for right offsets. Once the
intended offset has been entered, press the “Confirm Right/Left
x.x NM” LSK. At that point, the original LSK will indicate “Offset
Route Right/Left X.X NM”. To delete a lateral offset, press the
“Delete Offset” LSK. The maximum offset that can be dialed in is
20 NM. Lateral offsets are not available when in OBS mode.
Lateral offsets are unaffected by graphical route planning (“rubber
banding”) operations.
