Flying a Flight Plan/GPS Course
NOTE: Changing the navigation source cancels
Navigation Mode and causes the flight director
to revert back to Roll Hold Mode (wings rolled
level).
As the aircraft closes on Salina VOR, GPS is used to
navigate the next leg, airway V244. The aircraft is cur-
rently tracking inbound on Airway V4.
Flying a GPS flight plan:
1) Enter Salina VOR (SLN) into the GPS flight plan.
2) Transition from VOR to GPS Navigation Mode:
a) Press the
CDI Softkey until GPS is the selected
navigation source. Due to VOR signal loss,
VOR Navigation Mode is cancelled. The ‘VOR’
annunciation flashes yellow.
Flashes up to 10 sec, Transitions to Roll Hold
Mode Unless NAV Key is Pressed

b) Press the NAV Key to activate GPS Navigation
Mode. The autopilot guides the aircraft along
the active flight plan leg.
If the NAV Key is not pressed within 10 seconds
of VOR signal loss, the flight director reverts to
Roll Hold Mode (wings rolled level).
3) Following the flight plan, the autopilot continues
to steer the aircraft under GPS guidance. Note that
in GPS Navigation Mode, course changes defined
by the flight plan are automatically made without
pilot action required.
