Exercise 6.7: Vertical Navigation (VNAV)
1. Where does one go to program a VNAV flight plan on the G1000?
In the flight plan, assign VNAV target altitudes to programmed waypoints for enroute
and descent phases of flight. Altitudes may also be loaded from the database. The G1000
calculates Top Of Decent (TOD) and Bottom Of Decent (BOD) based on ground speed.
2. Are any VNAV messages provided to the pilot?
TOD and BOD message are displayed in the PFD Navigation Data Box.
3. Are visual references for VNAV operations shown on the moving map?
A gray hollow dot is placed at the calculated TOD along the flight path; a white hollow
dot is used to represent the BOD.
4. How do you verify the GFC 700 autopilot is correctly moded to capture the current VNAV
profile?
After pressing the VNV Key, verify that ‘VPTH’ is annunciated in the AFCS Status Box
on the PFD. White annunciations represent armed modes; active modes are shown in
green.
5. How do you cancel a VNAV profile?
Press the CNCL VNAV Softkey on the Active Flight Plan Page or use the “Cancel VNAV”
menu option. The G1000 still follows the active flight plan, but stops vertical navigation.
