Using The Vnav Feature - Garmin GDU 37X Pilot's Manual

At 200 ft above the target altitude, the "Approaching Target Altitude" message
appears, the 'Estimated Time To VNAV' goes blank, and the VNAV indicator disappears
from the HSI.
CAUTION: The GDU 37X and the VNAV function are only VFR navigation aids
and are not intended for instrument approaches.

USING THE VNAV FEATURE

Use the VNAV (Vertical Navigation) feature to ensure the aircraft is at the proper
altitude. The VNAV Indicator appears on the HSI (when displayed) as a horizontal light
blue bar. A message appears when approaching the VNAV Profile. When the bar is in
the vertical center of the HSI, the aircraft is at the proper altitude for the VNAV Profile.
Configuring a VNAV profile:
1) While navigating a flight plan or direct-to, press the FPL Key.
2) Turn the FMS Joystick to select the Vertical Navigation Page.
3) Press the FMS Joystick to activate the cursor.
4) Enter the desired profile into the fields, and press the EXIT Softkey.
