The “Approaching VNAV Profile” message appears one minute prior to the initial
descent point. The descent angle locks to prevent changes in speed from altering the
profile. The VNAV feature does not take into account any changes in groundspeed that
occur during the transition from level flight to descent or climb.
At 500 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 aera 795/796 is a VFR navigation tool and should not be used
to perform instrument approaches.
CAUTION:
VNAV is only a VFR navigation aid and is 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 teal
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.
