GPS Receiver
Reference
• At one minute prior to the initial descent point, a
message ‘Approaching VNAV Profile’ occurs. The
time to vertical navigation (‘Time to VNV’) will
sequence from indicating time to initial descent
point to indicating time to reach target altitude.
Finally, the descent angle will lock to prevent
changes in speed from altering the profile.
• At 500 feet above the target altitude, an ‘Approach-
ing Target Altitude’ message is provided. The time
to vertical navigation (‘Time to VNV’) figure will go
blank and the VNAV indicator will disappear from
the HSI Page.
WARNING: GPS accuracy may be degraded
by the U.S. Department of Defense-imposed
Selective Availability (SA) program. With SA
on, GPS altitude may be in error by several
hundred feet. Errors of this magnitude may
result in fluctuations in the VNAV indicator on
the HSI Page. The NavTalk Pilot is a VFR
navigation tool and should not be used to
perform instrument approaches.
