SECTION 7 – NAVIGATION
f) Press the eNT Key. The cursor is now displayed in
the VNV offset field as shown in Figure 7-28.
Figure 7-28 enter VNV Offset Distance
g) Enter the offset, or distance from the waypoint
at which the selected altitude will be reached. In
this case, three miles prior to OPSHN is entered.
In other words, the G1000 gives vertical guidance
so the aircraft will arrive at an altitude of 10,000
feet three miles prior to OPSHN.
h) Press the eNT Key twice to activate the direct-to.
Note, in Figure 7-29, the magenta arrow in the
Active Flight Plan Window indicating the direct-to
OPSHN after the offset waypoint for OPSHN. The
preceding offset waypoint indicates the offset
distance and altitude that was previously entered.
The remaining waypoints in the loaded arrival
procedure have no database specified altitudes,
therefore, dashes are displayed. Keep the CDI
centered and maintain a track along the magenta
line to OPSHN.
Note the Direct-to waypoint is within the loaded
arrival procedure, therefore, phase of flight scaling
for the CDI changes to Terminal Mode and is
annunciated by displaying 'TERM' on the HSI.

NOTe: If the loaded arrival procedure has
waypoints with altitude constraints retrieved
from the database, those altitudes are displayed
as white numerals. This indicates the altitudes will
not be used by the system for vertical guidance
until manually accepted by the pilot. To accept
the displayed altitude, place the cursor over the
altitude and press the eNT Key. The altitude entry
then changes to light blue numerals, indicating
the altitude will now be used by the system for
providing vertical guidance.
Figure 7-29 Direct-to Active
12) The aircraft is proceeding to OPSHN. The expected
approach is the RNAV LPV approach to runway 35R,
so it is selected.
a) Press the PROC Key to display the Procedures
Window.
If the GPS system is not WAAS capable, or WAAS
is not available, the LPV approach will not be
displayed in the list of available approaches.
Selecting the LNAV approach for runway 35R gives
vertical guidance up to the IAF.
