GPS NAVIGATION
8) Turn the small FMS Knob to display a list possible VNAV profile endpoints. When using a flight plan, the target
reference waypoint itself can be specified from the waypoints contained in the flight plan. By default, the last
waypoint in the flight plan is selected. Highlight the desired waypoint.
9) Press the ENT Key.
10) With the ‘TARGET ALTITUDE’ field highlighted, select the target altitude. If the selected altitude is above the
current aircraft altitude, a profiled climb is created. If the selected altitude is below the current aircraft altitude,
a profiled descent will be created.
11) Press the ENT Key. The cursor is now placed in the ‘TARGET VERTICAL SPEED’ field. The default profile utilizes
a 400 foot-per-minute descent rate.
12) To change the vertical speed, enter the desired vertical speed.
13) Press the ENT Key when finished.
With the profile set, the vertical speed required (VSR) and ‘Begin Climb In’ or ‘Begin Descent In’ time is
displayed. Expect the following to occur when using the vertical navigation feature:
At one minute prior to reaching the Bottom Of Climb or Top Of Descent point (gray arc), the message
‘APPR VPROF - Approaching VNAV Profile’ is displayed as a PFD alert (Figure 5-81). The descent (or climb)
angle also locks to prevent changes in speed from altering the profile. If selected, the vertical speed required
(VSR) readout on the default NAV and map pages shows the desired vertical speed to maintain the proper
descent (or climb) angle. At 500 feet above (or below, for a climb) the target altitude (white arc), an ‘APPR TRG
ALT’ - Approaching Target Altitude (Figure 5-82) message is provided. The VSR readout on the Navigation Map
Page is blanked out at this point.

NOTE: The VNAV mesages (Figures 5-81 and 5-82) will only be displayed if the VNAV messages are enabled.
Press the MENU key on the VNAV Page to enable or disable the messages.
