As the aircraft approaches OPSHN, it may be desirable to adjust the speed, or steepness of the upcoming

descent. The default Flight Path Angle (FPA) is -2.5 degrees and a required vertical speed is computed to
maintain the -2.5 FPA. To change the vertical flight path, perform the following steps.

a)

Press the VNV PROF Softkey to place the cursor in the target vertical speed field (VS TGT) as shown in Figure
5-124.

b)

At this point, the descent vertical speed can be selected, or the FPA can be selected. Turn the large FMS Knob
to select the desired selection field, then turn the small

FMS Knob to enter the desired value.

Note the information now displayed in the ‘CURRENT VNV PROFILE’ box. Also, note the offset waypoint (orange
box) and gray circle are now displayed on the map. The gray circle marks the Top of Descent (TOD). In this
example, vertical guidance is provided at the TOD that results in a -3.0 degree FPA descent to an altitude of
10,000 feet upon reaching the offset waypoint.
