Note the altitude constraints associated with each
of the approach waypoints as seen in Figure 7-33.
These altitudes are loaded from the database and
are displayed as light blue text, indicating these
values are “designated” for use in computing
vertical deviation guidance.
If it is desirable not to use the displayed altitude
for calculating vertical deviation guidance, perform
the following:
a) Press the
FMS Knob to activate the cursor.
b) Turn the small FMS Knob to highlight the desired
altitude.
c) Press the
CLR Key.
d) Press the
FMS Knob to deactivate the cursor.
After making the altitude “non-designated”, it is
displayed as white text.
Altitude constraint values associated with the
Final Approach Fix (FAF) and waypoints beyond
the FAF cannot be designated for vertical
guidance. These altitude values are always
displayed as white text, as in Figure 7-34. Vertical
guidance from the FAF to the Missed Approach
Point (MAP) is given using the WAAS GPS altitude
source, therefore, the displayed altitude values
are for reference only.

As the aircraft approaches OPSHN, it may be
desirable to adjust how fast, or steep, the upcoming
descent will be. 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.
