g) With ‘LOAD?’ highlighted, again press the ENT
Key. The selected approach is added to the
flight plan as seen in Figure 7-33.

13) 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 will always
be displayed as white text, as in Figure 7-34.
Vertical guidance to the FAF and on to the
Missed Approach Point (MAP) is given using
the WAAS GPS altitude source, therefore, the
displayed altitude values are for reference
only.

14) 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 will be computed to maintain the -2.5 FPA.
To change the vertical flight path, perform the
following steps.
