Inserting Terminal Procedures and Approaches
After creating your flight plan, you can select an approach, departure, or arrival procedure so the GNS 480 can
guide you through the flight plan. You may also make adjustments in Flight Edit mode.
1. Press the PROC function smart key for Procedure Mode. The Origin and Destination waypoint of your
active flight plan are shown.
2. Press the Depart menu item smart key to select the Departure procedure. If available, select the
departure runway (with the Small knob or the menu item keys).
3. Turn the Large knob to highlight the transition and turn the Small knob to make the selection. Press
Menu/Enter to accept the selections.
4. Press the BACK function smart key to return to the Procedures mode. Depending on the procedure for
your destination, press the Destination Arrival or Appch menu item smart key.

choices with the Small knob. Press Menu/Enter to accept the procedure.
6. If desired, select an alternate airport by pressing the Alternate Select menu item key.
7. Press EXEC to activate the procedures for your flight plan.
Perform a RAIM Prediction
RAIM prediction predicts if GPS coverage is available for any waypoint. This is used when WAAS satellites or
corrections are not available. If WAAS corrections are not available, vertical guidance will not be available for
an approach.
1. Highlight a waypoint in the active flight plan or select a waypoint from the database. Press INFO and
then press the RAIM function smart key when it is shown.
2. Press the CRSR knob in. One of the fields will be highlighted. Change the values of the Arrival Date
and/or Arrival Time (in UTC time) with the Small knob while moving to a value with the Large knob.
The default calculation is the ETA to the last waypoint in the active flight plan. When selecting a
waypoint from the database other than one in the active flight plan, the default calculation is the ETA
from the present position to the waypoint.
3. After setting the values, press the Menu/Enter key to compute the RAIM prediction.
