SYSTEM OVERVIEW
Because of the tighter protection limit on approaches, there may be times when RAIM is not available. The
G1000 automatically monitors RAIM and warns with an alert message when it is not available. If RAIM is not
predicted to be available for the final approach course, the approach does not become active, as indicated by
the messages “Approach is not active” and “RAIM not available from FAF to MAP”. If RAIM is not available
when crossing the FAF, the missed approach procedure must be flown.
Predicting RAIM availability at a selected waypoint
1) Select the GPS Status Page.
2) If necessary, select the RAIM Softkey.
3) Press the FMS Knob . The ‘WAYPOINT’ field is highlighted.
4) Turn the small FMS Knob to display the Waypoint Information Window.
5) Enter the desired waypoint:
a) Use the FMS Knob to enter the desired waypoint by identifier, facility, or city name and press the ENT Key. Refer
to Section 1.7 for instructions on entering alphanumeric data into the G1000.
Or:
a) Turn the small FMS Knob counter-clockwise to display a list of flight plan waypoints (the FPL list is populated
only when navigating a flight plan).
b) Turn the small FMS Knob clockwise to display the NRST, RECENT, or AIRWAY waypoints, if required.
c) Turn the large FMS Knob clockwise to select the desired waypoint. The G1000 automatically fills in the identifier,
facility, and city fields with the information for the selected waypoint.

6) Use the FMS Knob to enter an arrival time and press the ENT Key.
