APPENDIX D
For RAIM to work correctly, the GPS receiver must track at least five satellites. A minimum of six satellites is
required to allow RAIM to eliminate a single corrupt satellite from the navigation solution.
RAIM ensures that satellite geometry allows for a navigation solution calculation within a specified protection
limit (2.0 nm for oceanic and en route, 1.0 nm for terminal, and 0.3 nm for non-precision approaches). The
G1000 System monitors RAIM and issues an alert message when RAIM is not available (see Appendix A).
Without RAIM, GPS position accuracy cannot be monitored. If RAIM is not available when crossing the FAF,
the pilot must fly the missed approach procedure.
W
HY ARE THERE NOT ANY APPROACHES AVAILABLE FOR A FLIGHT PLAN
Approaches are available for the final destination airport in a flight plan or as a direct-to (keep in mind
that some VOR/VORTAC identifiers are similar to airport identifiers). If a destination airport does not have a
published approach, the G1000 indicates "NONE" for the available procedures.

HAT HAPPENS WHEN AN APPROACH IS SELECTED
?
ARRIVAL BE STORED
When an approach, departure, or arrival is loaded into the active flight plan, a set of approach, departure,
or arrival waypoints is inserted into the flight plan, along with a header line showing the title of the selected
instrument procedure. The original en route portion of the flight plan remains active, unless the instrument
procedure is activated. This may be done either when the procedure is loaded or at a later time.
Flight plans can also be stored with an approach, a departure, or an arrival. Note that the active flight plan
is erased when the system is turned off. Also, the active flight plan is overwritten when another flight plan is
activated. When storing flight plans with an approach, a departure, or an arrival, the G1000 uses the waypoint
information from the current database to define the waypoints. If the database is changed or updated, the
G1000 System automatically updates the information, provided the procedure has not been modified. Should
an approach, departure, or arrival procedure no longer be available, the flight plan becomes locked until the
procedure is deleted from the flight plan.
C " G " ("/G")
AN SLANT OLF
"/G" may be filed for a flight plan. The G1000 System meets the requirements of TSO-C145a Class 3 and
ETSO-C145 Class 3 installations. GPS approaches are not to be flown with an expired database. See the
approved AFM/POH as well as the Aeronautical Information Manual (AIM) for more information.
W OBS S
HAT DOES THE
The OBS Softkey is used to select manual sequencing of waypoints. Activating OBS mode sets the current
active-to waypoint as the primary navigation reference and prevents the system from sequencing to the next
waypoint in a flight plan. When OBS mode is cancelled, automatic waypoint sequencing is continued, and
the G1000 automatically activates the next waypoint in the flight plan once the aircraft has crossed the present
active waypoint.
