GARMIN GNSS (GPS/SBAS) NAVIGATION SYSTEM LIMITATIONS
The flight crew must confirm at system initialization that the navigation database is current. The
navigation database is expected to be current for the duration of the flight. If the AIRAC cycle will
change during flight, the flight crew must ensure the accuracy of navigation data, including suitability of
navigation facilities used to define the routes and procedures for flight. If an amended chart affecting
navigation data is published for the procedure, the database must not be used to conduct the procedure.
GPS/SBAS based IFR en route, oceanic, and terminal navigation is prohibited unless the flight crew
verifies and uses a valid, compatible, and current navigation database or verifies each waypoint for
accuracy by reference to current approved data.
Discrepancies that invalidate a procedure must be reported to Garmin International. The affected
procedure is prohibited from being flown using data from the navigation database until a new navigation
database is installed in the aircraft and verified that the discrepancy has been corrected. Navigation
database discrepancies can be reported at
FlyGarmin.com then select ―Aviation Data Error Report.‖
Flight crew and operators can view navigation database alerts at FlyGarmin.com then select ―NavData
Alerts.‖
For flight planning purposes, in areas where SBAS coverage is not available, the pilot must check RAIM
availability.
Within the United States , RAIM availability can be determined using the Garmin WFDE
Prediction program, Garmin part number 006-A0154-03 (included in GNS trainer) software
version 3.00 or later approved version with Garmin approved antennas, or the FAA‘s en route
and terminal RAIM prediction website:
www.raimprediction.net , or by contacting a Flight
Service Station.
Within Europe , RAIM availability can be determined using the Garmin WFDE Prediction
program or Europe‘s AUGER GPS RAIM Prediction Tool at
http://augur.ecacnav.com/augur/app/home .
For other areas , use the Garmin WFDE Prediction program.
