The GNSS navigation system has [two ETSO-145 / TSO-C145a Class 3 approved Garmin GIA 63W and
GIA 63H units, and ETSO-146 / TSO-C146a Class 3 approved Garmin GDU 1XXX Display Units]. The
Garmin GNSS navigation system as installed in this aircraft complies with the equipment requirements
for PRNAV and BRNAV operations in accordance with AC 90-96A and JAA TGL-10 Rev 1. This does
not constitute an operational approval.
Garmin International holds an FAA Type 2 Letter of Acceptance (LOA) in accordance with AC 20-153
for database integrity, quality, and database management practices for the Navigation database. Pilots
and operators can view the LOA status at www.garmin.com > Aviation Databases > Type 2 LOA Status.
Navigation information is referenced to WGS-84 reference system.
GARMIN GNSS (GPS/SBAS) NAVIGATION SYSTEM LIMITATIONS
The pilot must confirm at system initialization that the Navigation database is current.
Navigation database is expected to be current for the duration of the flight. If the AIRAC cycle will
change during flight, the pilot 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 enroute, oceanic, and terminal navigation is prohibited unless the pilot 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. Contact
information to report Navigation database discrepancies can be found at
www.garmin.com > Support > Contact Garmin Support > Aviation. Pilots and operators can view
navigation data base alerts at www.garmin.com > In the Air > 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, [part number 006-A0154-01 (included in G1000 trainer software) version 3.00 or
later approved version with GARMIN GA36 and GA37 antennas selected], 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. This requirement is not necessary if SBAS coverage is
confirmed to be available along the entire route of flight. The route planning and WFDE prediction
program may be downloaded from the Garmin website on the internet. For information on using the
WFDE Prediction Program, refer to Garmin WAAS FDE Prediction Program, part number 190-00643-01,
'WFDE Prediction Program Instructions'.
For flight planning purposes, operations within the U.S. National Airspace System on RNP and RNAV
procedures when SBAS signals are not available, the availability of GPS integrity RAIM shall be
confirmed for the intended route of flight. In the event of a predicted continuous loss of RAIM of more
than five minutes for any part of the intended route of flight, the flight should be delayed, canceled, or re-
routed on a track where RAIM requirements can be met.
For flight planning purposes for operations within European B-RNAV and P-RNAV airspace, if more
than one satellite is scheduled to be out of service, then the availability of GPS integrity RAIM shall be
