Applicable to dual installations consisting of two GTNs: The Garmin GNSS navigation system, as
installed in this aircraft, has been found to comply with the requirements for GPS Class II oceanic and
remote navigation (RNP-10) without time limitations in accordance with AC 20-138A and FAA Order
8400.12A. The Garmin GNSS navigation system can be used without reliance on other long-range
navigation systems. This does not constitute an operational approval.
Applicable to dual installations consisting of two GTNs: The Garmin GNSS navigation system, as
installed in this aircraft, has been found to comply with the navigation requirements for GPS Class II
oceanic and remote navigation (RNP-4) in accordance with AC 20-138A and FAA Order 8400.33. The
Garmin GNSS navigation system can be used without reliance on other long-range navigation systems.
Additional equipment may be required to obtain operational approval to utilize RNP-4 performance. This
does not constitute an operational approval.
The Garmin GNSS navigation system, as installed in this aircraft, complies with the accuracy, integrity,
and continuity of function, and contains the minimum system functions required for P-RNAV operations
in accordance with JAA Administrative & Guidance Material Section One: General Part 3: Temporary
Guidance Leaflets, Leaflet No 10 (JAA TGL-10 Rev 1). The GNSS navigation system has [one or more]
TSO-C146c Class 3 approved Garmin GTN 625/635/650 Navigation Systems. The Garmin GNSS
navigation system as installed in this aircraft complies with the equipment requirements for
P-RNAV and B-RNAV/RNAV 5 operations in accordance with AC 90-96A CHG 1 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. Flight

For installations outside the United States of America or in non-U.S. registered aircraft, installations
should comply with applicable regulations and guidance of the cognizant Civil Aviation Authority.
Note that for some types of aircraft operation and for operation in non-U.S. airspace, separate operational
approval(s) may be required in addition to equipment installation and airworthiness approval.
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 en route, 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.
