GPS/SBAS TSO-C146a Class 3 Operation 

The GNS complies with AC 20-138A and has airworthiness approval for 
navigation using GPS and SBAS (within the coverage of a Satellite Based 
Augmentation System complying with ICAO Annex 10) for IFR en route, 
terminal area, and non-precision approach operations (including those 
approaches titled “GPS”, “or GPS”, and “RNAV (GPS)” approaches). The 
Garmin GNSS navigation system is composed of the GNS navigator and 
antenna, and is approved for approach procedures with vertical guidance 
including “LPV” and “LNAV/VNAV” and without vertical guidance including 
“LP” and “LNAV,” within the U.S. National Airspace System. 
 
The Garmin GNSS navigation system complies with the equipment 
requirements of AC 90-105 and meets the equipment performance and 
functional requirements to conduct RNP terminal departure and arrival 
procedures and RNP approach procedures without RF (radius to fix) legs. Part 
91 subpart K, 121, 125, 129, and 135 operators require operational approval 
from the FAA. 
 
The Garmin GNSS navigation system complies with the equipment 
requirements of AC 90-100A for RNAV 2 and RNAV 1 operations. In 
accordance with AC 90-100A, Part 91 operators (except subpart K) following 
the aircraft and training guidance in AC 90-100A are authorized to fly RNAV 2 
and RNAV 1 procedures. Part 91 subpart K, 121, 125, 129, and 135 operators 
require operational approval from the FAA.
