NO.: 1107 Revision A
TO: Owners and Operators of all Garmin Aviation Products using a Terrain
Database
DATE: March 01, 2011
SUBJECT: Anomalies in Greenland Terrain Data May Inhibit Operational Capability
AFFECTED PRODUCTS
All Garmin aviation products that use a Terrain Database (listed below):
•GNS 400W/500W and legacy GNS 400/500 series products
•GPSMAP 296/396/495/496/695/696/aera handheld products
•G3X/G300 systems
•G500/G500H/G600 systems
•G1000, G900X, G950, Cirrus Perspective™, and Embraer Prodigy™ systems
DESCRIPTION
Areas of poor terrain data quality in Greenland (as described in Terrain Data Alert dated
March 01, 2011) may adversely affect the TAWS/Terrain Alerting, ESP (Electronic
Stability Protection), and SVT (Synthetic Vision Technology) functions listed below.
•TAWS/Terrain Alerting – May result in nuisance alerts when approaching the
vicinity of poor Terrain data quality, followed by the suspension of all Terrain
alerts (the system may not be able to issue legitimate TAWS/Terrain alerts).
•ESP – May become disabled.
•SVT – May depict the aircraft as flying “through” terrain on the display.
The Terrain Data Alert is accessible via the NavData Alerts link at www.garmin.com.
PILOT ACTION
Pilots should utilize extra caution and awareness of the surrounding terrain when flying
within 30nm of the affected airports listed in the referenced Terrain Data Alert. Pilots
may consider inhibiting TAWS/Terrain alerts when flying approaches into the affected
airports.
RESOLUTION
Future Terrain Database upgrades will be made available to correct this issue.

Garmin requests that the flight crew report any observed discrepancies related to database information.
These discrepancies could come in the form of an incorrect procedure, incorrectly identified terrain,
obstacles, fixes, or any other displayed item used for navigation or communication in the air or on the
ground. Go to FlyGarmin.com and select “Aviation Data Error Report.”
