ChartView™ Database (GTN 725/750 Only)
ChartView resembles the paper version of Jeppesen terminal procedures charts. The charts are displayed
in full color with high-resolution. The GTN depiction shows the aircraft position on the moving map in
the plan view of approach charts and on airport diagrams. The ChartView database is stored on an SD
memory card that remains in the GTN for normal operation. The ChartView database is updated by
removing the database card from the GTN, updating the database on the card and reinserting the card.
Each card can only be used with one system. GTN users update their ChartView data by purchasing
database subscription updates from Jeppesen Sanderson. The database card is programmed using an SD
card reader and Jeppesen-provided software. Contact Jeppesen at 800-621-5377 or
www.jeppesen.com
for more information and instructions.

SafeTaxi
®
Database
SafeTaxi diagrams provide detailed taxiway, runway, and ramp information at more than 900 airports in
the United States. The SafeTaxi database is stored internally in the GTN for normal operation. The
SafeTaxi database is updated by removing the database card from the GTN, updating the database on the
card and reinserting the card. Each card can only be used with one system. GTN users update their
database card by purchasing database subscription updates from Garmin. The database card is
programmed using an SD card reader. Contact Garmin at 800-800-1020 or go to

Terrain Database
The Terrain database is used to provide basic terrain awareness functionality. The Terrain database is also
used to provide TAWS alerts to the pilot (with TAWS software only). The Terrain database is available
from Garmin for updating as needed. The terrain database is updated by removing the database card from
the GTN, updating the database on the card and reinserting the card in the vertical card slot on the left
side of the GTN. The Terrain database can be downloaded via the internet and the card can be
programmed using an SD card reader. Contact Garmin at 800-800-1020 or go to

database is also used with Terrain awareness and TAWS functionality. The Obstacle database is updated
by removing the database card from the GTN, updating the database on the card and reinserting the card.
The Obstacle database can be downloaded via the internet and the card programmed using an SD card
reader. Contact Garmin at 800-800-1020 or go to

Fault Detection and Exclusion (FDE)
The GTN, when installed as defined in this manual, complies with the requirements for GPS/SBAS
primary means of navigation in oceanic and remote airspace when used in conjunction with the provided
FDE prediction program.
The GTN includes internal Fault Detection and Exclusion (FDE) software which is active for all flight
phases including oceanic and remote operations, en route and terminal, and precision and non-precision
approaches. FDE does not require any pilot interaction. The FDE consists of two parts:
The fault detection function detects a satellite failure that can affect navigation; and
The exclusion function is the capability to exclude one or more failed satellites and prevent them
from affecting navigation.
The FDE Prediction program is used to predict FDE availability. This program must be used prior to all
oceanic or remote area flights for all operators using the GTN as a primary means of navigation under
FAR parts 91, 121, 125, and 135. The FDE program is part of the GTN Trainer, available for download
from the GTN product information page on Garmin‘s website,
