RuNNINg ThE FDE PREDICTION PROgRAM
Trainer and route planning software for WAAS-certified Garmin products include a WFDE Prediction Program to meet
the FDE requirements for GPS as a primary means of navigation for Oceanic/Remote operations (reference FAA AC 20-138A
Appendix 1).
To use the WFDE Prediction Program, begin by entering the intended flight plan into the applicable Garmin Trainer
software or the Garmin Route Planning software. The WFDE Prediction Program uses this information to analyze satellite
coverage along the intended route of flight.
NOTE: A flight plan must be created and activated (using the applicable Trainer or Route Planning software) prior
to running the WFDE Prediction Program. The WFDE Prediction Program only works with the currently active flight
plan. Follow the software instructions to create and activate a flight plan. Software and instructions are available
via the Garmin website at www.garmin.com.
Running the WFDE Prediction Program:
1) Make sure the applicable Trainer or Route Planning software is running . If using a Trainer program, make sure
the simulated unit is on, and the desired flight plan is active.
2) If using a Trainer program, select the "Options" menu (Figure 5) in the upper left corner, and select "WFDE
Prediction Program" (G1000 Trainer and GTN Trainer), "Fde Prediction Program" (GNS 400W/500W Trainer),
OR
3) If using the Garmin Route Planning Software, click on the "Start Prediction" button after setting up the route
(Figure 5).
NOTE: If the WFDE Prediction Program has not been used previously, or has not been run recently, a series of
pop-up messages (Figure 6) may precede the WFDE Prediction Program window. Follow the on-screen instructions
to download new data from the internet. The download time is normally very short (nearly instantaneous), but
may vary with internet connection. See the "Updating/Changing the Almanac and Configuration Files" section of
this document for details.
