4 INTERPRETING THE FDE PREDICTION RESUL TS The GPS/FDE A vailability Results screen provides either a “GO” or “STOP” status for the GPS, RAIM, FDE, LNA V RAIM, and LNA V/VNA V & LPV minima availability . A yellow flag is a possible result for an FDE prediction for a non-Oceanic prediction (see Figure 12).
Suggestions to change the result of a failed flight plan prediction: 1) Alter the departure date and time . 2) Alter the route of flight. 3) V erify any deselected satellites . It is possible that some satellites unav ailable for a previous prediction are now available .
5 UPD A TING/CHANGING ALMANA C AND CONFIGURA TION FILES 5.1 ALMANAC, GEO ALMANA C, AND CONFIGURA TION FILES T o ensure that each is current, the Almanac, GEO Almanac, and Configuration Files are automatically checked each time the program is started.
5.2 CHANGING THE CONFIGURA TION FILE The WFDE Prediction Program may be used with several different Garmin software programs. Each program uses a specific configuration file to run the WFDE Prediction Program.
6 PRINTING 6.1 PRINTING THE PREDICTION RESUL TS Use of the “Print” selection on the “File” menu (in the upper left-hand cor ner) is not recommended, as the complete results of the prediction are not included on the printout. If a printout is desir ed, use the following steps.
