Section 1.3 provides specific guidance for GTN 6XX/7X[...]

1.2 DETERMINING WHEN A WFDE PREDICTION IS REQUIRED The WFDE Prediction Pr ogram determines whether the GPS constellation is r obust enough to provide a navigation solution for the specified route of flight. As requir ed (dependent upon type of flight plan, GPS Software (SW) version, and GPS antenna), prior to departure the operator must use the [...]

* Approved refers to antennas listed in the applicable Installation Manual (T able 2) that allow the Garmin W AAS enabled unit with GPS software v3.XX or later to meet the TSO-C145a/C146a or TSO-C145c/C146c requirements without r equiring the operational limitations specified in the applicable Installation Manual. Unapproved refers to antennas lis[...]

2 IDENTIFYING GPS SOFTW ARE VERSION The GPS software version used in the Garmin W AAS enabled unit must be determined prior to performing the WFDE prediction. The GPS SW version may be a factor in determining if a WFDE prediction is r equired. 2.1 GNS 400W/500W SERIES PRODUCTS Identifying GPS Software V ersion of a GNS 400W/500W Series product: 1) [...]

A yellow flag is a possible result for an FDE prediction for a non-Oceanic prediction (see Figure 12). A “GO” status indicates th[...]

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 . 4) Update the almanac, especially if it is more than three months old. 5) Us[...]
