WFDE Prediction program INSTRUCTIONS 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) Verify any deselected satellites. It is possible that some satellites unavailable for a previous prediction are now available. 4) Update the almanac, especially if it is more than three months old. 5) Use the correct antenna selection (if "Most Conservative" was used). 6) For Oceanic/Remote operations, determine the actual maximum allowed outage and use for the prediction (instead of the 5 minute default setting which is generally shorter than the actual allowed outage time). 190-00643-01 Rev.
