FDE PREDICTION PROGRAM
Your 400/500 Series Trainer software includes an FDE Prediction Program to meet the requirements for GPS as a primary means of navigation for oceanic/remote operations (reference FAA Notice 8110.60). The oceanic flight phase occurs on your 400/500 Series unit when you are more than 200 nautical miles from the nearest airport. All operators using the 400/500 Series unit as primary means of navigation in oceanic/remote areas under FAR parts 91, 121, 125 and 135 must utilize the FDE Prediction Program prior to conducting a flight in these areas.
All operators must also utilize the FDE Prediction Program prior to navigation on U.S. RNAV routes, SIDs, and STARs if a NOTAM indicates a GPS satellite (or satellites) is scheduled to be
FDE is an acronym for Fault Detection and Exclusion. The detection function refers to the capability to detect a satellite failure which can affect navigation. The exclusion function refers to the capability to exclude one or more failed satellites and prevent them from affecting navigation. The FDE function is built into the 400/500 Series unit and does not require pilot interaction. In contrast, the FDE Prediction Program does require pilot interaction and must be used prior to oceanic/remote area flights, and for U.S. RNAV routes, SIDs, and STARs to predict FDE availability. The FDE Prediction Program allows you to specify the planned ground speed, route space, and maximum allowable outage. When provided through NOTAM or other sources, satellites with known failures can be excluded through the program's setup function.
To use the FDE Prediction Program, begin by entering the intended flight plan into the 400/500 Series Trainer software. The FDE Prediction Program uses this information to analyze satellite coverage along your intended route of flight.
To create a flight plan prior to using the FDE Prediction Program:
1.With the 400/500 Series Trainer running and the simulated 400/500 Series unit on, click on the unit’s FPL button to display the flight plan pages.
2.Click on the clockwise arrow of the unit's small right knob to display the list of saved flight plans.
3.Click on the unit's MENU button, then click on the clockwise arrow of the unit's large right knob to highlight "Create New Flight Plan?". Click on the unit's ENT button to begin creating a new flight plan.
4.Use the unit's small and large right knobs to enter the identifier of the first flight plan waypoint. Click on the unit's ENT button once the identifier for the desired waypoint is displayed.
5.Repeat step #4 to enter each additional flight plan waypoint, ending at the final destination airport.
Prior to running the FDE Prediction Program, the flight plan created in the preceding steps needs to be activated. The FDE Prediction Program only works with the currently active flight plan.
To activate a saved flight plan:
1.With the 400/500 Series Trainer running and the simulated 400/500 Series unit on, click on the unit’s FPL button to display the flight plan pages.
2.Click on the clockwise arrow of the unit's small right knob to display the list of saved flight plans.
3.Click on the unit's small right knob to enable the cursor, then click on the clockwise arrow of the large right knob to highlight the desired saved route.
4.Click on the unit's MENU button, then click on the clockwise arrow of the unit's large right knob to highlight "Activate Flight Plan?". Click on the unit's ENT button to activate the flight plan. The active flight plan page will be displayed (Figure 2).
