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 fl ight 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 fl ight 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 out-of-service (reference FAA AC 90-100).

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 fl ights, 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 fl ight plan into the 400/500 Series Trainer software. The 

FDE Prediction Program uses this information to analyze satellite coverage along your intended route of fl ight.

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 fl ight 

plan pages.

2.  Click on the clockwise arrow of the unit's small right knob to display the list of saved fl ight 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 fl ight plan.

4.  Use the unit's small and large right knobs to enter the identifi er of the fi rst fl ight plan waypoint. Click on the unit's ENT button once 

the identifi er for the desired waypoint is displayed.

5.  Repeat step #4 to enter each additional fl ight plan waypoint, ending at the fi nal destination airport.

Prior to running the FDE Prediction Program, the fl ight plan created in the preceding steps needs to be activated. The FDE 

Prediction Program only works with the currently active fl ight 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 fl ight plan pages.

2.  Click on the clockwise arrow of the unit's small right knob to 

display the list of saved fl ight 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 fl ight plan. 
The active fl ight plan page will be displayed (Figure 2).
