Integration Notes:
1. The EGPWS ARINC 429 Output Bus must be connected to the display.
2. When there is a Terrain Alert and the FDS 255/2000 is not currently displaying Terrain it will set its range to 10 NM
and Pop Up to Terrain mode. The range does not change if Terrain mode is already selected when there is a Terrain
Alert.
3. When interfacing to a single display controller configuration the bus must be connected to both EGPWS input
channels. This prevents the EGPWS from reporting an external bus fault on the second channel.
