Integration note:

•Either weather or a weather test pattern must be displayed before Terrain can be viewed. The white weather annunciation “WX” will still be present when terrain is displayed.

•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.
