Integration Notes:
1. 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.
2. The ‘IOC BUS’ fault will be present only if both MG inputs have failed.
3. The Honeywell EFIS SG & MG provide Terrain display relay control.
4. The EGPWS ARINC 429 Output Bus must be connected to the display
5. This configuration will cause the GPWS INOP, TERRAIN INOP, and WINDSHEAR INOP lamps to turn on only at
the beginning of the EGPWS Self Test.
6. Display channels 1 and 2 are multiplexed on ARINC 453 bus 1.
7. This display uses the following ARINC 429 labels from the EGPWS for annunciations:
Label 050 If bits 11-14 left range output from the EGPWS does not match left MFD range (via label 171), then
display white “RANGE MISMATCH” on the left PFD and MFD.
