Integration Notes:
1. The EGPWS ARINC 429 Output Bus must be connected to the display.
2. The ‘DISPLAY BUS’ fault will be present only if both MG inputs have failed.
3. The Honeywell EFIS SG & MG provide Terrain display relay control.
4. 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.
5. The display uses the following ARINC 429 labels from the EGPWS for annunciations. The Terrain display will
annunciate: “TERR” in green or cyan (depending on the program) when the Terrain is selected and valid.
“TERR” in amber if Terrain is selected and any of the following conditions are TRUE:
• The EGPWS ARINC 429 output bus is missing or labels 050 and 051 are absent or unreadable for 2 seconds.
• EGPWS ARINC label 051 bit 13 = 0 (“Terrain Display Valid” bit FALSE).
• EGPWS ARINC label 050 bit 17 = 1 (“Terrain Inhibit” bit TRUE).
• EGPWS ARINC labels are valid, but the range in label 050 disagrees with the range via SCI bus label 80 (label
050 bit 11-14 contain left display bus range and bits 15-18 are the right display bus range).
The display will be blanked when the amber “TERR” is present.
The display will Pop Up to Terrain mode as follows:
