Integration Notes:

•The EGPWS ARINC 429 Output Bus must be connected to the display.

•This display uses the following ARINC 429 labels from the EGPWS for annunciation: 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)

Note - Per customer request for EDZ705 and EDZ756, the display does not go blank when Terrain is Inhibited, nor is an amber TERR presented. This change is part of the EFIS system

•EGPWS ARINC labels are valid, but range in label 050 disagrees with range via SCI bus label 80 (Label 050 bits 11-14 contain the left display range and bits 15-18 contain the right).

The display will be blanked when the amber “TERR” is present.

The Terrain display will Pop Up to Terrain mode as follows:

•If all the conditions indicated by for the amber “TERR” above are FALSE.
