Integration note:

•Peaks Elevations are transmitted digitally to the display via Label 025 on the ARINC453 bus; they are then display as stroked charters on the bottom left or right of the display (depending on EFIS strapping).

•To Pop Up for a Terrain Caution or Warning it is necessary for the EFIS to receive two discrete signals from the EGPWS (one to indicate that Terrain is selected and one to indicate that selection was due to an alert). The EFIS needs to distinguish between manual selection and alert conditions so it will know when it should autorange. Both EFIS and EGPWS start to autorange on a Caution or Warning to minimize any latency problem displaying status during an alert.
