Integration Notes:
1. Peaks Elevations are transmitted digitally to the display via Label 025 on the ARINC 453 bus. They are then displayed as stroked
characters on the bottom left or right of the display (depending on EFIS strapping).
2. To Pop Up the Terrain display for a Terrain Caution or Warning it is necessary for the EFIS to receive two discrete signals from the
EGPWS (one to indicate that the Terrain display 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.
3. 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.
4. Software Level 14 required for integrated display and popup.
