The VDI scale provides tick marks for zero deviation, half and full scale (up,
down). The navigation source is displayed to the below the VDI and will indicate
either ILS or FMS. A white VDI pointer indicates course deviation; if the pointer
exceeds full scale deviation, it turns amber.

Vertical Deviation Indicator- Full Scale
If the PFD detects vertical deviation data as invalid or failed due to lost
communications, without a change in VLOC frequency or a change in Primary
Navigation source, the VDI pointer is removed, the associated text turns red and
a red X that covers the VDI.
