LATERAL/VERTICAL DEVIATION INDICATION

Magenta diamond for FMS deviation. Green trapezoid pointer used for LOC.
When both are displayed during PREV mode the FMS pointer overwrites the LOC pointer when both are at the same point. In PREV mode the trapezoid is displayed in cyan.
When a valid deviation is not available a X is depicted.

Pointer is controlled by the selected primary navigation source (PNS).
Vertical deviation scale is displayed when:
- Localizer (LOC) is selected as the PNS.
- FMS is selected as the PNS, and the FMS commands the VNAV vertical scale in view.
ILS LOC deviation pointer is a green trapezoid. VNAV FMS is a magenta hollow diamond.
When glideslope data is invalid or when the vertical deviation scale is commanded into view by the FMS and a valid deviation is not available a X is depicted.
Preview vertical deviation is displayed when LOC is the PREV source.
LOC and FMS deviation are displayed the same way as the lateral deviation.
