Two of the following bearings can be displayed simultaneously:
· VOR 1 or, ADF 1, or Pilot FMS and
· VOR 2 or, ADF 2, or copilot
FMS.
Bearings are referenced to magnetic north unless true north is selected and indicated on the HUD.
Vertical deviation Scale
The vertical deviation scale is located to the left of the altitude tape. The vertical deviation scale
and the altitude tape move together to the right edge of the display to accommodate the FPV when
necessary.
Glideslope Deviation
The pointer is displayed to the right of the vertical deviation scale. A limited pointer deviation is
shown with half the pointer in view at the appropriate position corresponding to ±2.5 dots.
The glideslope deviation is displayed when the primary navigation source is LOC, the glideslope
deviation is valid, and the airplane is not in Back Course.
The glideslope Deviation scale is not displayed in TO or GA mode or when the Radio Altitude is
less than 50 ft.

VNAV Vertical Deviation
The VNAV vertical deviation is displayed to the left of the vertical scale when the vertical captured
mode is VPTH. A limited pointer deviation is shown as a half pointer in view at a position
corresponding to ±2.5 dots. Also the VNAV vertical deviation is shown when a Vertical Track Alert
(VTA) is annunciated on the PFD’s with the associated double Cchord.
When the FMS approach sensitivity is set to normal, the ±2 dots scale corresponds to the vertical
scale factor provided in feet. When the vertical scale factor is not provided, the ±2 dots scale
corresponds to ±500 ft. When the FMS approach sensitivity is not set, the normal sensitivity is
used.
Lateral Deviation Excessive Indication
The lateral deviation excessive annunciation is indicated by the lateral deviation scale flashing.
CAT 2 ILS Deviation Margin
The CAT 2 ILS deviation margin consists of 2 vertical dashed lines (lateral deviation limits of
approximately 1/3 of a dot) and 2 horizontal dashed lines (vertical deviation limits of approximately
one dot). When both limits are displayed, the shape of the CAT 2 ILS margin is a square. It is
displayed in relation to the FPV. The CAT 2 ILS deviation is displayed when:
· CAT 2 mode is indicated, and
· The DH is set to a value lower than 200 ft, and
· The Radio Altitude is less than 300 ft but greater than DH.
When the LOC lateral deviation is not valid, the lateral deviation limits are removed and the vertical
deviation limits are laterally centered on the FPV.
When the glideslope deviation is not valid, the vertical deviation limits are removed and the lateral
deviation limits are vertically centered on the FPV.

Lateral Deviation Scale
The lateral deviation scale is a conventional CDI scale that rotates with the course pointer
according to the course selected/desired track.
LOC Lateral Deviation
The LOC lateral deviation scale is a conventional CDI scale. The LOC lateral deviation is
displayed when the primary navigation source is LOC and a valid LOC frequency is tuned. The
LOC CDI is not displayed in TO or GA modes.
FMS Lateral Deviation
The FMS lateral deviation is a conventional CDI scale. The lateral deviation scale varies with the
FMS approach sensitivity as follows:
· ±5 NM when the lateral scale factor is not valid
· ±2 NM when the FMS approach sensitivity is set.
The FMS lateral deviation is displayed when the primary navigation source is FMS. The FMS
lateral deviation is not displayed in TO or GA modes.

VOR Lateral Deviation
The VOR lateral deviation scale is a conventional CDI scale. The VOR CDI is displayed when the
primary navigation source is VOR. The VOR CDI is not displayed in TO or GA mode.
