This red area indicates excessive speed range.
(2) Amber area :
This amber area indicates excessive speed range while keeping an appropriate margin to
the maximum structural speeds.
(3) GREEN area :
The green area indicates the safe speed range.
(4) Target speed (green) :
This symbol indicates the optimum target speed.
During approach, it indicates the target speed for the approach.
(5) Actual Speed Reference Line (Yellow) :
This fixed reference line, next to a yellow triangle, indicates the aircraft’s current speed.
(6) Amber area :
The amber area indicates too low speed while keeping an appropriate margin to the stall
speed.
(7) Red SLOW area :
The red SLOW area indicates the speeds that are lower than the stall speed.

GENERAL
Applicable to:
There are five different displays (five modes to display navigation information) :
‐ ROSE ILS
‐ ROSE VOR
‐ ROSE NAV
‐ ARC
‐ PLAN
The Navigation Display (ND) can provide a weather radar image in all modes, except PLAN.
Note: In case avionics ventilation is not sufficient (e.g. due to a blower and extract fan failure),
and the Navigation Display (ND) Unit temperature exceeds a defined threshold, the ND will
not display the weather radar image, in order to limit power consumption and prevent a DU
overheat. Any additional increase in temperature will lead to a complete cut off of the power
supply to this display unit.

(2) Aircraft heading
The fixed yellow lubber line points to the aircraft magnetic heading on the moving white
compass rose. Small white triangles are fixed at 45 ° intervals on the circumference of the
compass rose.
“TRU” appears at the top of the compass rose, when it is displaying true heading instead of
magnetic heading (latitude above 73 ° North or 60 ° South).
(3) Selected heading or track (blue)
This pointer shows the heading or track indicated on the FCU's HDG TRK counter.
(4) Actual aircraft track (green)
This symbol is a small green diamond.
(5) Ground speed and true air speed (green)
ADIRS furnishes these speeds.
(6) Wind direction and speed
ADIRS provides the wind direction and speed. The digital direction is with respect to true north,
and the analog direction (green arrow) is with respect to magnetic north. The green arrow only
