flight-planned destination.
It is displayed :
‐ During flight phases 7 and 8, and
If ‐ the QNH reference mode is selected.
(3) Ground reference
A red ribbon on the right of the altitude scale represents the field elevation. This ribbon,
which is driven by the radio altimeter signal, is displayed below 570 ft.
It moves up, as does the lower line of the attitude sphere, with the altitude scale as the
aircraft descends. When the aircraft has touched down, the top of this ribbon is at the middle
of the altitude window.
VERTICAL SPEED
Applicable to:
The displayed vertical speed information is normally based on both inertial and barometric data. If
inertial data is not available, it is automatically replaced by barometric information. In this case, the
window around the numerical value becomes amber.

(1) Analog pointer
This pointer, which is normally green, points to a white vertical speed scale displayed on a grey
background and graduated at intervals of 500 ft/min.
If the V/S is greater than 6 000 ft/min, the pointer stays at the end of the scale.
(2) Digital indication
This number, normally green, is the vertical speed in hundreds of feet per minute.
It disappears if the vertical speed is less than 200 ft/min.
The analog pointer and the digital indication become amber, if :
• V/S is greater than 6 000 ft/min, (climb or descent)
• V/S is greater than 2 000 ft/min, during descent when 1 000 ft < RA < 2 500 ft, or
• V/S is greater than 1 200 ft/min, during descent and RA < 1 000 ft.
Note: For TCAS Refer to DSC-34-80-20 PFD INDICATIONS.

HEADING
Applicable to:
(1) Heading Reference Line and Scale
A white scale on a grey background moves in front of a fixed yellow reference line to show the
actual magnetic heading.
(2) Selected Heading or Track Index (blue)
The pointer indicates the heading or track selected on the FCU HDG-TRK counter.
The index is replaced by digits on the right or on the left side of the scale, when the selected
value is off the scale.
If the FD pushbutton switch is OFF, a second heading or track symbol appears on the horizon
line and markers are displayed every 10 °.
(3) Actual Track Symbol
This symbol is a small green diamond.
(4) True heading (blue)
At high latitude above 82.5 ° North or 60.5 ° South (or entering the north, magnetic polar
region latitude 73.5 ° N and longitude between 117.5 ° W and 92.5 ° W), the ADIRUs replace
magnetic heading by true heading on the EFIS and DDRMI.
When the aircraft is in close proximity to these regions (latitude above 82 ° North or 60 ° South
or approaching the north polar region : 73 ° N and longitude between 90 ° W and 120 ° W), the
ADIRU causes the "SELECT TRUE REF" message to appear on the ND, thereby requesting a
change in the north reference.
