This pointer is in yellow, and indicates the bank angle. When the bank angle exceeds 45 °, all
the PFD symbols disappear, except those for attitude, speed, heading, altitude, and vertical
speed. The display returns to normal, when the bank angle decreases below 40 °.
(4) Pitch Scale (white)
This scale has markers every 10 ° between 80 ° nose up and 80 ° nose down (every 2.5 °
between 10 ° nose down and 30 ° nose up). When pitch angle exceeds 25 ° nose up or 13 °
nose down, all the PFD displays except attitude, speed, speed trend, heading, altitude, and

vertical speed disappear. Beyond 30 °, large red arrowheads indicate that the attitude has
become excessive and show the direction to move the nose in order to reduce it. The display
returns to normal when pitch angle becomes less than 22 ° nose up or 10 ° nose down.
(5) Flight Control Protection Symbols
The display shows these symbols in green :
On the roll scale at ± ‐ 67 ° to mark the bank angle limits
‐ On the pitch scale at 15 ° nose down or 30 ° nose up to mark the pitch limits.
An amber x replaces these symbols if the corresponding protection is lost.
(Refer to DSC-27-20-20 GENERAL)
(6) Sideslip Index (yellow)
This trapezoidal index moves beneath the roll index. On ground, it represents the lateral
acceleration of the aircraft. In flight, it shows sideslip (as computed by the FAC). One
centimeter of displacement indicates 0.2 g. The sideslip index is against its stop at 0.3 g.
In case of engine failure at takeoff or go around, the sideslip index changes from yellow to blue.
Note: The sideslip target is blue, if :
‐ CONF 1, 2, or 3 is selected, and
‐ Any ENG EPR > 1.25 or one Thrust Lever > MCT (≥ FLX if FLX or DERATED TO),
and
‐ The difference between the ENG EPR’s exceeds 0.25.
In this case, the sideslip index is called β target.
When this index is centered with the roll index, the sideslip equals the sideslip target for
optimum aircraft performance.

Applicable to:
(1) Fixed Aircraft Symbol
This symbol is in black, and outlined in yellow. The yellow outline dims, if the flight crew selects
TRK-FPA, unless the FMA is in the TOGA or FLX mode.
(2) Roll Scale
This scale is in white, and has markers at 0, 10, 20, 30, and 45 ° of bank.
(3) Roll Index (yellow)
This pointer is in yellow, and indicates the bank angle. When the bank angle exceeds 45 °, all
the PFD symbols disappear, except those for attitude, speed, heading, altitude, and vertical
speed. The display returns to normal, when the bank angle decreases below 40 °.
