Applicable to:
In case of RA detection, the vertical speed scale becomes rectangular and the PFD presents vertical
orders on the vertical speed scale. The vertical speed scale background is normally grey, but may be
partially replaced by green and/or red areas.
Note: When TCAS information has to be displayed on the vertical speed scale, the grey
background of the air speed and heading scales are removed.

(1) Red area
Indicates the vertical speed range, where the risk of conflict is high.
(2) Green area
Indicates the recommended vertical speed range. ("FLY TO" sector). It is wider than the red
area.
Note: The aircraft can also fly in the grey vertical speed range ‐ without the risk of conflict
(preventive RA).
‐ In case of RA detection, the vertical speed needle, that is normally green, becomes
white.
(3) TCAS message
It appears in red, when the TCAS cannot provide RA data, or in case of a TCAS internal failure.
