Vertical Speed Display
RAs may be categorized into preventative and corrective RAs. The system issues a preventative RA to
prevent vertical maneuvers. During an RA, vertical guidance indications appear on the Vertical Speed
indicators of the PFD to provide visual pitch cues for the flight crew to use to achieve (or maintain) vertical
separation from intruding traffic (Figure 15). The flight direction will NOT provide guidance necessary to
satisfy the RA command.
While an RA is occurring, a red vertical bar appears on the VSI scale to indicate the range of vertical
speeds to be avoided during the RA. If the current aircraft vertical speed is within this red range, the
pointer on the VSI appears red. When an RA directs the flight crew to fly to (or maintain) a vertical speed,
a green vertical bar will appear on the VSI scale at the recommended vertical speed range. The bars on
the Vertical Speed Indicator are removed when the RA condition has been resolved.
