During an RA, vertical guidance indications appear on the Attitude Indicator and 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 6-125).

The Attitude Indicator will depict a range of pitch attitudes to avoid using no-fly pitch cues positioned on

the pitch ladder. The no-fly pitch cues are indicated by red open trapezoid-shaped areas encompassing the
range of pitch attitudes to be avoided during an RA. If an RA requires a change in existing pitch attitude, a
green rectangular fly-to pitch cue will appear above or below the no-fly pitch cue to indicate a recommended
pitch attitude. If multiple intruding aircraft limit available pitch travel in both directions, two no-fly pitch
cues will appear on the pitch ladder, indicating flight should occur between the two no-fly pitch cues.

While an RA is occurring, the Vertical Speed Indicator (VSI) will show vertical speeds required to resolve

the traffic conflict. 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
also turns 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.

Pitch cues on the Attitude Indicator and vertical bars on the Vertical Speed Indicator are removed when the

RA condition has been resolved. The TCAS II system will also issue an aural annunciation when the aircraft
is clear of the RA conflict.
