BendixKing CAS 67A TCAS II - Manual (Page 16)

THE TA/VSI INSTRUMENT
The TA/VSI combines the plan position of intruding aircraft and TCAS
II guidance on the vertical speed instrument.
A pointer and circular vertical speed scale indicate aircraft vertical
rate. Climb and descend Resolution Advisories are shown as red and
green bands outside of the scale. The center of the display presents
intruding traffic. Refer to Section II for a detailed description of the
TA/VSI.
HOW TO FLY TYPICAL TCAS II COMMANDS
The Resolution Advisory is incorporated into the Vertical Speed
Indicator. By illuminating red and green light bands around the dial,
“Fly-To” and “Fly-Away-From” commands are displayed coinciding
with the required vertical rate. Maneuver the aircraft promptly and
smoothly in response to the Resolution Advisory.
Some of the typical Resolution Advisories shown on the RA/VSI will
require a maneuver by the crew while others will warn against
maneuvering. A typical TCAS II maneuver requires crew response
within 5 seconds and G-forces of ±.25G.
The following diagrams illustrate typical TCAS II encounters showing
intruder traffic on a display and the corresponding resolution on the
RA/VSI.
