TCAS II Resolution Advisory Display
-- The TCAS II system
displays a green “fly to target”band and a red “do--not--fly”band on
the vertical speed display that commands the pilot to comply with a
resolution advisory (RA) to avoid a potential aircraft conflict.
D
Vertical Speed Digital Display
-- A green digital display of the
actual VS value is located on the zero reference line. This data is a
magnification of the digits on the scale and is readable to a 50 feet
per minute resolution. The maximum value is 9900 feet per minute.
For values between
±
500 feet per minute, the digital display is
removed. At values beyond
±
500 feet per minute, the digital value
of vertical speed is displayed.
For vertical speeds greater than
±
3500 feet per minute, the pointer
is positioned in the appropriate direction near the end of the scale.
The digital display shows the actual vertical speed value.

Vertical Speed Analog Scale
-- The VS scale is a fixed scale with
a moving pointer. The scale on the display ranges from +3500 to
--3500 feet per minute. Display scale markings are 0, 1, 2 and 3. The
scale and its markings are white. The scale is expanded between
the +1000 to --1000 feet per minute range.
D
TCAS Status Message
-- The TCAS status messages are
displayed to the top left of the vertical speed display. When a TCAS
II RA is displayed, the vertical speed digital display matches the
color of the red or green band where the pointer is located.
