ABBREVIATIONS AND DEFINITIONS (CONT’D)
Reversal Maneuver A reversal maneuver is a change of the
original Resolution Advisory command from
a climb to a descent or vice versa. The
reversal maneuver could require G-forces to
reach approximately ±.35 within 2.5 sec-
onds.
Self Test A functional test that determines equipment
status. Self test differs from BITE perfor-
mance monitoring because it is initiated by
the crew and is not performed continually or
automatically.
Surveillance Volume The volume of airspace surrounding your
aircraft that TCAS scans for intruding traffic.
The TCAS system scans approximately 40
NM in front of and 9000 feet above and
below the aircraft. The volume will automati-
cally begin to decrease when flying into a
high density area and may be reduced to
approximately 15 NM in front of the aircraft.
TA Traffic Advisory. An audio and visual indica-
tion that another aircraft is a potential threat.
A TA may become a Resolution Advisory
within 15 seconds.
TA/VSI Traffic Advisory/Vertical Speed Indicator. A
flight instrument that gives standard VSI
indication, plan position of local traffic, plus
RA climb and descend requirements.
Threat An aircraft that has satisfied TCAS threat
detection logic and thus requiring a
Resolution Advisory.
