6. Traffic Information Service (TIS)
a. Introduction.
The Traffic Information Service
(TIS) provides information to the cockpit via data
link, that is similar to VFR radar traffic advisories
normally received over voice radio. Among the first
FAA
−
provided data services, TIS is intended to
improve the safety and efficiency of “see and avoid”
flight through an automatic display that informs the
pilot of nearby traffic and potential conflict
situations. This traffic display is intended to assist the
pilot in visual acquisition of these aircraft. TIS
employs an enhanced capability of the terminal Mode
S radar system, which contains the surveillance data,
as well as the data link required to “uplink” this
information to suitably
−
equipped aircraft (known as
a TIS “client”). TIS provides estimated position,
altitude, altitude trend, and ground track information
for up to 8 intruder aircraft within 7 NM horizontally,
+3,500 and
−
3,000 feet vertically of the client aircraft
(see FIG 4
−
5
−
5, TIS Proximity Coverage Volume).
The range of a target reported at a distance greater
than 7 NM only indicates that this target will be a
threat within 34 seconds and does not display a
precise distance. TIS will alert the pilot to aircraft
(under surveillance of the Mode S radar) that are
estimated to be within 34 seconds of potential
collision, regardless of distance or altitude. TIS
surveillance data is derived from the same radar used
by ATC; this data is uplinked to the client aircraft on
each radar scan (nominally every 5 seconds).
b. Requirements.
1.
In order to use TIS, the client and any intruder
aircraft must be equipped with the appropriate
cockpit equipment and fly within the radar coverage
of a Mode S radar capable of providing TIS.
Typically, this will be within 55 NM of the sites
depicted in FIG 4
−
5
−
6, Terminal Mode S Radar Sites.
ATC communication is not a requirement to receive
TIS, although it may be required by the particular
airspace or flight operations in which TIS is being
used.
