[5]3, 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.

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 [6]FIG 4

[7]-

[8]5

[9]-

[10]4, 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.
