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 4−5−4, 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 an

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 of 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 4−5−5, 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.
