TRAFFIC DATA BY SOURCE

Traffic Information Service (TIS)
NOTE: TIS-A is available only when the aircraft is within the service volume of a TIS-
capable terminal radar site. TIS-B is available when the aircraft is within the service
volume of an ADS-B ground station. Aircraft without an operating transponder are
invisible to Traffic Advisory Systems (TAS), Traffic Alert and Collision Avoidance Systems
(TCAS) and TIS. Aircraft without altitude reporting capability are shown without
altitude separation data or climb descent indication.
NOTE: TIS-A is disabled if another traffic system is installed. TIS-B, a component of
ADS-B traffic, can be used in conjunction with TCAS and TAS.
Traffic Information Service (TIS) is designed to help in detection and avoidance of other
aircraft. TIS uses the Mode S transponder for the traffic datalink. TIS receives traffic
information from ground stations and is updated every 5 seconds. The system displays up
to eight traffic targets within a 7.5-nm radius, from 3000 feet below to 3500 feet above the
requesting aircraft. Traffic is displayed using the symbols shown in the table below.
A Traffic Advisory (TA) indicates the current track of the intruder could result in a collision.
When traffic meets the advisory criteria for the TA, a solid yellow circle symbol is generated. A
TA which is detected, but is outside the range of the map, is indicated on the outer ring of the
traffic map by a half TA symbol at the relative bearing of the intruder.
