Section 3
Traffic Avoidance
TIS LIMITATIONS
Traffic may not be displayed for one or more of the following reasons:
1. Radar site is out of service. If a TIS capable Mode S sensor is not in
service for any reason, TIS is not available. See Figure 3-11.
2. Your aircraft is beyond maximum range of a TIS capable Mode S
site. Maximum range can extend beyond 55 NM up to 100 NM.
However, expect TIS service to 55 NM. See Figure 3-11 and 3-12.
3. Your aircraft is inside the “Cone of Silence. When near or above
(depending on altitude) the TIS radar site, and out of range of another
TIS radar site, TIS data cannot be received. See Figure 3-13.
