Traffic Types
TIS-A
NOTE
Garmin is not responsible for Mode S geographical coverage. Operation of the ground
stations is the responsibility of the FAA. Refer to the AIM for a terminal Mode S radar site
map covering the U.S.
FEATURE REQUIREMENTS
•
Aircraft location is within the service volume of a Mode S terminal radar site
•
TIS-capable Mode S transponder is interfaced to the GTN
FEATURE LIMITATIONS
•
Except for GDL 88 or GTX 345 equipped aircraft, TIS and TAS may not both be
displayed at the same time
TIS is available only when the aircraft is within the service volume of a TIS-capable
terminal radar site. Aircraft without an operating transponder are invisible to both
Traffic Advisory System (TAS) and TIS. Aircraft without altitude reporting capability
are shown without altitude separation data or climb/descent indication.
TIS will be unavailable at low altitudes in many areas of the U.S., particularly in
mountainous regions. Also, when flying near the “floor” of radar coverage in a
particular area, intruders below the client aircraft may not be detected by TIS.
For information about TIS-A functions and limitations, consult the Aeronautical
Information Manual (AIM).
