Thumbnail and TIS
traffic Information Services (tIS)
There are two versions of TIS: TIS-A and TIS-B.
Both are described below.
In the TIS-A system, ground radar sensors col-
lect target information. The ground radar sensor then
determines the targets in the vicinity of your aircraft
and their bearing relative to your track. Up to eight
of the targets are transmitted by the ground radar
sensor the next time it communicates with your TIS-A
enabled transponder.
In the TIS-B system, the ground radar sensors col-
lect target information much the same as in the TIS-A
system. However, with TIS-B, all targets collected by
the ground radar sensor are broadcast to all aircraft
equipped with UAT data link radios and that are
within coverage of UAT ground broadcast stations.
Polar navigation
When operating the GMX 200 in polar areas
(above 72° north latitude or below 60° south latitude),
the external position source must be set to True North
navigation. Select True North navigation by setting
Magnetic Variation to zero in the position source.
