The FAA can rebroadcast trafc information about aircraft equipped with
the following transponder types: Mode C, Mode S, Mode ES, and UAT.
Mode A transponders and primary radar targets detected by the FAA are
not included in rebroadcasted trafc reports.
Since not all aircraft are ADS-B Out equipped and not all trafc is
rebroadcast, the use of the receiver does not preclude pilots from having
to perform “see-and-avoid” procedures.
Stratus 1S and 2S are not active trafc interrogation systems nor are
they ADS-B Out devices.
NOTE: The receiver is not likely to receive weather or rebroadcast trafc
information on the ground because ADS-B information is broadcast
by ground towers. The altitude at which the receiver begins to receive
weather and rebroadcast trafc information will vary depending on the
distance to nearby towers and terrain and other obstacles that may be
between the receiver and a tower.
