1.3 System Capabilities
AT-1 detects other traffic transmitting FLARM, ADS-B or Mode-S transponder data. Moreover,
AT-1 broadcasts the own aircraft’s position, altitude, and trajectory to other aircraft using
FLARM.
AT-1 exchanges data with avionics systems in the own aircraft using a broad range of
standardized data interfaces. AT-1 is compatible to a wide range of cockpit systems including
traffic displays, navigation systems, apps on tablets or smartphones, audio systems, and
warning annunciators.
As there are neither minimum performance standards (MPS) nor technical standard orders
(TSO) for FLARM based collision warning systems, AT-1 is not certified. It can be legally
installed into many aircraft types based on several regulations covering installation of
non-TSO articles, for example by means of EASA Standard Change Approvals (CS-STAN) or
specific EASA Minor Change Approvals or Supplementary Type Certificates (STC) that have
been created by AIR Avionics or third-party organisations.
AT-1 cannot be used as a replacement for certified TAS/TCAS systems. It may not be used as a substitute
for these systems, especially, not in cases where the installation of TAS/TCAS systems is mandated.
