Before revision: AIS-P as an alternative to ADS-B TailLight implemented as a free addition inside General Aviation ATCRBS transponders, such as the AT-155, utilizes the AIS-P protocol to achieve all intended ADS-B advertised collision avoidance benefits in the terminal and en route airspace, but yet also has properties which no other aircraft collision avoidance system alternative provides: TailLight does not interfere with any other avionics systems, TailLight produces the maximum system capacity (up to 335,000 aircraft within line-of-sight of each other), and TailLight provides total interoperability with the other collision avoidance systems.
