	ADSB Out Performance Requirements to Support ATC FAA-2007-29305 January 28, 2008 Re: Comments of Rockwell-Collins The FAA should develop a two-stage ADS-B mandate. The first stage is a forward-fit mandate of 2013 with somewhat relaxed performance requirements [i.e., NACp ≥ 7, NIC ≥ 6] from the final 2020 mandate requirements. Re-assess plan to decommission TIS-B. There is a need for ASA applications to gap-fill missing traffic that is known about by other means of surveillance.

Specifically, Boeing states that the first phase should be limited to ADS–B Out and the performance requirements should be reduced to those required for ADS–B Out. Once this is accomplished, the FAA can focus on the development of ADS–B In applications and their performance requirements. The second phase would include an ADS–B In mandate when the standards are complete. Boeing and the FAA discussed WAAS in relation to ADS–B. In response to a discussion, the FAA clarified that the NPRM does not specify WAAS; it specifies performance requirements. By: DOT Index
