In article <airliners.1996.2399@ohare.Chicago.COM>, email@example.com says... >With a MODE C Xpndr on the other aircraft only a Traffic Advisory (TA) >would be issued. To get a Resolution Advisory (RA) the other aircraft >would have to have a MODE S Xpndr. Not True. RAs are generated against both Mode C and Mode S targets. The biggest difference between the two as far as TCAS is concerned is that if both aircraft have TCAS, they both also have Mode S and therefore TCAS-to-TCAS coordination between the two aircraft will occur which provides complimentary manuevers to each aircraft. For example, while one gets a climb RA the other will get a descend RA.
