Mode-S Datalink?
Does anybody know what kind of datalink-capability is available in current mode-s transponders? As far as i know two tcas-equipped aircraft can do coordinated RAs, so there must be some kind of a datalink. Unfortunately i don't get more information out of the manuals for the airplane i fly (B733).. .Mode-S should be capable of a lot of information to be transmitted, but do current transponders use that?
