TCAS RAs
ATC Watcher - indeed, the TCAS aspect of the report (and, of the incident itself) struck me as quite significant, possibly worthy by itself of a thread. The mid-air tragedy over Uberlingen led to a product liability lawsuit under EU legal principles; according to one published report, the absence of reversal Resolution Advisories was a defect in the TCAS system and/or its software as it existed at that time. At least, in this incident, reversal RAs were generated by the system, according to the AAIB report.
Fortunately the Houston incident will not become one of the subjects of study in a law school course, unlike the tragic mid-air and its nearly unbelievable aftermath. Still, the CRM aspects appear highly instructive. Not least, in situations where there was no calamity and the aviators can provide input, perhaps more lessons can be drawn, as compared to determinations of cause and effect where only things like wreckage, data recorders, and laws of chemistry and physics can do the talking.
