Comparing fdm data against the actual aircraft, also provides early warnings of failures. ..FDM data can also help provide accident data, and using radiolinks or some such, communication of these between aircraft can prevent accidents. ..in traffic, this can help _route_ traffic and advice pilot of traffic conflicts, possibly advicing of an evasion route or manouver. ..midairs and near misses happen for one reason, mens failure. > Given that scenario, the remaining GIS and GUI components are only > providing a way to interpret the data feed and, in themselves, cannot > affect the acft.

Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
