LeadSled,
FYI the data set used for programming the SIM comes from a current model King Air that is fitted with a very large number of sensors and a data gathering suit that would dwarf the average PC. It is then flown through a number of pre programmed flights by a test pilot during which all the data is recorded. Somehow, in a process beyond my knowledge, that is then transferred into the simulator software package. Australian, read CASA, input is limited to observing that the simulator flys and replicates the actual aircraft during all the various flight regimes. Hope that helps.
