Which *standard* would you be referring to? Real turbines are operated with
fuel flow in pounds_per_hour and EGTs are displayed in Centigrade.
Converting is easy, just a question of where to do it?

As I later noted, it was operator error at this end. Data types mismatch
(sending a double and expecting a float).

I'll try to get some good perfromance data and run some flight profiles and
send you the results.

 I've got the nav displays working for VOR/ADF and ILSs and a simple FMC
going. Need to clean up a few things, then I'll commit them to the OpenGC
repository and send the FG changes for the opengc interface to Curtis.
