Oh yes, after re-reading through the different FOM's and the
corresponding player-xxx files I was already suspecting such a
correlation.
I noticed that even RPR doesn't support angular acceleration -
appparently the folks at SISO don't consider it to be meaningful for
dead-reckoning in such a use case.
Thanks for sharing your insight with me,
Martin.
P.S.: If the CERTI folks feel uneasy about me polluting the list with
FlightGear-related stuff, please don't hesitate to complain.
