I went to my local airport yesterday and much to my surprice there

I went to my local airport yesterday and much to my surprice there
was a squadron PC-7's stationed there. Careful listening reveiled
that there is a turbine sound (coupled to N2) and the propeller sound
which is so common for a turboprop engine cannot be heard when taxiing
around. This basically means the sound is propeller power related, but
since JSBSim doesn't model that I used the nozzle position (...) instead.

It really was great fun to be there yesterday with 6 PC-7's, and A320,
a Cessna Citation, somthing that looked like a turbine driven C172(!),
a pa-28 several F-16's and as a closing act the arrival of a Fokker-100!

'Nough said, back to action.
