Some aircraft in my FSx installation have a peculiar problem: When in the cruise, and generally above the critical altitude, full throttle height for turbocharged engines, I am unable to reduce the prop RPM down to anything like cruising RPM's. For example, an Me-109K is supposed to cruise at 1.0Ata (Roughly 30in HG) and 2100 RPM. From above 22,000 feet, to 25,000 feet, 1.0 Ata (Reducing from that above those altitudes) can only be had with full throttle. When I go to reduce my RPM's down to the cruise level of 2100 RPM, (Having disconnected all hardware so there could be no interference), using Cntrl F2, I find that I can only reduce the RPM's down to roughly 2500 - from 2700 in the climb. And I don't think it's because I'm going too fast, because in this case it normally occurs as I level out of the climb, and so my airspeed only rises slowly above the climb speed - it can't generally gain speed quickly because I can't lower my RPM to cruising levels..! What generally happens is that you pull the prop lever back to about 70%, which makes the change to 2500RPM, but then you can't reduce it any more, no matter how much you move the prop lever. This is a problem I have with several aircraft in FSx..
Is there some figure I can play around in the aircraft.cfg file that changes the behavior of the propeller RPM in the cruise - ie, allowing it achieve lower RPMs? Or does this require air file editing?
Later addition: Though this aircraft has nothing to do the one above, this is the same issue I'm experiencing, put more succinctly: http://forum.avsim.net/topic/350788-rpm-limit/
