September 24, 200421 yr I have 3 simple questions about the PMDG B1900 in FS9: 1) On initial takeoff, gear up, flaps up- when prop RPM is reduced to climb, does the torque increase? 2) On the ground, engines at idle, props full forward, OAT 95 deg F (35*C), ITT at the lower part of red- if you bring the power levers up a little and increase engine rpm, does ITT drop? 3) On initial approach you lower approach flaps- does the nose definitely try to come up? thanks, lr.
September 26, 200421 yr Lou, I still have B1900D Manuals/Data from my Mesa days, I'll see if I can't answer your questions this evening when I get home. Mike CollierDispatcher/SOCAmerica West Airlines
September 28, 200421 yr Mike, I know the answers- my questions are regard the PMDG program modeling of the aircraft. It does seem rather strange that nobody, including the people at PMDG want to, or can, answer the question. lr.
September 29, 200421 yr Commercial Member Ross,Sorry for delayed response, as the original date of posting (25th Aug) coincided with holidays and then it got buried by a ton of messages.(1) Yes. That's why the proper procedure is **first** reduce TQ a little bit **then** reduce prop speed (same for piston engines where manifold pressure == torque)(2) MSFS (3) The B1900D is a aft CG aircraft (28-32% MAC). In other words an increase of main wing generated lift will result in a positive moment (pitch-up).Best,Vangelis===================================== E. M.

September 30, 200421 yr Okay thanks, Vangelis, I didn't know about the MS limitation concerning (2), but did want to compare the modeling to the real a/c. Thanks for your response. lr.
