I have about 70 hours in a B200 and 10 in a 1900C in real life... And on pretty much all turboprops for fs9-fsx that I have downloaded (just downloaded the PMDG 1900c for FS9) it seems the ITT and torque values are opposite of what they should be...What I'm saying is, at low altitutes you are torque limited, the engine will easily over-torque;the air is more dense, and at high altitudes you are ITT limited. These engines operate similiar to a constant speed piston with manifold pressure... You set the takeoff power, usually 3000 lbs of torque for the 1900c for each engine, and the ITT shouldn't max out... As you climb, the torque starts to drop off and you keep adding power until you reach max ITT, much like manifold pressure, you keep adding as you climb, unless in a turbocharged piston it should hold fairly constant until it's max alt.... 740 is what we operate for max ITT and cruise in the B200, not sure what we operate the 1900 at, as I'm still training, but probably around the same area. Basically what I am wondering is why none of the FSX turboprops emulate this, they are all the opposite... Such as the PMDG 1900c... You set take off torque at 3000lbs and the ITT is over redline, when it shouldn't be...(given it is possible under certain atmospheric conditions)... And as you climb torque increases (initially but eventually starts droping, but much to slow of a rate) and ITT decreases, not accurate... Are there any turboprops that accurately portray these values in real life?... or is there a way or a mod to fix this problem? And as you descend ITT will drop off, but torque will increase, so you always keep an eye on torque in descent to avoid over-torque the engines...this also isn't portrayed correctly.Also when you pull by props for climb settings, usually 1650rpm for the 1900c, torque doesn't increase, as it should... Most of the time you have to pull back torque about 100lbs before you pull back the props, because torque will increase as the props slow down and take a bigger bite of the air...Granted you probably wont over-torque since you take off with 3000lbs which is already a few hundred lbs below max torque, if you dont pull back power to adjust for this...I find it very frustrating when I spend money on payware aircraft that don't accurately portray systems (especially engines) that the real life aircraft have... I like to use FS as somewhat a training tool to keep myself fresh, as I don't get to fly in these planes very often in real life yet, but will be in the next year or so.

Howdy,Ya, it's commonly accepted the the FSX free-turbine model is pretty weak...and not really the most accurate.The 1900's by PMDG were older "Express" products, and weren't really developed beyond the FSX default aircraft variables and systems and such...they are basically just well made .air files with a decent exterior model and such. I don't have the PMDG 1900's....but I know when playing around with the default King Air and Aerosoft's Twin Otter I get T5's temp all over the place too.They won't really simulate the -65's (I'm pretty sure right?) you'll find on your 1900C really well.The J41 is a pretty good turboprop simulation, although it's fixed shaft (which FSX doesn't even know) and the J41 has a lot of clever funky computer stuff logic going on to try and get a reasonable sim.The best free-turbine sim I have experience with is the Majestic Software's Dash 8. The numbers are pretty much spot on with the real world PW 127's from my experience. SOP's frequently use a 730 degree temp to set cruise. We'll have to see how the PMDG Dash-8 works with the FSX limitation.Patrick H

Yeah it's pretty disapointing, hopefully Microsoft Flight might do a little better...that is if my computer can handle it..haha...It can barely handle fsx on medium-low...that's why I went back to fs9 which runs smooth at full...I found the Flight1 Aeromax B200 Xtreme has a more accurate engine modeling and very realistic flight characteristics, I would recomend checking that one out if you haven't...All of the other systems are very realistic too, you can literally control every aspect of every system, enviromental, electrical..etc... I'll check out the Dash 8, don't know too much about those but sounds like it's worth a shot!I do have JS41 from PMDG, and it's pretty awesome, if my computer could run it smoothly :(Thanks Patrick.

Ya i'd get the Aeroworx King Air....If I could get it to work on FSX :( Don't got FS9!You'll find the Majestic Dash very neat. It's not the best looking panel and stuff out there...but it's an awesome simulation...with finally an aircraft that models Beta and Alpha mode's correctly.Bit pricey though.
