edward, the big problem when you make a lift dumper in the flight simulator is the problem that your speedbrakes are attached to it.the speed brake from F100/70 are in the tail, not affecting the lift, just incriasing the drag.the lift dumpers deploy just after the touchdown, and destroy the lift.and is IMPOSSIBLE far as I know to work with two different surfaces as speedbrake and lift dumper.

Bob,I guess that you had noticed that the only problem in the mr. probst panel is that the main view have too many gauges and you may get confused.as Macs told, the best way if you take the project forward, is to switch some gauges to a pop-up window.(again) If you guys need an EPR formula for the -17 (the only chart that I have to make the formula) and a FDE to the /adv, contact me via e-mailomykronbr *at gmail dot comwould be great see a "joint venture" to take lead in works of the mr. probst panel.regardsGustavo

Great Emilio.But I must recomend to do more work in the rest of the panel, like the AP logic for the CWS (guess that I

Will be in the FSX a simulation of reverse clam-shell like in the MD80, Fokker-100 and B732 sistem?the actual is more like a small reverse percente of the real effect of'em, not really making the reverse effect of clam shell engines.

sim1.dll affects the ground friction, not the tire friction (where I presume is the problem).a normal drag coefficient in a runway, is about 0.5 (sorry, forget the scalar value), below .45, the runway has low friction and must be operated with caution, or you can skid in the runway.the real value over sim1.dll is unknow, and only the FS ACES team can give us a clue...

or even after all, a good SDK for flight dynamic (.air files), explanation of tables of the archives .air, as they intervene with the flight dynamics and as to adjust such values in order to improve the flight.

more effects on terrain when you don

Is a possibility that you can try.I

Did you ever consider that you're making standard turn in the right way.try to make a turn at 170kias, keeping this speed (increase pitch, increase thrust, small ruder to avoid aircraft glissing, keep the airspeed and the bank and altitude).if I

There is possible change the cargo load image for another aircraft, with larger size, or even with the same size from the original cessana image?Regards

Hi. I

I ready the posts from Ron (they all helped me.) but I was with doubt in one pointthe .AIR table 1032 has a EPR calibrate, and the EPR rate of change.so, has a variablethe token variable is TURB_ENGINE_1_EPRthis variable is accurate?
