What setting in the aircraf.cfg causes the plane to respond uncharacteristically when spoilers are deployed??? I'm currently working on an FDE and can't figure out what adjustments to make that would stop the plane from pitching nose down when spoilers are deployed and then snapping back (sometimes resulting in a high AOA) when they are retracted. I've noticed this and/or the opposite effect in other planes I've downloaded in the past but I have not been able to figure out what's causing this... Thanks for any advice you guys can give me...

Hello :)Look at the attached picture. http://forums.avsim.net/user_files/80032.jpgThe spoiler pitch effect can be adjusted within the aircraft's air file (*.air). You will need an air file editor such as http://members.dsl-only.net/~eagle/ :)Open the file, and find the appropriate value ... edit the value and save the file :)Try positive and negative numbers.I hope this helps!(Remember that you have to exit the air file in order to see the changes :) )

In the real world speed brakes (wing mounted) may produce a pitching moment depending on their position relative to the Centre of gravity. On the B707 the inbd speed brakes cause a nose down moment and the outbd speed brakes a nose up moment. The trailing edge flaps also have this effect and a fair degree of longitudinal control could be achieved by splitting the inbd and outbd controls. These pitching moments were all because of the swept wing. What this has to with MSFS I haven't a clue but maybe they model this somehow?Roger

You can also do this if you don't want to fiddle with the .air file:In the aircraft.cfg file, look under "Airplane_Geometry" for an entry called "Spoiler_Limit". That is the max number of degrees the spoiler will deploy. In the default 737, I think it is 40 degrees, and the nose dumps over like you said. I changed it to 15 degrees and now the airspeed washes off without the deep nose over.Hope that helps....

Thanks so much guys for your help on this... :-wave
