Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:
- Tag FS2020 specific questions with the MSFS2020 tag.
- Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
- Questions about aircraft design can be posted in the Aircraft design forum
- Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
- Questions about terrain design can be posted in the FS2020 terrain design forum.
- Questions about SimConnect can be posted in the SimConnect forum.
Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.
By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.
Making stallspeed go up!!

If the clean stall speed (flaps up) is correct and you want to increase the dirty stall speed (flaps down) only, you have simply to reduce the flap lift factor.
You can do this:
- in the air file (section 1101 or 1539 if present) modifiying the CL_df (coefficient of lift delta flaps)
- or changing lift_scalar in the AIRCRAFT.CFG.

Okay, you have first to set the correct stall speed for the clean configuration (flaps and gear up). Actually you have to set not a speed but the Angle of Attac for maximun lift. Usually normal aircraft (no delta, no short wings and such unusual configuration) will stall at about 14° til 17° AofA.
You can do this with modifications of the air. file, you have simply to change the shape of the top of the curve in section 404 (Cl vs AofA). If you reduce the coefficient of lift for a given Angle of Attac, the stall speed will increase.
If your air file has a section 1545 you have to make this editing in this section since she overwrites section 404. But the use of section 1545 is not raccomandable due of some errors.
I think it is easyer if you do this editing with AAM.
Beware: In the aircraft.cfg there is the line "flaps_up_stall_speed". This line is/was used by Microsoft FS Editor an has no meaning for the simulation itself. Changes to this line don't have any effect on the actual stall speed.
After the stall speed clean you can adjust the stall speed dirty.
Hope it helps
