• 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.

MSFS Turboprop Power 'Hump' ?

Hello all,

Quick question. I have a turboprop engine model that is doing what I want, except.... that it has a 'hump' in the power range where it is calm and building, and then jumps up a very large amount. This is near the 50% range on the throttle. Adjusting your speed at that range is very difficult. Is there a way to spread out that 'hump' so that the spike is not so moderate?

This is in MSFS using an older version KingAir turboprop engine model.

If I add more 'coordinates' to the n1_to_shaft_torque_table= my engine quits, malfunctions, falls over.

n1_to_shaft_torque_table=0.000000:0.000000, 66.000000:0.097874, 100.000000:1.000000, 110.000000:1.100000

Any idea's?

Many thanks.

Its quite a mystery... In the throttle range, at about 145 knots, if I just 'think' about edging the throttle forward a bit, it jumps up to 155 to 160 knots. Its a odd 'jump' point. I cannot figure a way to smooth it. Its like the power arc goes from 10 deg to 50 degrees upwards.

It works so nicely when on the ground, taking off, etc. But adjusting throttle in flight in the slower speed ranges, you keep hitting this crazy hump in the RPM/power.

I found the issue. n1_to_shaft_torque_tableOn mine, to keep it tame on the ground, I had its angle extremely low, then high past halfway point. I found I could add 'one' more point into the table, and that helped quite a bit.

Glad I found this.

Hi,

I cannot answer to yours questions but you made me discover this new version of AAM that I did not know.
For that, thanks William for this pearl !
