How does Offset 0x2EA8 (aileron deflection) behave for differential ailerons

[PhilippM]

Good evening,

I'm trying to figure out how to read the deflection of various control surfaces from FS.

For the ailerons, offset 2ea8 (Aileron deflection, in radians, as a double (FLOAT64). Right turn positive, left turn negative.) seems to be appropriate. However, most modern aircraft have differential ailerons, where the upward deflection is larger than the downward deflection. That means, left and right aileron have different deflection angles, not only in sign, but in magnitude.

How can I read the deflection for left and right ailerons separately?

Regards,

Right. The offset definitions derive from FS98 days where that probably wasn't simulated.

However, I can obtain the separate deflections in FS9 and in FSX. I'm not sure which version you are needing. It isn't a difficult job in either case, it just means finding another free 8 bytes for the double value. It just has not been requested before.

Note that, for FSX, the value at 0BB8 is derived fromthe Left aileron position only, whilst the 2EA8 value is what SimConnect calls the "average", so you could actually derive both values. In FS9 it won't work though as there 2EA8 currently provides the left deflection and I've no idea how 0BB8 is derived.

Let me know. It isn't a big job -- I can include it in the next incremental interim releases if needed.

I've added new offsets for these in versions 3.989k (for FS9) and 4.636 (for FSX and ESP). Please see the Updated Modules thread in the Download Links subforum.

Hi Pete,

this is awesome! Thank you so much.
