@Boris @EPellissier (anyone?)
Wonder if anyone can help with this ?
see the image below … Showing -7 Degrees body to wing incidence
PLEASE Tell me that nobody with the slightest clue has read this ???
DEV SUPPORT FORUM ???
Hello @NightMercury358
It’s hard to be sure without having a look at your aircraft but this sort of things can happen during the normalization process as it will try to correct an incidence it considers incorrect.
For example, this can happen if your zero lift AOA is very high, due to a misconfigured lift / AOA table.

Zero Lift Aoa MAX is 1.4
lift_coef_aoa_table = -3.15:0.0,-0.80:-1.145,0.0:0.50,0.276805:1.4,3.15:0.0
and as already stated, the Incidence is set at 2 Degrees positive
Can you give us access to your package so we have a look?

It really is a MASSIVE Package ..
can you not investigate from the Flight_Model.cfg ?
I cant see how anything else would be relevant
Check if using your flight model on the Simple Aircraft SDK sample is enough to replicate the problem and you can just send the cfg if that’s the case.
checking Thanks

BN2 flight_model.cfg applied to sample MySimple aircraft
The Wide Incidence Offset is still apparent ..
PM Sent with our flight_model file
Incidentally I have discovered that the same anomaly applies to the SDK Aircraft also
including the DA62 and Basic my aircraft model …
Converted this to a bug report and I will have one of our flight model engineers have a look.

@FlyingRaccoon Much appreciated
@FlyingRaccoon
Happy to report that the issue appears to be fixed in 1.5.2.0 (May 21st)
Many thanks for speedy turnaround
Glad to hear it 
@FlyingRaccoon
Hmm Bad news .. Version 1.5.4.0
Sureley the wing/tail - Body incidence should Never change ??
Wing incidence is SET at 2.3 degrees and the HStab set at -2
why is thius confusing graph showing such crazy details ?
and why is the Wing chord almost Fuselage length ?
Hello @NightMercury358
This is with the exact same cfg you provided in the first place?
Regards,
Sylvain
I think stabilities and the ai.cfg have been tweaked but the General Dimensions and angles remain the same..
Whats confusing me mainly is the fact that the wing (in the diagram) appears to be Disconnected from the fuselage ? It should remain 2.3 degrees although yes I appreciate the AoA would change
PS.. the wing area is shown as 30.2 ?? where it is actually 325 Sqft
It’s reporting in square meters
AHH .. I guess that is for consistency then 
I so wish they gave us a laughing emoji response… 
It seems like a huge problem we’ve been dealing with since day one is mixed units used in programming (and in aviation in general).
Some additional fixes will be made on the debug.
There are some units inconsistencies indeed.
Regarding the incidence value changing, the debug label is misleading.
It should be named “root wing incidence” instead and it is impacted by the position of the flaps.

Sylvain
