Is it possible to implement a modification of CL as a function of mach ?

Asobo decided to restrict to legacy the CL vs mach table telling the modern model takes into account that effect natively. This is a mistake and global result doesn’t match desired result, especially for airliners et jets. Compressibility effect increases dCL/dAOA and decreases CL max in the meantime. Since modern model draws in real time CL vs AoA, I would suggest the implementation of 2 new tables in flight model.cfg :

CL0_mach_table which would give CL @ aoa=0 as a function of mach

CLmax_alphamax_mach that would give for several mach (10 would be great) the CL max and AOA of CL max. Example:

Mach:Aoa max:CLmax


thanks !

Hello

The lift_coef_mach_table will soon enter service with the new FM, probably with SU10.

As for the possibility to adjust stall aoa based on a series of parameters (mach included), it's in our backlog

Regards,
Sylvain
