For the TBM930 (only) others not tested
this works for me
1.13.16.0 - how to fly again - Community / General Discussion - Microsoft Flight Simulator Forums
Look for the line:
in the flight_model.cfg
[AERODYNAMICS]
lift_coef_ground_effect_mach_table
now is:
lift_coef_ground_effect_mach_table = 0.0565: 1.25
change to:
lift_coef_ground_effect_mach_table = 0.0: 1.10, 1.0: 1.10
now is:
lift_coef_flaps = 1.03210
change to:
lift_coef_flaps = 0.60000
test it
best regards
