Hello guys i am trying to balance an aircraft with values from reall charts but i need some help with some entries in .air file.The entries i need some help are the "1204","1515" and the "1534" In the 1204 i need some help to estimate the "8=16,int32,<16h> Main Wing Center of Lift" entry, in the 1515 i need some help to estimate the"4=18,double,Root Cord (ft)" and the "5=20,double,Unknown" and into the 1534 the value "3=10,double,*CoL Offset from MAC (in)".Currntly i am working on an a320 project airbus aircraft and the new custom aircraft.cfg is this.[airplane_geometry]wing_area=1317.55000 //Real valuewing_span=111.25000 //Real valuewing_root_chord=14.07000 //Real valuewing_dihedral=3.30000wing_incidence=0.00000wing_twist=0.00000oswald_efficiency_factor=0.76500 //0.745 Pa valuewing_winglets_flag=1wing_sweep=25.00000wing_pos_apex_lon=15.57200 //16.813 Pa valuewing_pos_apex_vert=0.70000//htail_area=333.68000htail_span=41.67000htail_pos_lon=-57.34000htail_pos_vert=6.50000htail_incidence=0.00000htail_sweep=0.00000//vtail_area=231.42000vtail_span=17.99000vtail_sweep=0.00000vtail_pos_lon=-54.52000vtail_pos_vert=19.91000//elevator_area=76.50000aileron_area=57.00000rudder_area=56.20000//elevator_up_limit=25.00000elevator_down_limit=15.00000aileron_up_limit=25.00000aileron_down_limit=15.00000rudder_limit=25.00000elevator_trim_limit=13.50000spoiler_limit=50.00000//spoilerons_available=1 aileron_to_spoileron_gain=1.50000 min_ailerons_for_spoilerons=12.00000 min_flaps_for_spoilerons=0.00000 spoiler_extension_time=1.50000spoiler_handle_available=1auto_spoiler_available=1//positive_g_limit_flaps_up=5.00000negative_g_limit_flaps_up=-4.00000positive_g_limit_flaps_down=3.50000negative_g_limit_flaps_down=-3.00000load_safety_factor=1.00000I have found these values for the a320 from web search : Model A320 Wing: Area_(m?) = 122.40 Span_(m) = 33.91 MAC_(m) = 4.29 Aspect_Ratio = 9.39 Taper_Ratio = 0.240 1/4_Chord_Sweep = 25.00 High_Lift_Devices: Trailing_Edge_Flaps_Type = F1 Flap_Span/Wing_Span = 0.780 Leading_Edge_Flaps_Type = slats I would be really greatfull guys if anyone of you can help me to of how i can estimate the values of the .air files i have wrote above and if anyone of you has any of the missing real values of the a320 so i can write an aircraft.cfg for this aircraft to fly as much possible close as in reality.Many thanks in advance.

None of those are necessary.

say me lykon how was your change. how did a320 effect when landign after changes
