A fan reported that my earlier Post 123 regarding Disable Unintended Auto-Pilot Wing Leveler doesn’t work on FSX’s default Airbus A321 and requested help for a fix.
The issue is caused by the activation of Fly-by-Wire (FBW) function on the aircraft and followings are two solutions:
FIX 1:
Open aircraft.cfg of A321 and modify the parameter of fly_by_wire from 1 to 0 under the [airplane_geometry] section
fly_by_wire=0
This will disable the fly-by-wire function simulated on the aircraft and allows the Auto-Pilot Wing Leveler (Ctrl-V) to work.
FIX 2:
