147: Wing Leveler Fix for FBW Aircrafts

| Tom Tsui

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.

123: Disable Unintended Auto-Pilot Wing Leveler

| Tom Tsui

Some aircrafts in FSX, both default and add-on (such as T210), will turn on Wing Leveler automatically when Altitude Hold is activated, meaning that manual control of the aileron is also disabled.

To regain the control of it, one can press Ctrl-V on the keyboard to disable (or enable) the function.

Better still, one can modify the aircraft.cfg files of such aircrafts, and add the following command lines under the [autopilot] section, so that Wing Leveler function could be independent from Altitude Hold permanently.

[autopilot]
default_bank_mode=0
default_pitch_mode=0

Assigning “1” to both values will reactivate the associated Wing Leveler function with Altitude Holder under auto-pilot mode.
