Hello X-Plane experts and pilots alike! I just finished building an Airspeed Indicator from scratch using just generics and Gimp. My new Airspeed Indicator is for my Commander 114/115TC home cockpit project. My AI has a true airspeed scale that needs to be adjusted, however I can't find a DataRef for the adjustment. The attachment is below. Can someone point me to a DataRef that can be used to turn/adjust the scale? Thanks in advance.
