Mixed auto coordination

On a stick with twist rudder, i find it not as precise as pedal rudder. So i like to make use of auto coordination. Yet in some cases i definitely need separate rudder control (strong crosswind). Therefore i added a binding to my rudder definition in the joystick xml, that allows me to have auto coordination when i do not twist the rudder, and separate rudder control as soon as i do use the rudder. Just sharing this for people who might find this useful too.

Code: Select all

    <binding>
    <command>nasal</command>
    <script>
        setprop("/controls/flight/auto-coordination", (getprop("/controls/flight/rudder") == 0));
    </script>
    </binding>


Credit for the idea should go to Tikibar. He had it built into the 747-8i at one time (not sure if it is still in there). All i did was transporting the idea to the joystick, so it becomes available for all planes.

Kind regards, Vincent

What does it do? I don't understand the point?

It turns auto-coordination on when the rudder is not being deflected by the stick and vice versa. This means he can use auto-coordination most of the time, but override it and control the rudder manually for takeoff and landing.

true fancyness.

Shouldnt this be a fgdata distributed piece of jewel?
then make auto-coordination default, unless otherwise specified with a --prop=/the/non/normal/method/of/coordination=off

Then whats is the point of auto-coord if you have a rudder axis?

Trying to use it like a yaw damper?

My AP is getting a yaw damper, eventually, once I sort rudder control, and I think the 777 he flies might have once already.

No, using full non-auto-coordination, whenever i start using rudder axis. When i do not use it, i have auto-coordination. The reason for wanting that i stated before: I find twist stick rudder too crude to make all my turns with.

So recapitulating: It is an automatic switch between auto-coordination and non-auto-coordination. Non-auto-coordination is activated when i start twisting the stick, else i have auto-coordination.

This makes no sense. Ailerons for turns, not rudder! ?????????????/

Autocoord is not a yaw damper. It does this

Aileron *0.5 = Autocoord rudder output

So ???

Pilots make coordinated turns with aileron and rudder. Autopilot is a bit shabby and acts on aileron only. This is sufficient for shallow turns at high alt.
