Wheel slippage question

[eeeewwqq]

Hi! I'm developing game and I wonder if something can be used for drawing tire tracks on landing.
For example when landing on huge speed with brakes enabled I think there will be some slippage.

At what props to take look to implement it?

A simple way would be to use gear/unit[1]/WOW , which is "weight on wheels", and has a value of zero while airborne and changes to 1.0 when that gear strut starts to compress. You could begin the wheel mark at that point and extend it some predefined length.

If you want to get fancy you could also use the property gear/unit[1]/wheel-speed-fps and compare it to the ground speed of the airplane in fps. If the WOW is true and the wheel speed differs from the airplane ground speed by some value, then draw the mark.

Gear unit 1 is usually the left main gear, and gear unit 2 is usually the right main gear, but this may not always be the case since the FDM author has freedom to number the gear any way he wants.

Thanks, exactly what I was looking for
