SFC and RRC

[Rob777]

Surface Friction Coefficient and Rolling Resistance Coefficient

I decided to start a thread on this to see if anyone had any inputs on better values. I put this into another thread and had no replys. The values below are what I am currently using. If anyone has thoughts for improvements, please post them.

My current values are:

SFC 1.4

RRC .40

That's about what I use for off runway SFC.

Isn't the RRC a bit low though?
