Hi Ron, I did find the bindings and nasal properties as you mentioned here, but thank you for the additional explanations. For the time being I'm going to look at some more normalized braking forces per aircraft based on the following criteria. - individual aircraft "average" landing weights per mfg specs. - mfg published runway landing distances, per std FAR's (3 degree glideslope over 50' obstacle) - FG user using keyboard braking
One thing I may ask about as well is the ability to write a rain condition into it, with reduced braking effect. Most mfg's publish landing distances for both wet and dry surfaces. What I don't know is if you can extrapolate "rain" from live metar or not. If I find that it can be accomplished with a little time per aircraft than I may just post it in the forum as available for users to add on if they like, or show them how to adjust it for their favorite models.
