Rolling Circle,
I looked damn hard in your post and could find ‘sod all to do with the question' asked there either. So should that have been seventeen responses to three answers?
Some twenty-five years ago I flew ‘conventional undercarriages' extensively and thought I knew it all. John Farley, your discourse has enlightened me on some concepts that I hadn't considered. But I will add that a frictionless runway may also result in a slow rotating ground-loop. I had an experience (in a Cessna 180) similar to yours (Ryan PT 22) on a smooth, clay strip in light drizzle. Just prior to the ground-loop I did sense that the wheels had locked up due to excessive braking given the surface conditions. The application of power (a brainwave) during the reverse roll certainly resulted in a reduced stopping distance! Fortunately in my case there were few spectators.
