Since it seems to be a slow day to catch this much attention, here is a crappy vid on the 777 brake test. I have the 1 hour original recorded from a TV show, but this has the essentials of the validation test. Full load, rejected takeoff, 5 minute wait at the end, and pass criteria of having the ability to jack up the plane repair and return to service with only gear damage. Expensive test, required by the airline!

For our RV technology level and specifics of mass, velocity and braking required, DanH nailed it, disc mass is a primary solution parameter. I imagine if we had glass wings, the tolerance for a wheel fire would be a lot less.

Lord Kelvin:
I often say that when you can measure what you are speaking about,
and express it in numbers, you know something about it; but when you
cannot measure it, when you cannot express it in numbers, your knowledge
is of a meager and unsatisfactory kind.
