The 300c limit on the Airbus brakes before takeoff is because the Airbus has no Wheel Wheel Fire detection system. It has nothing to do with the performance of the Brakes when they get warm.
Ok
Oh and that is a "
ground cooling table"
If that table says 3 hrs on the ground then it would be 10 mins in the air!!
So, not applicable in the air with a 200 kts breeze!!
