I understand how the system works, but i wondered if there was some data or info somewhere that stated whether or not, more heat was generated with min. or med. brakes. The amount of energy disipated is the same, but how its done, affects the amount of heat stored in the brakes. Some argue it's kind of like; which came first, the chicken or the egg?
one school of thought is; because using mediem brakes, they are applied for a shorter amount of time, thus creating less heat. The other school of thought is, min brakes create less friction. But from basic physics, and i mean basic, the total energy is the same dissipated.
I think using min brakes causes less wear but creates more heat energy stored in the brakes; and that mediem brakes wears more , but creates less heat!
Hell, this is why i'm asking? I can't seem to come up with a solid answer.
Just wondering, don't want this to become another US Air/Aer Lingus, ATC disaster.
