Why do we actually worry about hot brakes?
Ans: To avoid fuse plug meltdown during RTO on your subsequent sector.
Anyone who has been using Brakes 1/2/3 WITHOUT reversers and hasn't had any problems has not yet done a high-speed RTO after a quick turn-around.
What about idle reverse? I haven't seen any Boeing table that factors that in, only NO REVERSE. There's a world of difference there. Are inter/extrapolations valid? That assumes values are linear. They could be exponential, though.
I agree with the other guys whose technique is to use idle reverse and let the brake energy dissipate before applying manual braking (approx 80kts). Runway permitting, of course.
Critical runway? Our prime responsibility is flight safety, so noise inconvenience can just go hang.
