Cortilla. Interesting what you say about the brake cooling starting from brake release on stand. I used to fly for an operator where brakes were released with chocks in. Turn-rounds were not rapid; 45 - 60mins. I now fly for a rapid turn-round operator that always uses autobrakes, but reverse as well, and the SOP is brakes must always be set on stand. They say that there is no gain from releasing brakes on chocks. We operate into some short strips or short turn offs; operate on a tight schedule. I see many people use F30 but A/B 3. When asked why not F40 the answer is F30 is SOP, but we want to make a quick exit. On Carousel Airlines I wonder if brake cooling is such a hot topic. I'm not too practiced in it, and there is not enought time to delve into the charts anyway.
I've also tried to find Boeing's definition of a "quick turn-round". Unsuccessfully. Their table says that at these weights under normal 'quck turn-round' conditions etc.etc. there is no problem. Just how long are thye meaning?
