Thanks for the replies. It sounds like the crews do all kinds of unorthodox things to keep from overheating the brakes. Runway analysis tells you if you can stop, but if the analysis says you must use medium autobrakes -- not low -- why would you have to switch to low autobrakes once you touched down to prevent thermaling the tires? It seems to me that something is wrong if he can't leave medium autobrakes all the way down to a full stop.
