I had a buddy that was going into one of the shorter runways around LA (the one where SWA ran off the end.) He was flying right seat and they set up for a flaps 40 landing and decided for the heck of it to select Auto Brakes 3. When they touched down and the brakes activated it was really impressive. So impressive that the passengers were screaming and my buddy and his captain decided not to pick that setting again.
So if a 737 driver really wanted to come to a stop in minimum (ie emergency) distance, what can they really do when passenger comfort is no longer an issue?
