11. On the basis of company procedures and flight training criteria, the airplane’s touchdown at 2,900 feet down the 6,017-foot runway was an unacceptably long landing.
12. The flight crewmembers did not use reverse thrust and braking to their maximum effectiveness; if they had done so, the airplane would likely have stopped before the end of the runway.
13. Specific training for pilots in applying maximum braking and maximum reverse thrust on contaminated runways until a safe stop is ensured would reinforce the skills needed to successfully accomplish such landings.
Failing to use the brakes has been a factor in other over-run mishaps as well, and has been previously identified as a training failure. It's simple in theory--full brake application until one stops. The problem is that one feels a lot of feedback through one's feet and seat that is uncomfortable, which leads one to ease off the brakes. Everything smooths out, but now the aircraft is no longer decelerating effectively.
There's a time to be smooth, and a time to make the aircraft perform. Anticipate the fact the maximum performance braking on a contaminated runway feels different, be ready for it, and you won't react by coming off the brakes.
