Chicago runway too slick at Crash

[HighSpeedClimb]

guess they are still looking into that. I was just pointing out to all those folks that claim "we are cowboys".

This was definaltely not a "Cowboy" thing. From some Boeing classes I went to, braking action reports are never correct to the exact condition. If its reported Fair its bad. One thing I did learn about reversers and Autobrakes is that if you let the autobrake system slow the a/c without overriding the brakes manually, and then add reversers, the brakes are adjusted to keep the same deceleration you had prior to deployment. In other words, landing with Autobrakes at 1,2,3 without overriding, reversers do nothing. These guys definately used full brakes though, as I'm sure any of us would have done.
We can learn a lot about these incidents to help each and everyone of us while out on the line.

The end of the runway alway has less traction and is "slicker" then the touchdown zone. AS for Southwest pilots being cowboys, I very much disagree with that, I consider them the 737 experts and they all know how to fly an airplane.

The system, at least in the A/C I fly, is not perfect. If you rapidly reduce RT to idle at 80kts you can feel the A/C rate of deceleration reduce, then feel the brakes come back in and increase the rate of deceleration once again.

Interesting info on the autobrakes/thrust reverser deployment can be found in the human factors info released by the NTSB.

If I am reading it correctly it would appear that the information was obtained from SWA's own testing prior to implementing autobrake use for line ops.

For what its worth, a common theme, apparently, among pilots making autobrake assisted landings for the first time was either forgetting to deploy thrust reversers or late deployement of reversers (see post evaluation comments on pages 14-15).

For the accident captain, it was his first landing using autobrakes.
