That's interesting. The airline I fly for teaches that autobrakes in maximum are more efficient than human braking and in these circumstances if it were me in this guys shoes I would be cited for not using autobrakes!
Of course, the equipment I fly is different so maybe the 737 autobrakes are not very effective.
I think the autobrakes should be applied, but Southwest doesn't and I'm not sure if that is part of their training. My airline didn't have the -700's, not sure of the policy. Is that runway Cat II?
I'm thinking that he missed a setting, though. If he cranked it up under those conditions, he could have a problem on his hands. I've seen guys set brakes to MAX thinking they were in RTO. I bet he though he could get a little help from a 1 or 2 just in case at that runway.
Don't the "Autobrakes" ensure that Anti Skid id also in effect ?
