No auto brakes on a contaminated RWY?

Since the 737 was certified in 1967, and SWA didn't start flying until 1973-ish, perhaps you could 'splain whatchoo mean.

I think he means that the "New Generation" 737s kept the old -200 overhead panel because SWA asked Boeing to keep things "standardized." That's the lore anyway; don't know how accurate it is.

Boeing wanted to certify the 737NG as a new type--SWA persuaded them through market forces to reconsider that idea.

Similarly, the 757/767 commonality is because of DL--Boeing just wanted to make the 767 and improve the 727-200ADV.

SWA does not deactivate the autobrakes. I saw them being used when I rode jumpseat in one of their 737-700s. They did have Boeing remove the autothrottles and VNAV mode on the autoflight.

RTO Autobrakes are currently used. Autobrakes for landing is being added.

According to this, they are not use

They were used on the landing when I was in the jumpseat landing in snow at PIT a couple of months ago.

I can believe that they don't routinely use them on dry runways of adequate length but they certainly can, and do, use them at the Captain's discretion.

According to the 737-700 AFM, max manual braking in all braking conditions produces a shorter stop than max autobrakes.

This is true in all current Boeing aircraft, not just the B737.

According to the 737-700 AFM, max manual braking in all braking conditions produces a shorter stop than max autobrakes.

However, Boeing recommends auto brakes for slippery and/or contaminated runways, short runways and crosswind landings. Certainly max manual braking has a shorter stop than max auto brakes, but that presumes max manual braking is initiated as soon as the wheels are on the deck and the throttles are retarded.

The preferred technique I believe is to initially utilize auto brakes and then over ride them with manual braking as needed.

early to be drawing conclusions as to the cause(s) of this accident.
