Hi vilas,
Hopefully somebody should have done the preliminary cockpit preparation and the walkaround, but it could happen indeed. What about doing the flight controls check with the autobrake max above 40 kt during taxi ? Upon extension of the ground spoilers the system will trigger the autobrake max as well. We shouldn't be taxing at 40 kt but I can see it as a realistic scenario hence the need to arm the autobrake only after the flt controls check.
By the way this has nothing to do with legality
