This thread has twisted around so much that I can't discern fact from opinion.
I'm still trying to figure out what procedures were being used vs what procedures were recommended by Airbus.
I presume that what is recommended and published is based on sound engineering principals and years of experience, so I'm still trying to read beyond any opinions that do not quote these exact procedures for this aircraft in a specified ground run test.
So, is this a judgemental problem associated with a lack of awareness in the cockpit, or is it a problem associated with bypassing a procedure? I tend to supspect the former based on the delay in applying braking action.
