Hi.

Always during taxi, at less than 25 knots as expected, even if I don't use brakes, autobrakes change from RTO to DISARM.

As you set autobrakes to RTO just after starting engines, i.e. before taxi as per checklist procedures, it is really not a good idea to find out you won't have autobrakes in a rejected take off.

Anybody else experiencing the same problem?
