737ng Rto
If you have a MEL released INOP reverse, it lever will be wired locked for sure. If you have a failure on the other engine, you won’t have reverse thrust for RTO. My SOP says that the PM should make the callout “speed-brake up or not up” during the RTO procedure. So assuming you leave it to work automatically. I agree we should deploy it manually BEFORE the reverse thrust is applied and that’s what I will do. SOP says also that you must leave the auto-brake RTO system to work until a complete stop as it is more efficient than maximum manual brake. On that I agree and the FCTM says so.
