Yes, it doesn’t say “must”. It also doesn’t say “must not”. Given that there is a reminder there that it CAN be used prior to cutout, what would be the reason for NOT using it to fully counter the MCAS? Aside from the design failures themselves, a key to this accident is why weren’t they trimming up as far as they needed to? I know it’s been asked numerous times already in this thread, but it is perplexing.
BTW, it does say at the very start of the trim runaway (in the AD not the abbreviated memory item procedure) to disconnect the autopilot and control pitch with column and electric trim. That’s not a “may” or “can”.
