Is that what it is?...250 turns of the trim wheel from stop to stop? That info wasn't available anywhere in the AMM, the FCOM or even the FCTM. Like some, I wondered how many turns it was, so thanks.
Having been on the jumpiest of a classic or NG (never been in a MAX), those trim wheels seemed to turn quite a lot even for very short bursts of trim input, so 250 is quite credible.
