The autopilot trim command on 737NG is either the trim while the autopilot is engaged, or the trim command from the Speed Trim System (STS). MCAS issues commands on the same autopilot interface and would be inhibited by this cutout switch if it were on 737MAX.
For reasons I have yet to understand, Boeing changed the cutout switches on 737MAX to PRI and B/U. In this configuration, both cutout switches are thrown in any runaway situation,
With the 737NG cutout switches, MCAS runaway is stopped by just throwing the autopilot cutout switch, leaving electric trim fully operable.
With the 737MAX cutout switches, MCAS runaway is stopped by throwing both switches, losing electric trim altogether. In this case, the flight crew must rely on manual trim via turning the trim wheel/crank. As discussed above, the manual crank can bind up, making flying much more difficult.

Tiens ?! mais ne sont concernés par le MCAS que les MAX - 8 et - 9 ?...

Pour ajouter au débat...A pilot for a US airline told managers months before October’s Lion Air crash in Indonesia that he was uncomfortable with the level of training he had received before he was scheduled to fly the Boeing 737 Max for the first time. But when he asked for more training, he faced difficulties in getting it—and even a form of reprimand.
....
The pilot Quartz spoke to has about two decades experience with his current airline, and additional experience beyond that. He was assigned a two-hour video tutorial, in line with the FAA’s recommendation for pilots certified to fly an earlier variant of the 737, to which the 737 Max is related.
“After completing it, over the next couple of days I got to thinking that, you know, they said it wasn’t a different airplane, it was just the same airplane with some differences,” he said. “But I went back over my notes, and I went back in the iPad and reviewed some of the information and I realized it was actually, it was the same airframe, but it had different instrumentation, some of the things were in different places, it sat on the ground differently, and it was just a different airplane.”

Sauf à refaire entièrement le système de commandes du MAX et à éliminer les câbles, je ne vois pas comment s'inspirer des avions modernes.Beochien a écrit:J'ajoute que les B767-777-787, ont un autre système de vérin de queue, qui semble ne jamais poser de PB, il serait peut être temps d'y penser ??
