The information I'm aware of so far is that the Lion Air flight crew did repeatedly attempt to adjust the trim, but it's not known if they used the cutout switches. A previous flight with the same aircraft did experience runaway trim,and the cutouts were used before the problem became unrecoverable. I find the design of this system shockingly ill-considered. At the very least, it should require input from both sensors and not activate if the sensors disagree. It seems to me a better system would be to automatically add some nose-down trim if the pilot applies full forward pressure on the stick since the primary underlying concern is insufficient elevator authority in certain impending stall conditions for that standard pilot response to be effective.
