"Slacktide" posted a question (post 1337) on the Indonesian 610 thread asking why stabiliser cut out switches had been relabelled. As far as I could see, nobody had any views, just though I'd ask again as I'm also curious!

It appears that the two trim systems which were labeled "Main Elect" and "Autopilot" on the NG are now labeled "Pri" and "B/U" on the Max. One would ASSume that this means Primary and Backup. It would be useful to know if there are any operational changes to the system besides the labels. It is unlikely that they would have made have made a change to the labels without a reason.
