JJ Flyer-and how about throttles which move? I've once or twice seen throttles very slowly go forward when setting a higher altitude and pushing the VNAV button years ago on the 757-almost no response. You have two good sources of feedback, instead of just staring at the EPRs etc. It was much easier to realize that the autopilot might need to be disconnected; reset both flt. director switches and an autopilot button (one of three) + VNAV and hdg select.
