So, hypothetically, if an intermittent short were to develop in a yoke mounted electric trim switch, and it would run nose down for a few seconds, stop run nose down again, stop. How many times would it need to do this before you called it a runaway? Or would you watch it do it again and again? Hey, look it's doing it again, too bad we don't have a checklist that would deal with this unwanted stab trim motion.
