Not relevant here, but it reminds me of an incident where I was starting the Nomad and was interrupted during the preflight check, leaving the power levers in reverse. Start up was normal, until the transfer to the power levers from the start control, and the engines both ran up at a quite fantastic rate to full reverse! Made the old ticker work at a fantastic rate too! I don't know who was shocked more, me or the ground engineer out front holding the fire bottle.
