However, talking from first hand experience, (single engine only) when the donk quits unexpectedly, your eyes are outside looking for a place to land and the lever is all the way down whilst holding last attitude. Never once did I look at the gauges or pay attention to lights and gongs etc. not enough time to look back inside...
