Jerry:
I might be able to help in the presentation for the spouses regarding handling the plane in the event the pilot becomes unable to do so.
I have a document which I keep on the plane and alert passengers about on doing this. It tells a non-pilot how to communicate with ATC, how to control the plane and, after some practice in the air (slow descents, slow climbs, slow turns), how to land. You can see more on this in my backup website at
www.SkymasterUS.com on the link titled "Pilot is Unconscious".
