Hi Al,
You make an excellent point on the single failure
point.  I've been trying to come up with a way to
eliminate the problem, but outside of going to 2
switches, I'm not sure how to do it. Even with 2
switches the one for the engine is still a single
failure point for the engine.  The emergency checklist is also a good idea.  I'm
going to check today, I think that I already have one
with my preflight checklist.  A placard for engine out
is probably better though, rather than trying to find
a paper copy during an emergency.
