David, thanks for the info. My experience is with the Navy Mk 5, the British Mk IX, and IX-A. The averagers sure help. I gather Fred Noonan had an A-6 or A-7 which get an average with a trigger operared pencil that marks a drum. I think at least one member of the forum has used an A type in flight.
