Thanks for your replies guys.
I am however contemplating a simpler scenario;
A pilot, operating two types, both of which fall under a class rating, not type rating.
Typical for a small piston operation, where you wouldn't fly a larger aircraft than lets say a Piper Navajo and a Cessna 172.
Do you follow the same path as a pilot who maintains currency on two very different types of aircraft where two individual type ratings are required?
