When I got my 1900 type I had a person sitting in the right seat reading checklists, radio work and general co-pilot stuff. When my new certificate was typed up it stated "Second in Command required" IF that person had not been in the seat reading checklists and helping it would have not had that "SIC required" on it. Upon my next visit for recurrent I asked for another check ride without a SIC and the "SIC required" was removed"
So the ride itself was no different other than now you had to flip the flaps and grab the gear?
