Thanks for the feedback.
I didn't ask to clarify if it was the regs he's quoting or his ops manual, though i reckon it was the regs. I talked to his admin first, who also specified i gotta get a medical first before doing anything else. Plus apparently i am supposed to get a current FAA bi-annual flight review before proceeding with any conversion course (which is new to me, but i got no information on this - doesn't matter). Questioning any of their information quickly led to agitation, so i just refrained from it and accepted what they had to say.
He did say i could fly from the right seat, with an instructor on the left seat - again, saying it had something to do with the operating pilot having to be in the left seat with a valid medical. But whatever ... One can only wonder.
Thanks again
