Question

Can a pilot with a type-rating of a CRJ-200 also fly a CRJ-100 (or CRJ-700) with the same type-rating?

Answer 1

Yes, they can

The Cl-65 is a type that is shared by all those models of CRJ.  A pilot must only undergo "differences" training, which consists of basically a couple hours of systems classes and maybe a sim checkout, followed by a line check with a company check airman.

Answer 2

That is correct, and it is a big advantage for reducing training costs for a company that operates only CRJ's. However, the pilots still need "differences training", which can be up to three days, plus they must meet the currency requirements for make and model.
