Speaking only of intrinsic and extraneous cognitive load oversimplifies things. This works for tasks of pilots (see e.g. NASATLX scores).
However, if new information that needs to be learned is in the game there is also germane cognitive load [0]. It is a nice theory, however, practically there is unfortunately no easy way to separate them and look at them totally independently.
