Hi, for your question ,exactly no not at all,A300 B4 series are three men cocpits.Everyone has own tasks in the cocpit.You can not fly a A300 200 B4 with two pilots.There got to be a feo.Only A300 FFCC is a two man cockpit as A300-600 series but it is different from A300-600.Flight instruments are different,they are analog in A300 B4 and FFCC series.In FFCC series the feo's panel shared in the head up display and in the pedestal.I flew FFCC and currently type rated on A300 B4.The type ratings are different as my friends told in the page.If you have A300-600 type rating you can fly A300-600 and A310 as well.But if you have A300 B4 type rating you can fly A300 B4 and if you take difference course (it is 5 hours or something groundschool and one sim session) you can fly A300 FFCC.
I wish i could have explained your question.Take care bye.
