I think i've read that the B787 has a common type rating with the B767 and B777. But I also think I've read that pilots are only allowed to fly two types of aircraft at a time...
So when they go to fly the 787, do they have to give up one of the their ratings if say they were previously allowed to fly the 767 and 777? Would the same still apply for say a B757 and B767 which have very similar flightdecks?
EASA and FAA perspectives would be appreciated :)
