Kaptan Balus,
The 744/744F/748F pilots are not able to fly the 777 at the same time.
FARNBOROUGH: The A350 flightdeck - pilots at home in the future
The A350 flightdeck has evolved from the A380's, but an A330 pilot would feel totally at home in it. Rather than introducing radical new ideas, the manufacturer has worked on improving the accessibility of the unprecedented amount of information available to the crews, the ease of use of all the avionics and systems, and the clarity and intuitiveness of displays so as to maximise crew situational awareness.
The way flight and systems information is presented to the crew is fundamentally the same as it is in an A330/A340 series aircraft, because although Airbus wants to advance, it also wants to make cross-crew-qualification (CCQ) with other types in its stable easy and cheap.
