Got to say this data link business seems very curious to me.
It seems that every aircraft is being designed to provide the pilot with less and less natural cues.
I don't fly the Airbus but guess that because of many design features such as no moving throttles, the pilot has to use his eyes to see the engine power change. (No Airbus bashing please just an easy aircraft to use as an example)
The same goes for the side stick not moving.
And now they want to take away a very valuable primary sense of a pilot, his hearing and replace it with looking at further instructions on the MFD.
Soon our eyes will be so over-loaded whilst our hands and ears just sit bone idle. Sounds like a bad move to me.
