Mmmmm ...
I think pressing the Cat A button will
also select 102%Nr ....
......
One problem I feel is that it requires the pilot's head to be in the instruments for the whole takeoff procedure......
And perhaps that problem might be overcome with the 2 crew "team approach" ... and anyway should be no more of problem than the handling pilot having his head outside and NOT seeing something go wrong 'inside' the a/c.
Bring it on ...
