What a strange idea, pilots being required to fly their airplane to a visual landing on a clear blue day....who'd expect that?
Yup. Unfortunately that is the way aviation is going. More automation, more specialisation, less manual flying. So when called upon to go manual and visual, this may be the first time in, well, a couple of years. Suddenly the pressure is on.
Just as an example: old schoolers will use a 3x profile for the approach (300' per mile), with no additions here (sea level). Recently I asked for height call outs for an approach to a sea-level airport (as pre-briefed) and the f/o pulled out his iPhone. He had an App for that!
So I asked for the altitude at 8nm - "err hold on a minute..." (frantic keying)
So I asked for the altitude at 6nm - "err hold on a minute..." (frantic keying)
So I asked for the altitude at 4nm - "err hold on a minute..." (frantic keying)
Never did get an altitude check. This is not rocket science, you know.
