With all the recording of the minute details of each flight now done, surely the amount of hand-flying done by each pilot at cruising level is already available.
In an earlier contribution I suggested that this might be called "447 Time", just to remind pilots of what MAY have been a contributing factor. It could or should, be practiced, at least initially, in areas and at times with the agreement of ATC.
As a very very new Second Officer I was expected and required by my Captains to be able to do just this, admittedly prior to RVSM, for alternate hours of cruising flight.
I was told " NOT TO WANDER ABOUT !"
I suppose that I must have met their standards. As a newish F/O i was the only other pilot on board, flying via Keflavik, Gander and Bermuda to Kingston and hand-flying for 4 hours on each leg (A/P U/S).
One of the 36 passengers weighed "27 stone". We saw that he HAD to be in TWO PLACES AT ONCE, but with an extra seat belt.
Flight time limitations came some years later.
