Funny thing about those UAV pilots, though.
You put them in charge of an aircraft full of people, make them responsible for the lives they hold in their hands, and guess how much you're going to have to pay them? About as much as an onboard pilot....
A single UAV/UAS pilot can be in charge of several aircraft.
Or you can assign UAS pilots for specific tasks like approach and landings, take-off up to 5000ft, and en-route. En-route, computers can do most, UAS pilots could then be made to respond to warnings/cautions.
I imagine that you could manage 30 flights with only 10 UAS pilots.
With GPS, 4D situation data and doppler, a UAS pilot could probably do the same thing as the Hudson ditching but in thick fog.
The same for the Ciampino forced landing.
A computer can be made sensitive enough to land you a B737 in a 50kts, gusts 75kts crosswind automatically.
The presence of pilots in the cockpit has been limiting automation.
