There’s a lot that goes into deciding how and what tasks to do, how quickly, at what points in flight, and those numbers change as winds, weather, traffic, and fuel burn changes. Each flight, the pilots need to basically take all the factors going into the flight (# passengers, bags, cargo weight, routing, taxi time, and so on) to figure out how much fuel to use, what particular climb profile they’ll use, and a bunch more. It makes sense that there’d be a “clean cockpit” magic button to push, but not only would the magic button need to be tested in every aspect of flight, in every configuration, in every combination of working and broken sensors… but airplanes are flippin’ complex, and flying modern airliners as part of an airline is even more complex.
