So true what the man says, but airspace today is not designed around hand flying. Try a missed approach at some airports (Macau runway 34), it's a challenge simply reading it out let alone doing it manually even in an EFIS equipped aircraft. Analogue instruments ? Good luck
I have been picked up by Hong Kong ATC because our mode C altitude read out was ONE HUNDRED FEET off the assigned level. RVSM, RNP and saturated airspace around major airports all favour automatics.
Flying a B707 into New York Idlewild airport in the early 1960s was the time for manual flying. Complex arrival into Hong Kong, number nine in sequence ? I'd rather everyone was using their automatics to their full capability.
