Some companies request that you engage A/P A/T above a certain FL on T/O, same on landing thus making hand flying time very limited. However in some cases it's legal to make a flight with a defective A/T A/P: Then good luck because with the F/A rolling the trolleys along the aisle and PAX getting up at weewee time you'll have to be a pro with trims. Unless you're flying a bus or another fly by wire gadget. Did you knew that the bus had a very simple cockpit? 3 buttons= Climb, Land and coffee.
So if you do the math not that much and I would say around 10 minutes per leg...
