About flying manual, commercial pilots like to do as much of it as they can, to stay in practice. Most of them fly the climb out after takeoff manually most of the way to height, for example. But when it comes to landing (depending on how well the airport they're flying to is equipped) they are normally REQUIRED by company and air safety regulations to use the auto systems. I believe that they have to apply for special permission to practise landing manually, and only usually get it a couple of times a month.
Yes this is the case in UK airspace. Where an airfield has an ILS facility it is deemed to be used by ALL pilots. Pilots can ask for a visual approach if the weather is VMC but would only be granted permission if the airport was not busy at the time..
I was on an Easyjet flight into Luton when P2 took over and nearly lost the a/c!!! It was his first time out of the 737 simulator!!!!! P1 put it back onto the AP and we landed safely!!
