If you choose to use the auto-pilot all the time, I can gaurantee your skills will erode.
Any below average pilot can "fly" an auto-pilot and look passable as long as they do the minimum SOP's. Auto-pilots have their place, but if you don't choose to hand fly once in a while on a quiet sector, you are doing no one any favors. This ain't a hard job folks. hand fly your departures and arrivals when you can, push yourself just a little bit regularly, and its no big deal. If you never do it, you will have a tough time when you have to do it. Stop the whining, fly the plane! People spend more time screwing around with their mobiles than they do honing their skills that will benefit their carreers.
