I do my best to do all of the above. Normally autopilot comes on when there's no more turns for the next hundred miles or so, or if i'm still enjoying the view and the control, i'll let her go till FL180. Auto pilot off when i'm going to do a visual approach, or instrument approach and i feel the workload is low enough i won't be to distracted. honestly speaking, for myself, the flying hasn't gotten old (although there are legs i wish i could just jump out of the plane) but the lifestyle has been very very slowly wearing on me....After reading Bryris' long article before this....i think he feels the same thing.
