Another philosophy that a single pilot can adopt when under such a work load is to not conduct any non essential activities whilst within say 500 ft of an expected capture altitude, whether that be on auto pilot or being hand flown. Much like the Airlines do that usually limit their heads down activities (away from the watching the PFD)in the last 1000ft, this higher limit is due the higher ROD in a pressurized machine. The clue was the 1000ft to go to Alt chime.
It's all food for thought & makes us all reevaluate what we take for granted inside a cockpit when under certain higher work load times.
Technology has exploded in the light A/C field & makes it all exciting but in some ways it has also taken away the initial reason why we fly such basic machines in the first place, to have fun looking outside in the most simplistic way
Personally I don't have any fancy stuff in my own plane (old school, round dials, basic) other than an iPad which I only activate when going x country, my professional flying is a diff matter as I have no choice:-)
