Something that occurred to me while driving home last night. The car has a six speed manual, which means a fair amount of the time I only have one hand on the wheel.
To the best of my knowledge, SOP (at least on Boeing) is to keep one hand on the throttles and one on the column during approach. I've been on the flight deck for countless approaches during flight test, and many, many simulator sessions, and that's what every pilot has done.
By accounts, the Asiana PF was having to pull back with as much as 80 lbs. force as his speed decayed. I dare say most people would be hard pressed to apply 80 lbs. to the control column with one hand on the throttles...
