You're all probably bored of me saying this, but an easy system to encourage manual flying would be where we have to perform and record a certain number of manually flown, raw data manual thrust approaches every six months, as part of normal line flying.
We used to have to do this for Autolands, and we kept a personal record of them which was checked at every SIM.
A similar thing should be brought in for manually flown raw data approaches. Obviously they would only be expected to be performed in good weather, but it might help drag us out of our collective "laziness" (and I hold my hand up here too.)
