I've always felt it my responsibility to maintain basic flying skills even though the airline doesn't. Routinely when it is appropriate use just the basic instruments and get your scan working again. Headed south climbing out to cross over Cuba on my 757 I would ignore all except standby attitude indicator, standby air speed, altimeter and whiskey compass while on a vector. If you never did it would you trust those instruments with a complete electrical failure.
If the PF on AF447 had done some of that would they still be flying today?
