Framer has this right. Its a combination of excellent basic (raw data) flying skills and a hunger to keep on learning the tech stuff. A guy who has a power failure but still fly a standby instrument raw data approach where "the outcome is never in doubt"... but also knows his aeroplane / environment/ FMC(S) operation intimately. Human factors appreciation should be a given!
Flying is a degradeable skill....don't use it you will lose it. No one can claim to meet your thread title requirments by excelling in either area.
