It's scary that in the recent AF 330 and Indonesia 320 accidents, the pilots were unable to hand fly aircraft with basic controls, had a full set of instruments, fully serviceable engines, but no auto throttle, and presumably ground speed from the GPS.
Looks like we're going the same way.
When was the last time you hand flew a commercial jet transport (Airbus or Boeing) at cruise altitude? It's not like throwing it around at 3000 feet on the ILS.
