Experience?
'Hours/age is an indicator' says Fade To Gray. Yes, but it's not a totally precise tool. When I was in my early 40s I had 3000 hours, so perhaps you might consider me inexperienced. But nearly all of that had been military, half of it intensive, short, teaching sorties. Even on 4-jets we had the luxury of adding a couple of extra approaches at the end of most trips. It's surely not too simplistic to say that time spent on takeoffs and landings contributes more to useful experience than flying S&L at FL 300. That's not meant to undervalue the undoubted competence of the 15,000 hour airline pilot, but don't let's pretend that a man with 'only' 3,000 hours is necessarily a newbie.
