I think a more recent study is in order to discuss this topic as it relates to increasing retirement age.
During the time of the study, 1968-1993, I'd like to see a chart showing average block time flown per year.
That would be a simple way to account for vacation, days off and the amount of actual work done in the career.
Although I'm not suggesting that airline pilots are now dying in less time after retirement than they were in this study, I do think that a few factors have changed that could tilt the scale the other way:
- Up to five more years of flying
- Pilots are now averaging more block hours per year than years past
- Commuting to one's base not only probably more prevalent, but likely more difficult at times
Of course, there are several things that could cancel the above factors out:
- Many people are eating healthier now, and healthy options on the road are probably also a bit easier to find
- Less smokers
- It is definitively known that heavy drinking over years is also not healthy
- Seems to be more of the population getting some exercise on a weekly basis (or at least, the facts are clearly out as to how it is a health/longevity advantage)
- Some flights that used to be 11 hours and 45 minutes with three pilots in the cockpit the whole time, are now staffed in a way that each will get a few hours in a rest bunk/seat and at least get some amount of sleep.
