I’m of the opinion that as long as you can do the job and want to, then you’re retirement date is at your discretion. We have folks that shouldn’t be in either seat at 40 never mind 70. Basely if the pilot can maintain the standard and the medical then age shouldn’t be a factor as it’s just a number. I suspect only half of the pilots’ at 60 really want to go on as we all age differently. And then for how long? Maybe another year or two, part- time, whatever...
There are folks out there that probably can do an excellent job at 80 and some that should quit at 50.
