Our (frozen) A-plan pays an annuity. If you take the lump sum payout and divide it by the monthly annuity payout, it is 13 years. This was based on old retirement age of 60, so I'd say about 73. Maybe?
Pilots that work to 65 will die at a younger age than those that retired at 60. A win win, they get used longer and collect less money during retirement.
