I’m against anytime other than FAA ATC-2152 time counting. If you weren’t actively moving airplanes with the FAA, it shouldn’t count at all.
Not in the discussion, but figured I’d mention them here.
Two other things:
Military hires shouldn’t have to buy back their time. It should be considered a “recruitment bonus” by the FAA and get added onto your retirement when you’re done.
I’ve been told that the union is pushing to move the mandatory retirement age to 57. That way, if you have 30+ years of governmental service and retire at 57, you’ll get 1.7% for every year of ATC with the FAA (you could even further that and include military/DOD time). I’d like to see 30 years, at any age, gets you retirement at 1.7% for every year of ATC.
