FAA current
This is my username, the FAA do know if you have a current medical - which gives an indication if you are current. The medical application also requires the number of hours flown in the last 6 months - another indication.
License is valid until I am no more. In my case, last valid medical 2002. Hence my IR (and other things) would not be valid.
Due to a rule change, I might be able to re-gain my medical - off to the opticians PM today as a next step on the route for a medical special issuance.
