Having to renew a special issuance 1st class cert the last five years of my career was onerous and expensive even though I was a picture of health and the outcome was never in doubt. Now in retirement and on BasicMed I keep as fit and I take the same medical tests at the same intervals I always took for the special issuance but don’t have to go through an expensive FAA whisperer to get the FAA to bless the results. My specialist interprets and blesses the results now and I am better educated and no less safe than when I was renewing a SI 1st class.
