NPPL was a self declaration requiring no medical examination, and plenty of proven safe history behind it, and similarly AOPA America see fit to make the following observation;
With the implementation of the Sport Pilot/Light Sport Aircraft Rule, the FAA has the drivers license as a basic form of establishing medical fitness. The use of the driver's license medical for sport pilots has not negatively impacted safety. There have been no accidents in this community related to medical deficiency.
Oh and by the way.......
To you too.
