Folks,
I think Squark7700 is on the right track.
There has been a lot of confusion in the introduction of the "new" FAA driver's license medical standards, they seem to be not working as designed ( as opposed to those of CASA, which were designed to not work) and the FAA has changes in the works.
Not to be confused with the new and quite radical FAR Part 23, which introduces certification standards for Standard Category aircraft that are established by the same mechanism as the ASTM "consensus" standards for Light Sport Aircraft.
So it is likely that multiple things are being mixed up, the Sports Pilot License, the Light Sport Aircraft certification standards, the new FAR 23 LSA like outcome or performance based certification standards, and fixing the new "PPL Light" medical standards.
Ain't acronyms wonderful, with the added delight of a plethora of different weight brackets.
Tootle pip!!
