If one holds a private pilot certificate in both airplanes and gliders, does the FAA issue two plastic cards that one would have to carry? What if one has commercial privileges in airplanes, but private in gliders?
What about being private in airplane, but sport in powered parachute? Some schools say that if one already has a private in airplane, then powered parachute at sport level would only be a logbook endorsement rather than a new piece of plastic. I was under the impression that logbook endorsements are generally things like the ability to fly a complex airplane, rather than being a sport level in a different category of aircraft.
