// If an operator/hobbyist/enthusiast isn't "piloting" the aircraft, then what term would you use?
Playing? It's a toy, after all. "I'm playing with my drone."
To me, "pilot" means someone inside an aircraft controlling it. Once they're in the air, their life is in danger. RC stick wanker is not a pilot.
I jump from airplanes and off of big mountains wearing a wingsuit, and although the term "wingsuit pilot" is common these days, to me it sounds funny as "piloting" my own body is nonsense. (I'm piloting this pilot which is myself?) Wingsuit flyer, wingsuit jumper - yes, but not pilot. It doesn't matter what the not-keeping-with-times Webster or we-want-to-control-everything FAA calls it; it's what makes sense.
