I don’t understand the weird arguments going on here. Hovering means to stay in one place in the air. It says nothing about air speed. Ground is the only reference needed for “in place”.

I'm curious what would define hovering as if it is not "ground speed zero"?

Air speed zero? Otherwise I’ve seen some Cessnas hover :)

Are you "standing still" if you're sprinting at full pace, out of breath, heart pounding, but feet slipping on an icy slope so you have ground speed zero?

Is it still commenting if I’m “just” typing this and hitting enter?

Yes... That's exactly what it is?

saying something can hover usually implies that it can have a ground speed of 0 at an air speed of 0. If you leave out the air speed requirement then anything that can fly can hover

That doesn’t make sense. If something only hovers at air speed zero along with ground speed zero, then as soon as any wind whatsoever picks up, then that something is no longer hovering by your definition, even if it maintains the same place in the air. Hovering means to stay in the same place in the air. It doesn’t say anything about air speed, which is the delta between wind speed and ground speed.

Debatable at least..
