In the context of aircraft said to have a "flying tail", what does
"flying" mean? I mean, if the tail isn't flying, neither is the
airplane, right?

There are other efforts in this newsgroup to redefine what "flying" means.

However, I think your example takes its meaning from historic naval and/or
architectural usages, where one "flies" a sail or a superstructure. It
describes a method of suspension, so no motion is required of the item
being "flown".
