Why is the term "buoyancy" which is a term relating to objects in fluids being used for aircraft which fly in air (a gas)?
Because it is an acceptable term that is used all the time by some disciplines. Drawing parallels to nautical analogies is also done all the time.
buoy·an·cy The upward force that a fluid exerts on an object less dense than itself.
I respectfully disagree.
In the context used the term is not appropriate. If I use that reasoning then we would not need to create lift to fly we would just need to increase buoyancy. The discussion is not about lighter that air craft.
