That's not what the engineers say.

I am an engineer and have the degree to prove it and I totally agree
with him, so stuff it.

Under some conditions, low air speeds is one of them, air can be
treated like it is an imcompressible fluid.

The difference between TAS and EAS is only about 13% even at Mach 1. Since
small aircraft come nowhere near to Mach 1, for all practical purposes air is
incompressible for most calculations.

Word salad that shows you don't get the concept.

At low airspeed, the equations for incompressible fluid flow are close
enough to what actually happens that they can be used for practical
calculations.

This does not mean that air "acts like an incompressible fluid" in any
way, shape, or form.

Obviously air, being a gas, can be compressed, but taking that into account at
low speeds greatly complicates the calculations, and the final result isn't
significantly different.

Finally, the light comes on...

Well, gee-whiz, you backed into a place where you are finally correct.

Aren't you great?

The light was always on, but it's hard to see through heavily tinted glasses.

Wrong again, Anthony! There is no King of England.
