Relating to the science of gases at rest or the principles of lighter-than-air flight.
From 'aerostat' with the adjective suffix '-ic.' This term emerged in the 18th century as scientists studied the physics of buoyancy and atmospheric pressure.
Aerostatic principles are why hot air rises—it's less dense, so it floats upward through denser cold air, the same way a helium balloon floats. Understanding this simple physics led to the first human flights centuries before airplanes were invented.
