?Mizuiro- chan? asked:


When an airplane (or any sort of motorized aircraft, for that matter) is flying, they have a gage that tells them the altitude they are at, and if they are losing or gaining altitude. It also flashes an emergency light if they are losing altitude too fast. How does the plane’s systems know?
