minus-squareBarqsHasBitelinkfedilink2•edit-21 year agoDo they actually calculate mach that way when they say a plane can go mach 3? Or do they just use the speed of sound at 1 atm?
minus-square@[email protected]linkfedilink3•1 year agoI would hypothesize that the indicator for mach and air speed are decoupled from each other, as a true mach reading would likely give an indication of how hard a plane is working to push itself through the air. Just a guess though.
