minus-squareBarqsHasBite@lemmy.calinkfedilinkarrow-up1·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-squareIDatedSuccubi@lemmy.worldlinkfedilinkarrow-up2·1 year agoIt is calculated according to the speed of sound at the altitude you’re in, and measured using a difference of pressure in the pitot tube.
minus-squarewolfpack86@lemmy.worldlinkfedilinkarrow-up1·1 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.
