11 months ago@gedaliyah yes. Mach number is defined in terms of the local speed of sound, and that varies depending on pressure and temperature. I don’t know exactly how much, but several percent at least?
@ericbomb Don’t get one now to make up for what you skipped back then, get one now as a checkup for what you might need to fix and for what you need to keep an eye on.
