investigating Sonic Boom does not occur at Mach 1

[broderbund67]

Hi,

I did a flight at 20,000ft, wind 284-062. Flying hdg 325 the sonic boom occurs at M1.05. Flying hdg 159 it occurs at M0.93.

I would expect the sound effect to happen at M1.0?

See attached track.

Thanks

Bumping this because there's still something not right with the sonic boom effect. It should occur at M1.0 but it often occurs at M0.96 or thereabouts, regardless of module being flown.

Hi, 

It might be a mismatch between atmosphere models used by the sound engine and the aircraft. We will try to reproduce. 

thank you
