Hi! I've had 3 1/2 Hours of flying lessons now (Love it!!!!) but I'm getting stuck into the theory, I've got stuck AGAIN, I'm going in for my LAPL due to my age & will never use it for a career & come across a section in my book explaining MACH speeds, speed of sound @ 15* @ MSL = 761mls/hr 661kts/hr, do I need to be able to calculate part MACH speeds @ the speeds that I'll be flying at for the LAPL, 100kts (MACH 0.15 I think & MSL 15*)? Also, how do you use the Jeppesen CR3 to calculate MACH speeds? There's a section of it showing MACH speeds but they just don't make sense, obviously something to do with CAS & Temperature, Cheers, Ian
