TMN
I am wondering if anyone can shed some light on a question I have.
I sat flight planning a couple of months ago unsuccessfully and I ‘m re-sitting it again next week. In my last exam I had 2-3 questions where the cruise schedule in the exam information was given as a True Mach Number. For example cruising at 0.8 TMN and FL 350, OAT is -60C.
The flight planning data in the B727 Manual is referenced to Indicated Mach Number so obviously a conversion is needed.
I have been through the theory notes that I am using and have found no mention of True Mach Number or how to convert it to Indicated Mach Number. I also spent some time going through the CR3 manual.
Can anyone enlighten me on how to convert True Mach Number to Indicated using the CR3 or otherwise?
Cheers in advance,
