correction.. y = gamma :-)
where did you get: Vsound in air = 331.4 + 0.6 Tc m/s?
The way i've learned the sound of minor pressure disturbances (so.. e.g. sound) is by this formula:
a = sqroot(yRT), where R = 287.05, T = temperature, and y (lamda) = 1.4
then you calculate the mach number by dividing the actual airspeed by this 'speed of sound':
M = V/a
So as you say, ...
Can anybody tell me what type of A340 China Eastern operates? I used to live in Shanghai when i was still in high school and i can remember flying from there to Beijing to Belgium (I'm Dutch) in A340's and it would be interesting for me to know what type they flew.
