Comment (justification):
In the calculation of Ambient air density Eq. 8.5 iit says that 273.15 must be subtracted from the temperature. It should say that 273.15 must be added to the temperature, to get the temperature in Kelvin
Proposed Change:
It should say that 273.15 must be added to the temperature, to get the temperature in Kelvin
