I am playing around with data collected during a flight. I would like to find out the (real, not ISA) ambient air pressure for each data point, since it is not reported in the spread sheet containing my flight data.
I have the following data for different time points, but do not know how to (if even possible) derive from this the ambient air pressure:
Airspeed ktas and kcas
Static air temperature
Total air temperature
Pressure at the ground / surface pressure
I would be thankful for a solution or any tips for literature helpful to solve this.
Under the following link I found a formula I could rearrange but I believe this would return the pressure in the standard atmosphere... https://www.weather.gov/media/epz/wxcalc/pressureAltitude.pdf
