CRP-5: How to calculate True Airspeed (TAS)
Part 5 of my CRP5 series, showing the way to use a CRP-5 to calculate speed True Airspeed using the temperature and pressure altitude. I have also given a fairly straight forward explanation into what the difference is between Indicated airspeed (IAS), Calibrated Airspeed (CAS), and True Airspeed (TAS).
