How is calibrated airspeed calculated
Web10 okt. 2024 · The most accurate method is to use a conventional or electronic flight computer. A second method, which is a rule of thumb, provides the approximate … Since the airspeed indicator capsule responds to impact pressure, CAS is defined as a function of impact pressure alone. Static pressure and temperature appear as fixed coefficients defined by convention as standard sea level values. It so happens that the speed of sound is a direct function of temperature, so instead of a standard temperature, we can define a standard speed of sound. For subsonic speeds, CAS is calculated as:
