True Airspeed (TAS) is an essential parameter in aircraft design and navigation. It represents the actual speed of an aircraft through the surrounding air and is crucial for accurate flight planning and navigation.
Formula: The formula for calculating True Airspeed is as follows:
- TAS is the True Airspeed (in knots or meters per second, depending on the unit system used).
- IAS is the Indicated Airspeed (in knots or meters per second).
- ρ0 is the standard sea-level air density (approximately 1.225 kg/m³ at 15°C at sea level).
- ρ is the actual air density (in kg/m³) at the aircraft’s current altitude and temperature.
