The formula to calculate the calibrated air speed is:
\[ CAS = IAS + (TAS - IAS) \]
Where:
Calibrated air speed (CAS) is the indicated air speed corrected for instrument and position error. It is a more accurate representation of the aircraft’s speed through the air compared to indicated air speed (IAS), which can be affected by various factors such as instrument inaccuracies and the position of the airspeed sensor on the aircraft. CAS is crucial for accurate navigation and performance calculations, especially during takeoff, landing, and when flying at low speeds.
Let's assume the following values:
Using the formula:
\[ CAS = 150 + (160 - 150) = 160 \]
The Calibrated Air Speed is 160 units.
