Which value is obtained by correcting indicated airspeed for instrument and installation errors?

Explanation:
Calibrated Airspeed is obtained by correcting indicated airspeed for instrument and installation errors. The airspeed indicator reads a value based on dynamic pressure, but that reading can be biased by calibration and mounting errors. Applying the instrument and installation corrections removes those biases, giving a speed that reflects the actual dynamic pressure without instrument faults. True Airspeed and Equivalent Airspeed require additional corrections for air density and compressibility, respectively, beyond just instrument corrections.
