Correcting indicated airspeed (IAS) for pressure and instrument error yields which speed?

Explanation:
A speed corrected for pressure- and instrument-related errors is called calibrated airspeed. The airspeed indicator reads IAS from the dynamic pressure in the pitot-static system, but that reading is affected by instrument tolerances and how the air flows around the aircraft (position errors). Applying corrections for those effects gives CAS, a more accurate speed reference that’s consistent for flight planning and performance. Beyond CAS, further corrections convert to equivalent airspeed (for compressibility effects) or true airspeed (for air density and altitude), but the correction described here specifically yields calibrated airspeed.
