Convert indicated airspeed to calibrated airspeed using correction values from your aircraft charts.
Calculate CAS
What Is Calibrated Airspeed?
Calibrated airspeed (CAS) is indicated airspeed corrected for instrument and position errors.
It represents a more accurate measure of airspeed than raw indicated airspeed.
Why Pilots Use CAS
Improve airspeed accuracy
Reference aircraft performance charts
Better understand true flight conditions
Training and checkride preparation
Important Note
Correction values vary by aircraft and configuration. Always refer to your POH or AFM
for accurate calibration data.
