Rivet gun;
Compressibility is not an error, but a physical characteristic of air. It affects the dynamic pressure in the pitot tube that drives a pneumatic ASI. Therefore airworthiness regulations require operational speeds such as V2 and Vref to be specified in CAS (at all altitudes). What would be the benefit of displaying EAS?
