Another question. Throughtout all this time, I have been taught that the TAS has corrected the instrument, position, compressibility and density errors and I do understand them except for the density error. Why exactly does a lower density (higher density altitude) cause the TAS to be higher than the IAS/EAS?

I know that the instrument error is that of precision and defects from factory, position error is that atmospheric pressure intakes can have turbulance and compressibility error which occurs at usually above 250 knots and basically takes readings of the compressed air pressure rather than total pressure (which makes the readings increase).
