Factors affecting CAS when you fly into warmer air?
"What happens to your calibrated airspeed (CAS) or indicated airspeed (IAS) and true airspeed (TAS) if you fly at a constant CAS (IAS) into a warmer area?
The CAS (IAS) remains constant because CAS (IAS) is unaffected by temperature, whereas the TAS will increase because of the decrease in air density associated with warmer temperatures.
This above is an answer from my text book, though i would of thought that CAS would be affected by warmer air (temperature) as the air is less dense meaning less air going through the pitot tube?
