I understand how temperature (directly related to desnity, or number of molocules of air per volume) is related to Alitmeter errors, based on the shrinking and expanding of the atmosphere for changing temperatures. I also understnad that the ASI is based on how much air is being rammed into the pitot tube, more molocules is equal to more pressure, so a higher airspeeed is indicated. I have rote knowledge of 'with higher tmep comes higher true airseeed,' but that doesnt sit right with me. What I'm confused on, is HOW this all works. If the ASI is based on the differenctial pressures seen in the static and pitot, with a change in temperature, both densities are changing. The warmer air means less pressure in the pitot AS WELL AS the static, so I would think that they would both see the same change, and TAS versus IAS would not change?
What am i missing?
sorry for the poor wording.
