    Let’s try the Socratic method…

    Does the airplane perform better in denser or thinner air?

    Which air is denser when the altimeter setting is “higher or lower than standard”?

    Expanding this to real world safety – what are people concerned about when a high density altitude is reported on ASOS/AWOS?
