Density Altitude and human performance

[PaulMillner]

That is know as density altitude, and affects horses, cattle, humans, planes, cars, dogs, and more.

You're missing the distinction. Inside your lungs, it's always 98 degrees F, and 100% humidity. So your lung performance is not affected by *density* altitude. But you definitely are affected by *pressure* altitude!

Go jogging at -40 and feel the burn of that ALWAYS 98F air in your lungs.

OK.

I did my PPL in Tiger. Love the plane.

Do you find yourself jogging much while PIC in a -40 cockpit?
If so, you need to make better life choices. And yes, where the gas exchange takes place, in the alveoli, it’s always 98… that’s your trachea that are burning, not the alveoli…
