@redtailflightacademy: Why does frost only form on top of airplane wings? 🌨️✈️ The upper surface cools faster, dropping below freezing while the underside stays warmer . . . #AviationFacts #PilotTips #FlightTraining #AviationScience #Meteorology #FrostFormation #AviationEducation #LearnToFly #Aviation101 #PilotLife
Not only that, but when pressure drops (like on top of a wing), the temperature goes down as well. So the airflow on top of the wing is also cooler than the airflow on the bottom of a wing.

I would’ve thought it’s caused by lower pressure at the top of the wing, raising the dewpoint

Isn’t this just aerodynamic cooling?

I get frost under my wings. From the super cold fuel. -74 Capt

Basically radiation fog from the top of the wing.

What if the wing is black?

I’m not sure if that’s a valid hypothesis. Do you have a reference?

Fuel also will keep it warmer than top of the wing

Frost forms all the time on the bottom (and top) of a wing on larger planes. It’s the effect of cold soaked fuel and relatively warmer moist air after landing.

You’re not allowing for the potential temperature difference of the fuel in the wing and the surface of the wing. There are different types of frost. Some can form on the under side of the wing

How’d you start to become an aircraft mechanic and how’d you recommend a 20 year old in GA to start to get where you are I’d like to start if it’s ok to ask and what books, sites and methods you used to learn the material I’d like to start but programs like AIM are expensive
