I've looked in past posts... and I came up with nothing for my question, but if I missed the answer, I am truly sorry.

What purpose do those small fins serve on the cowlings of the jet engines?

There's also a great link at the the bottom of the box you type in that gives a quick lesson in HTML. It tells you how to do bold, add links, smiles, etc. I still refer to it from time to time.

BTW, welcome to the fourm!
