Steve,

Thanks for the formulas!!!

I remember almost all of that except I'm having a hard time recalling what "e", the Oswald effect factor, is in the Induced drag formula.

I guess Dr. George did OK teaching me in the Gen. Aero class at Parks ; I remember we all would chuckle at the way he would say "slugs" in class .

Thanks for the links too!!! Exactly what I need to look at for a refresher.
