AOA = Angle Of Attack
The angle with which the wing contacts the impinging air stream

L/D = Lift to Drag ratio
As AOA goes up, so does lift, but drag goes up too. Knowing what the L/D
curve looks like for a specific airfoil as AOA increases is an important
point in designing an aircraft to meet a stated mission.

Clmax = Maximum coefficient of lift
The AOA where the wings lift is maximum. Usually occurs at an AOA just
before stall.

L E Slats = Leading Edge Slats

AOA, L/D, Clmax and LE slats are what exactly?.... Been out of the
whole sport aviation for some time and just trying to grasp it all over
again..

thanks..
