In the following picture on an MD-11, on the flap handle, there is a portion of it labeled "Dial-A-Flap," and there is what looks to be a corresponding dial-a-flap handle next to the flap handle. Anyone know what "Dial-A-Flap" is?

The "Dial-a-flap" system is a simple mechanism which moves the flap lever detent between 10° and 28° by turning the wheel. Afterwards you set the flap lever into the selected position. This allows for almost unlimited flap extensions in the take-off range depending on aircraft weight and runway conditions.
Don´t try to move the flap lever by turning the wheel, because you might break the mechanism.
The index with the dial-a-flap inscription shows the position of the detent in the center pedestal. Landing setting is normally 15°.

My small exposure to it: The performance tables for any given runway might have one page for Flaps 15, with allowable takeoff weights at given temperatures and another at "Optimum Flap" which would give the MGTOW at temperature and the flap setting to be used.
Similar for the database for computer generated takeoff data. Any current MD-80 pilots confirm that?
