dunno about the new citation but on the old one the "AOA" was calibrated for clean and full flap. On full flap and gear down you would have the Red / Green / Amber Light repeaters on the glareshield. On clean it shows the best L/D at .55
On the Falcons AOA are used to trigger the stall protection ie extending slats at 17° and retracting the inboards at 19° for example (depending on model of course)
Safe Flight manufacturer of those kits got a lot of info handy if you ask them.
