Then there is "Variable-Incidence". From the Vought Crusader (F8U), one garnered an opinion of AOI that remains, and I think of it as important to flight line from the cockpit.
On approach to the Carrier, the Cru's wing would elevate its leading edge to allow the Pilot to see the deck ahead, and the wires.
The only other use I think this old term has is its relationship to AoA at cruise, and only to define the inclination of the aisles relative to Trolley creep.
