Airbus offer a “crippled” version of the A330 for short range use. It’s exactly the same as other A330s but for the lower price and different performance manuals. It will do exactly what any other A330 will do but isn’t legal at the normal weights because of the paperwork.
It can be upgraded at any time simply by paying for new manuals. This way Airbus can offer a lower price for specific needs without discounting normal aircraft.
