EC-HLA was bought second hand by Airbus Defence & Space (EADS by then) after being operated by spanish carrier Air Plus Comet to become the main flying testbed for the A330 MRTT programme. Amongst the modifications to the airframe the most important one is the A330 MRTT Aerial Refuelling Boom System, or ARBS fitted in the back of the aircraft, as well as the control station in the inside.
This livery have been created using the official painkit provided by Inibuilds. Normals have been adjusted to match the livery, as well as decals. Registration and SELCAL placards also match the real airframe. PW engines and PA sounds come in spanish by default. Make sure to select the PAX version, as in the end EC-HLA is not an A310MRTT, but a modified pax airframe.
