I visited last Saturday. The parking area/apron is not available so we parked in the apron pull in off the main taxiway. The rest of the airfield on the terminal side is still a building site so I doubt very much if they would let you leave an aircraft unattended at the moment. The ILS and NDB are both U/S at present, although the NDB is radiating. Its all worth visiting to see a new major airport in its infancy.
