Today's route proving programme involved two short legs on some of Asia's busiest trunk routes, as the A340-600 left Narita this morning for Taipei arriving at lunch time and leaving again in afternoon for a flight back to Hong Kong. The aircraft remains on static display in Hong Kong for the rest of the day before departing tomorrow morning for its first trans-pacific flight. It has covered more than 17,000 km/9,200 nm so far.
