Airbus A300-600

The A300-600 is the B4 rebuilt around the A310: the same wing and the same take-off weight, but the A310's rear fuselage — which puts two more seat rows in the same length — and its two-crew flight deck, so the flight engineer's station went. Certified in March 1984. It seats 274 in a single class and is approved for 361. Cruise speed, range, ceiling and climb rate are EUROCONTROL's figures for the A306 type code rather than a certificate's: a type certificate states limits and weights, not cruise performance, and the source does not distinguish sub-variants.
