Airbus A340-642, G-VYOU
During pre-flight preparations, the estimated landing weight was used to calculate takeoff performance rather than the takeoff weight. The error was not detected and the aircraft took off using values for VR and V2 that were significantly lower than those required for the actual takeoff weight. The aircraft was slow to rotate and initial climb performance was degraded but the aircraft continued to destination without further incident.
