On 5 February 2012, a SriLankan Airlines Airbus A340-300 started its takeoff from an intermediate point on the runway for which no regulated takeoff weight information was available on board the aircraft and was observed by ATC and others to become airborne much nearer to the end of the runway than usual. The subsequent investigation found that the flight crew had relied on data for a different runway which did not consider obstacles relevant to the runway used and determined that the regulatory position in respect of this was deficient, leading to corresponding safety recommendations being made
