On 29 March 2018, an augmented Boeing 787-9 crew completed an uneventful takeoff from Tel Aviv on a type conversion line check flight for one of the First Officers in the crew. After getting airborne, the crew found that all performance calculations including that for takeoff had been made on the basis of a Zero Fuel Weight which was 40 tonnes below the actual figure of 169 tonnes. The Investigation found that it was highly probable that automatic reduction in commanded pitch-up when rotation was attempted at too low a speed had prevented an accident during or soon after liftoff.
