AAIB investigation to Airbus A319, OE-LQE
Loadsheet and takeoff-performance calculation error, London Gatwick Airport, 30 September 2018.
Summary:
The flight crew made an undetected error during the transposition of aircraft loading data from a paper form into their loadsheet calculation software application. As a result, the calculated aircraft all-up-weight (AUW) was 1,962 kg lighter than the actual aircraft weight. This incorrect AUW was used as the basis for takeoff performance calculations. The aircraft took off without difficulty and the flight crew reported the incident upon arrival at their destination. As a result, the airline conducted its own safety investigation into the circumstances and planned to review the way it used its Electronic Flight Bags.
