What this relates to:
Incorrect load sheets resulting in wrong aircraft loading or vice versa, errors in take-off weight or balance calculations, or flight parameters. Such mistakes may compromise operational safety.
Example:
An aircraft is fully loaded, but a check of the load sheet reveals improper cargo distribution, making safe flight impossible. The aircraft must be reloaded, leading to significant passenger delays.
Remarks on the 2024 figures:
Reported loading errors increased by 8% in absolute terms compared to the previous year. However, in relation to the number of movements it remained stable at an average of 4 incidents per 10,000 commercial air transport movements. All mentioned cases occurred at Swiss aerodromes and involved commercial operations.
Causes varied but were often linked to incorrect baggage or cargo loading, including dangerous goods, or errors in the loading plan. While most incidents had no significant impact on flight operations, some affected the aircraft’s weight and balance. In a few cases, the centre of gravity shifted beyond safe limits, posing risks such as in-flight control difficulties or tail tipping during ground loading.
Despite the increase in incidents in 2024, less than 6% had a serious impact on flight operations.
