What to do
Operators should conduct dedicated safety risk analyses to evaluate current procedures related to take-off parameter calculations and data entry. They are encouraged to implement or enhance FDM programs to identify precursor events and improve error detection. Flight crews should receive targeted training on common errors, verification methods, and appropriate responses to inadequate take-off performance. No specific compliance deadlines are stated.
Summary
EASA Safety Information Bulletin 2016-02R1 is an updated operations bulletin addressing the risks associated with the use of erroneous parameters during aircraft take-off. It highlights common errors in entering take-off mass, performance data, and speeds into Electronic Flight Bags (EFB) and Flight Management Systems (FMS), which can affect any aircraft type. The bulletin emphasizes the importance of accurate data entry to prevent incidents such as tail strikes, runway overruns, and loss of aircraft.
What changed
This revision updates the original EASA SIB 2016-02 by incorporating the latest developments in Flight Data Monitoring (FDM) programs and refining the description and recommendations sections. It introduces enhanced guidance on using FDM to detect and analyze take-off performance errors and expands on mitigation strategies including crew training and automated system checks.
Why it matters
Accurate take-off performance data is critical for flight safety, and errors can lead to serious incidents or accidents. Aviation professionals, including operators and flight crews, must understand the human factors contributing to these errors and implement effective monitoring and training to reduce risks. This bulletin supports safety management by promoting proactive detection and mitigation of erroneous data entries.
