SCSC - The Safety-Critical Systems Club


Seminar on Data Safety

Data can directly cause systems to behave anomalously (e.g. sensor data in the Boeing 737 MAX) or it can cause humans to take inappropriate actions leading to harm. On November 14th in London the SCSC is holding a seminar "Data Safety Evolution". This seminar is an opportunity to hear about the issues data can cause in safety systems and look at new developments in the area. It will be useful for safety engineers and safety managers, across any sector that uses data in a safety context. Full details at:
