Safety Information Exchange
Safety Information Exchange (SIE) is the process of making safety information collected by various organisations available to others for the purpose of promoting safety and reducing accident rates.
SIE was promoted in the 1990s by British Airways (BA), as an extension to their safety information management system, BASIS (British Airways Safety Information System). Aircraft operators using BASIS to maintain records of safety occurrences made their databases available to BA, who disidentified the reports and made them available to contributing operators.
The operation of BA's SIE was taken over by IATA, who also commenced analysis of the combined database on behalf of participants. The system has been renamed IATA STEADES (Safety Trend Evaluation, Analysis & Data Exchange System).
The greatest challenge to the succesful operation of a SIE is standardisation of reporting standards between operators. The differing safety cultures existing among national authorities and among operators within the same country is perhaps the most significant factor in this task.
