Confidential Reporting

Confidential reporting is a well-established safety procedure especially in aviation, one of the first being ASRS (Aviation Safety Reporting System) developed by NASA in 1976 for the Federal Aviation Authority in the USA and as a result of its success, similar schemes have been developed in a number of other countries. In the UK, this is CHIRP (Confidential Reporting Programme for Aviation and Maritime) and in Australia it is REPCON (Aviation Confidential Reporting Scheme). These along with similar systems in other countries are coordinated by ICASS (International Confidential Aviation Safety Systems) that promotes confidential reporting systems as an effective method of enhancing flight safety in commercial air transport and general aviation operations.

CROSS is the first confidential reporting system to deal with structures and CROSS-US is a development aimed at promoting structural safety in the United States.
