Philosophy on Safety Risk Management

Predictive thinking, proactive implementation and reactive response.

Comprehensive, effective, feasible and sustainable.

Effective safety management requires the ability to have the right system to collect and analyze the right information at the right time.

FORASFlight Operations Risk Assessment System

• FORAS is a system which designed to capture risk attributes on the areas of crew, aircraft functionality and sector threats, and allow risk mitigation efforts could be deployed before the flight.

Flight Operation Risk• Newly check out Captain and F/O flying together• Fatigued crew with MRT• Non precision approach or ILS out of service• Strong cross wind• Low visibility with rain or snow• Thrust Reverser INOP• RWY is not grooved with percipitation• The complexity of approach procedure & runway configuration• Operating crew never operating into this airport before

Project Background

14

System Introduction• FORAS is a methodology for generating a risk model, which produces

a relative, quantitative measurement of a specific risk exposure in flight operations.– Gather the weather information, crew experience, navigation aids, and

aircraft’s status etc.

• A decision support tool to measure and reduce risk exposure.– A decision aids for risk awareness, not a GO or NO GO decision tool.

• Proactive, predictive approach to aviation safety.– Analyze operational risks and take the actions of relevant risk mitigation

to ensure a safe operation.

Conclusion

• The core elements of Safety Management System is hazard identification & risk management. FORAS is playing a vital & predictive role on Safety Risk Management.

Why we need FORAS?

FORAS Promotion Program• Promote FORAS via a non commercial avenue• Airlines who are interesting to acquire FORAS shall

donate certain amount of fund into FORAS Fund according to its fleet size.

• Set up a FORAS Fund and manage it via a committee of trustees

• The Fund will be utilized to set up FORAS Scholarship, FORAS Award and the future development of FORAS, and other aviation risk management initiatives.

FORAS Promotion Program will be available on Q4 2013.
