Abstract:

The safety analysis of wheel brake system in the aircraft landing process is regarded as a system control problem in this paper. Instead of the accident model based on failure probability, we use the systems-theoretic accident model and process (STAMP) accident model based on systems thinking to construct the STAMP control interaction model and the systems-theoretic process analysis (STPA) feedback control loop of wheel brake system. Furthermore, the unsafe control actions in the aircraft landing process are identified by the context of running system, and the causes of unsafe control actions are analyzed. Finally, the unsafe control actions of wheel brake system in the aircraft landing process are studied by simulation. It is shown that the STAMP/STPA method is effective and the simulation method is feasible with respect to safety analysis.

Key words: wheel brake system, STAMP, STPA, unsafe control, simulation analysis
