The Mitigation Design of Failure Conditions Level System with System Functional Hazard Assessment (SFHA) on Unmanned Aircraft MALE Class (original) (raw)

Scientific Research Journal

Hazard in technological development can occur anywhere, anytime, and caused by various factors. Every technology product has the possibility to failed or error in its operation. This failure can endanger the product itself, its users or the environment around it. The purpose of this research is to design mitigation for failure conditions at the system level in order to minimize and avoid the impact of failure conditions on an unmanned aircraft named PTTA MALE .The method used is descriptive qualitative method including architecture observation, discussion and interviews with experts. Research was also conducted using quantitative methods based on international standard documents (ARP 4761 & STANAG 4671) to improve the analysis of failure conditions. Mitigation design with a System Functional Hazard Assessment (SFHA) is carried out for each system level failure condition. Failure conditions are generally categorized into detected, undetected, announced and unannounced failures. When a failure condition occurs, the pilot can take action according to the best mitigation that has been designed, for example by turning off the automatic power control, or continuing the operation in manual mode. The results of this research can serve as a guide for pilots in operating PTTA MALE.
