Abstract : The Defence and Civil Institute of Environmental Medicine (DCIEM) and Air Transport Group (ATG) were tasked to conduct a joint study of human factors concerning the CC-130 Hercules aircraft. The aim of the study was to establish human factors issues relevant to air accidents, and to recommend preventative measures. The study was organized around two working groups: the Crew Behaviour Assessment Group (CBAG) and the Flight Performance Assessment Group (FPAG). The CBAG developed a method of measuring the ability of the crew to coordinate their activities efficiently and manage their workload. The FPAG developed a method of measuring the accuracy and consistency of simulator flight along an aircraft flight path. Data to support the development of both methods were obtained from a simulator study of 23 ATG crews. The results defined the characteristics of high proficiency Aircraft Commanders (ACs) and those of less proficient ACs. Less proficient ACs seemed to focus primarily upon systems-related, procedural cross-checking and rechecking of information, and had more open-loop communication which supports the contention that these individuals were becoming task overloaded. The results suggest that a proportion of ATG crews are adversely overloaded by the occurrence of unexpected flight events and certain system failures. Since behaviour can be influenced by training, this study recommends a review and modification of the current CC-130 training program, including Aircrew Coordination Training (ACT).
