Abstract

ASAS (Airborne Separation Assurance System) is an aircraft system based on airborne surveillance that provides assistance to the flight crew, supporting the separation of their aircraft from other aircraft. This paper describes the process that was used to analyse possible human factors and safety issues affecting an air traffic management (ATM) procedure associated with ASAS. The paper provides some illustrative findings and explains the benefits and difficulties with the method used. A hierarchical task analysis (HTA) and human error analysis (HEA) were undertaken for ASAS separation. These analyses were used to develop eight safety scenarios for a five day real-time simulation. By simulating hazardous events in real-time simulations, it was possible to observe and discuss with controllers how hazards are detected, and to determine possible means of mitigation.
