Risk Assessment for Flight in Uncontrolled Airspace Under Visual Flight Rules

Abstract

Abstract The paper attempts to assess the risk in the area of analysis which is the flight of general aviation (GA) aircraft carried out under Visual Flights Rules in the uncontrolled airspace. The flight, selected for further analysis, is a typical air operation performed in GA. The risk assessment was carried out in accordance with the risk management algorithm. The identification of hazard sources was made using a checklist of 123 questions about their occurrence. On this base a list of 37 threats identified in the presented area of analysis was obtained. The risk assessment was carried out by the MICE-RISK method. Among the defined threats, 16 threats fall into the accepted category, 15 threats are characterized by the tolerated category, and for 6 threats the category is defined as unaccepted. A dealing with risk methods were proposed. The re-evaluation indicated that the number of threats in particular categories are: 27, 6 and 6.
