Decision making in emergency situation of air navigation system’s operator: low oil pressure.

Abstract

Air navigation system can be considered as a complex system with multiple composite parts or subsystems that constantly interact with each other, e.g.: – Airspace users (AU); – Air navigation service providers (ANSP); – Airports; – Network Manager (NM). Due to growing demand in air transportation, the complexity of the systems and load on it increases constantly. However, at the same time, the requirements for the level of safety, security remains the same. In order to meet the required levels of safety, there is a need for supporting systems that would support operators (e.g. flight crew, air traffic controller, etc.) of air navigation systems in making decision in day-to-day operations. That’s why the decision support systems became widely used in the air navigation systems to support the human operators. They are aimed at helping and supporting decision making processes or human operators in air transportation sphere and allow them to select the best decision in conditions of limited time or uncertainty. The wide introduction of decision support systems in air navigation will contribute to the optimisation of human operator work which will lead to an increase in operational efficiency and safety. One of the components that negatively contribute to the safety of flights are human errors that could lead to emergency situations and later on to incidents or accidents. The emergency situation of low oil pressure is a serious issue for both flight crew and air traffic controller and possess a threat to the flight safety due to its nature. It can lead to serious incidents and accidents and due to the type of the issue it is close to impossible to eliminate it. However, it is possible to provide all necessary means to support decision making of a human operator (e.g. air traffic controller) to ensure that correct and safe decisions are taken by the operator to resolve an emergency situation.
