Purpose -The main purpose of this study is to introduce the pilots' load model and developed concept of load measuring system for operator load management. Design/methodology/approach -In future aeronautical system, the role of operators (pilots and air traffic controllers [ATCOs]) will be in transition from active controlling to passive monitoring. Therefore, the operators' load (task, information, work and mental) model was developed. There were developed measuring systems integrating into the pilot and ATCOs working environment eye tracking system outside measuring equipment. Operator load management was created by using the measurement. Findings -In future system depending on time and automation level, the role of information and mental load will be increased. In flight simulator practice, developed load management method serves as a good tool for improving the quality of pilot training. According to the test results, the load monitoring and management system increase the safety of operators' action in an emergency situation.Research limitations/implications -The developed method were tested in two flight simulators (one developed for scientific investigation and other one applied for pilot training) and ATM management laboratory. Practical implications -By deployment of the develop load monitoring and management system, the safety of aircraft flights and air transport management will be increased, especially in an emergency situation. Social implications -People and society's acceptance of future highly automated system will be increased. Originality value -The analysis focuses on the following: developing operator's load model as improved situation awareness model of Endsley, developing monitoring system integrated into operator's working environment, creating load management system.
NextGen, SESAR, and other international projects intend to develop the coming air traffic management (ATM) environment to cope with the present problems, including e.g. capacity, efficiency, safety, and environmental impact. These projects also introduce considerable changes in the role of air traffic controllers (ATCOs), and shift some of the present tasks from ground to on-board (pilots) and diversify automation. Due to the consequential effects of these developments, (i) the models describing the present operational circumstances, (ii) the working conditions, and (iii) the working environment (e.g. human-machine interactions, task-work and mental loads, cognitive aspects, situation awareness, decision support) must be reconsidered and adapted to the future role of operators. This paper aims to describe a new approach to model the ATCOs' working processes, and also introduces a new concept for the ATCOs' future working environment. The developed model covers the situation awareness and decision making processes, including the subjective aspects of the ATCOs decision making based on their workload, mental condition, knowledge, or practice. The proposed new working environment contains special information displays, the decision support system and the ATCOs workload and mental condition measurement / monitoring system, based on objective, on-line, continuous, and nonintrusive measurement techniques. Some of the core systems developed in collaboration with HungaroControl were exhibited at the World ATM congress in 2014 and 2015.
The large, EU Supported ESPOSA (Efficient Systems and propulsion for Small Aircraft) project has developed new small gas turbines for small aircraft. One of the important tasks was the engine - airframe aero-thermal radiation integration that included task of minimizing the infrared radiation of the small aircraft, too. This paper discusses the factors influencing on the aircraft infrared radiation, its possible simulation and measurements and introduces the results of small aircraft infrared radiation measurements. The temperature of aircraft hot parts heated by engines were determined for validation of methodology developed and applied to engine - aircraft thermal integration.
The International Civil Aviation Organization is estimated that the number of domestic and international passengers will be expected to reach six billion by 2030. This exponential growth in air transport has resulted in a wide range of adverse effects such as environmental impacts. The purpose of this research is to develop new air traffic management, and operator (pilots, air traffic controllers) load measuring systems in order to save fuel, and flight time, thereby reducing environmental impact, carbon emission, greenhouse gas generation, noise pollution, and operating cost. This paper deals with: (i) dynamic sectorization and airspace configuration (ii) introduction of the highly dynamic approach and landing procedures, (iii) dilemmas of human in sustainability (related to the individuals, the society, the non-governmental organizations, and the managers), and (iv) development of dedicated non-intrusive operator supporting systems based on eye-tracking, heart rate, and electrodermal activity. Due to the consequent effects of these developments, the dynamic sectorization and air space configuration may eliminate the task overload and reduce the actual operator load by 30–40%. With the developed concept of dynamic approach and landing procedures, aircraft will be able to follow better trajectories to avoid residential areas around airports to (i) reduce ground noise, and emission, (ii) avoid encounters severe weather and prevent incidents and accidents, and (iii) decrease landing distance up to 56% in compared to the “published transition route”.
