Time Simulation

The study tested guidelines for the use of microprocessors in training spatial skills for air traffic control. The central issue was the use of time-compressed simulation to aid the development of skill in identifying turn points and rollout headings for aircraft. Two groups of subjects were used. One group trained with a real-time simulation of the task, while the second group trained with a time-compressed version of the task running about 20 times as fast as real-time trials. Both groups were then tested in real-time trials. The results indicate that time compresssion can be a useful technique for increasing the efficiency of training.

Objective Evidence

Numerous real-time air traffic control simulation studies have been conducted in the United Kingdom; this paper summarises what has been learned from them. Realistic assessments of the validity of real-time simulation as a method of solving air traffic control problems are now possible in the light of experience, and its future use can be planned in accordance with its known limitations. Real-time simulation cannot answer every kind of question with equal validity, and its relevance for assessing capacity, workload or stress is dubious. Measures in simulation may be chosen primarily for their practical convenience and because they can provide answers expressed in system concepts, but the technique can be used to show discrepancies between subjective and objective evidence, and to suggest why they have arisen. Real-time simulation is both indispensable and over-used in air traffic control.

Operator Fatigue

This study examined the utility of continuous operator state monitoring in predicting air traffic control officer (ATCO) workload and fatigue. Participants (N=8) were observed in live operational air traffic control environments for 60-minute periods. ATCO state was assessed using a real-time, computer vision-based system which tracked operator gaze and pupil diameter. Workload and fatigue were also assessed via the adapted Bedford Workload Scale and Samn-Perelli Fatigue Scale, respectively. Standard deviation of gaze was a significant predictor of both max and mean workload, showing a strong negative relationship with both subjective measures. Pupil diameter showed a significant positive relationship with operator fatigue. Our findings demonstrate the utility of continuous ocular metrics of workload and fatigue in operational environments.

Time Simulation

Purpose Unmanned aerial vehicles (UAVs) are more affected by adverse wind conditions in especially landing. Therefore, they need to change the runway in use. In case of this change, to eliminate the uncertain maneuvers, there is a need for a special prescribed track. The purpose of this study is the construction of a prescribed track at a single runway to provide a facility to change the runway in use. Design/methodology/approach Two forms of prescribed tracks, as standard and alternate, were constructed for UAVs by taking into consideration the key parameters to design flight procedures. Both tracks were assessed in a real-time simulation method. Moreover, unmanned vehicle simulation was used for a validation process. Findings According to the real-time simulation results, 8.14 NM and 6.64 NM of flight distance and 5.43 min and 4.43 min of flight time for the standard and alternate prescribed tracks were found, respectively. The obtained results were in favor of the alternate prescribed track. Furthermore, the prescribed track was assessed and validated in both air traffic control and UAV simulations. The feedback of pilots and controllers was very positive for a prescribed track, as it provided them with foresight and time to take care in any situations. Practical implications The prescribed track in this paper may be applied by airspace designers and UAV users to perform safe and efficient landing in adverse wind conditions. Originality/value In this study, a prescribed track was constructed for UAVs. Quantitative results were achieved using a real-time simulation method in terms of flight distance and flight time. Additionally, validation of the prescribed track was achieved by unmanned air vehicle simulation.
