Research on Comprehensive Evaluation Method of Airport Runway Operational Effectiveness

In order to assess whether the runway can meet safe, reliable and efficient objectives, a comprehensive evaluation indicator system needs to be established for evaluation. Firstly, the runway operation system is established, and the evaluation indicators of runway performance are divided into five aspects: personnel factors, support facility, mission demand, operating environment and management factors and then establish a comprehensive evaluation index system. Secondly, the TOPSIS evaluation model of game theory combination weighting is established, game theory is used to optimize the weights of the weights obtained by AHP and CRITIC, and the ideal solution (TOPSIS) is used to comprehensively evaluate the runway performance. Finally, the model was used to evaluate the runway performance levels of the three airports, and the three evaluation methods were compared. The results show that the results of the runway performance evaluation using the model are in line with the actual operation of the airport. The method is simple and the results are scientific and objective, and it have good versatility.

TECHNICAL EVALUATION OF A RUNWAY USING THE DEFLECTION METHOD

An aircraft imposes a heavy load on a runway during landing, resulting in deflection of the runway pavement. Therefore, runway performance is influenced by potential deflection levels. Estimating deflection at touch-down point is a challenging task, however. Generally, the applied load depends on the weight and vertical velocity of the aircraft before hitting the touchdown point. Similarly, performance of runway pavement is influenced by many factors such as number of landings, load factor, soil characteristics, etc. This study discusses landing practices, imposed load analysis, and runway pavement evaluation. The study is based on the idealisation of runway characteristics using mechanical elements, and it suggests that the mechanical modelling approach can be applied to estimate runway deflection. As a result, the analytically predicted deflection findings instead of the semi-empirical practices currently followed by various states of the International Civil Aviation Organisation (hereinafter – ICAO) can be used to carry out technical evaluation of a runway pavement.

Modelling Attentional Effects with Head-up Displays

Previous research (McCann, Foyle, & Johnston, 1993) has shown that in a simulated approach to a runway, performance of a choice reaction time task is faster when all relevant information is available on the HUD or in the world, compared to when information has to be acquired from both domains. The present experiment tested two attentional models of these results: attention switching and attention sharing. Removing differential motion cues from the display, so that both the HUD and the world were motionless, attenuated the domain effect. The attenuated difference reflected both slower responses on within-domain trials and faster responses on between-domain trials. We conclude that performance with Head-Up Displays is affected by both attention switching and the degree to which attention is shared between domains.
