Abstract: A scheme of controlling data on a training system of cockpit instruments is presented to meet the need of education and teaching for colleges. A training system of cockpit instruments is established based on this scheme. The system consists of three parts: dashboard, aircraft instruments and operate-controlling subsystem. It has been completed. The advantages such as high reliability, easily operating and low cost make this system have a broad market prospect.

Abstract: Traditional mechanical calculations are more often used in the strength check of the amusement facility nowadays. However, there exit some disadvantages in this way, such as the long cycle cost, the heavy workload, and particularly the inability in case of more intricately forced parts. This paper illustrates the idea of using finite element analysis (ANSYS) software to check the strength of Ferris Wheel amusement machine rotating cockpit, analyzes the loads and stresses of the cockpit frame under extreme work conditions, and comes to a reasonable conclusion. And the strength check of intricately forced workpiece of amusement machines are explored as well.

Abstract: Objective To study expert and novice eye movement pattern during simulated landing flight for providing references to evaluate flight performance and training of pilots. Methods The subjects were divided in to two group s of expert and novice according to their flight simulation experience. Eye movement data were recorded when they were performing landing task. Comparison of expert and novice flight performance data and eye movement data was made. Results It was found that the differences between expert and novice lay not only in flight performance but also in eye movement pattern. Performance of expert was better than novice. Expert had shorter fixation time, more fixation points, faster scan velocity, greater scan frequency and wider scan area than novice. It was also found that eye movement pattern of expert bring lower mental workload than novice. Conclusion Flight performance is related to eye movement pattern. Effective eye movement pattern is related to good flight performance. The analysis of eye movement indices can evaluate pilots’ flight performance and provide reference for flight training.

Abstract: The voice interaction in cockpit mainly includes speech recognition, enhancement and synthesis. This interaction transfers the speech information to the corresponding orders to make machines in cockpit work unmistaken, also feedback the execution results to users by speech output devices or some other ways. The speech enhancement technology is studied in this paper, aiming at the Voice Interactive. We propose an improved spectral subtraction (SS) algorithm based on auditory masking effect, by using two steps SS. The simulated results based on the segment SNR compared to the traditional SS show the effectiveness and superiority of the improved algorithm.
