A Novel Evaluation Method of Multi-channel Information Push Efficiency in Aviation Flight

Based on information push, pilot’s information recognition is of great significance for air combat situation awareness. In modern aviation system, information push is more complicated and generally multi-channel. Under this background, more and more research are made on the efficiency improvement of information push. In this paper, an instigate about multi-channel information push efficiency is conducted. A push efficiency evaluation model is studied based on the combination of subjective and objective method. Then, experiment is designed and implemented to make exploration about the potential impact factors of push efficiency, including noise level, screen number and push method, and to establish and verify the proposed evaluation model. Based on the experiment and data analysis, an evaluation model combining of attention allocation model, situation awareness model and cognitive load model is built and validated. A radar chart is adopted to demonstrate the evaluation result of information push efficiency of different systems. As a conclusion, voice information push is of higher efficiency comparing with text information push and voice-text information push.
