新歼HUD画面练习软件的效度研究

通过平视显示器（HUD）使用经验不同的30名飞行员应用HUD画面练习软件成绩的比较,检验软件的效度。结果表明：三组被试第一次成绩比较显示,有新歼HUD使用经验组与其它两组比较有统计学意义,存在显著性差异（F=20.44,21.50,P〈0.05）。但无HUD使用经验的两组比较无明显差异（F=1.06,P〉0.05）。6次比较的重复测量结果显示,有新歼HUD使用经验组与无HUD使用经验普通练习强度组有统计学意义,存在显著性差异（F=13.32,P〈0.05）。无HUD使用经验加大练习强度组与有HUD使用经验组和无HUD使用经验普通练习强度组比较无明显差异（F=7.24,6.08,P〉0.05）。对三组被试自身对照的重复测量结果进行分析,各组被试的第一次练习成绩与第五、六次成绩均存在明显差异（F=-12.71,-13.39,-34.07,-35.13,-26.04,-27.83,P〈0.01）。结论：新歼HUD画面练习软件对于不同经验背景的被试的区分效度较好,能在一定程度上提高被试HUD画面的练习成绩,有助于提升飞行员HUD认读的能力。

A Validity Study of New Fighter HUD Screen Practice Software

To evaluate the validity of New Fighter HUD screen practice software using 30 pilots with different experience. Results: Significant difference was found between the experienced group and the other two groups after first time of training( F = 20.44,21.50 ,P <0.05). And no significant difference was found between the groups with different training intensity(F = 1.06, P>0.05). Results of 6 times of training showed that there was significant difference between experienced group and none - experience group with general intensity(F = 13. 32,P <0. 05). Results of subjects in none - experience group with great intensity had no significant difference with the results of the other two groups(F = 7.24,6.08, P>0. 05). And there were significant differences between the results of first time training and the fifth and sixty time of training, comparing the results of every time of training using ANOVA of Repeated Measures (F = -12.71、-13.39、-34.07、-35.13、-26.04 and -27. 83,P <0. 01). Conclusion; New Fighter HUD screen practice software has good discriminating validity, it can increase the results of using HUD screen to some degree, and improve the pilots' capability to recognize and read the HUD.
