A particularly investigation is carried out to the observibility of in-flight alignment using numerical simulation when the aircraft performs four kinds of basic maneuvre, namely linear acceleration, yawing, pitching and rolling. The thesis summarizes the two kinds of maneuvre. Simulation results show that the precision of transform alignment reach 5 minutes in 10 seconds if the aircraft performs two well-defined maneuvres.

首先本文采用数值分析的方法研究了直线运动、航向角运动、俯仰角运动和横滚角运动对传递对准系统可观性的影响规律；再结合飞机的实际运动，给出了空空导弹传递对准时的飞机飞行轨迹；"蛇形"飞行轨迹和摇摆运动飞行轨迹，仿真结果表明：按这两条飞行轨迹机动，在10s内传递对准精度可达到5′以下。

Results Class I allergic rhinitis (without symptoms of secondary barotraumas in flight), class II allergic rhinitis (with symptoms of secondary barotraumas in flight), perenial allergic rhinitis, and pollinosis were diagnosed in 30, 23, 28, and 25 pilots, respectively. Forty-four pilots could continue their flying and 9 pilots were permanently grounded.

In a letter from the Secretary of War to the Director, Bureau of Budget, dated 9 March 1942, the Secretary submitted a proposed executive order establishing the Air Medal for award to any person who, while serving in any capacity of the Army of the United States, distinguishes himself by meritorious achievement while participating in an aerial flight The Secretary of War, in his request, stated The Distinguished Flying Cross is available only for heroism or extraordinary achievement while participating in aerial flight…It is desired not to cheapen the Distinguished Flying Cross by awarding it for achievement not bordering on the heroic.

&在由陆军部长致函处长，预算局，日期为1942年3月9日，秘书长提交了一份建议的行政命令，建立授予任何人的空中奖章谁，而服务在任何联合国军的能力国家，区分自己的优良成绩，而在空中飞行的陆军部长，在他的要求表示，&杰出飞行十字勋章的可用于英雄主义或不寻常的成就不仅参加，而在空中飞行参与。。。这是预期的不贬低杰出飞行十字勋章的授予的成就不是接壤的英雄。
