摘要
一、必要性与可能性随着航空技术装备的发展,自动定向机从第一代电子管电路,第二代晶体管电路,发展到今天的集成电路和全固态数字化微处理电路,体积小、重量轻,准确度、定向精度、可靠性均大大提高,具有人工试验检测系统和自动故障检测储存系统,以及警告旗显示工作正常与否等。但有时对某些错误的定向方位指示。
Making use of the magnetic heading α_h indicated by the magnetic compass on plane and the Longitudinal axis of the plane indicated by the finder of the ground beacon with which the frequency is selected, with the sum of relative bearing β_R of the ground beacon is equal to interrelation among the three to the magnetic bearing M_D of the ground beacon. It can be used to judge the accuracy of the automatic direction finder, which is simple, applicable, convenient and reliable, and advantageous to the disposition of special cases occurred as well as complicated weather conditions encountered in flight, to the guarantee of flight safety and enhancement of maintenance quality.
