关于737NG飞机 APU MAINT灯与LOQ指示的出现时间的疑惑。

737NG手册APU指示章节中有讲到The blue MAINT light on the P5 panel comes on and the LOW message shows on the APU oil quantity page of the CDU when approximately 3.8 quarts (3.6 liters) of oil remains in the APU sump.
意思是说MAINT灯亮的同时CDU上出现低滑油量指示。但在APU控制章节中又讲到
LOW level first shows when there is approximately 365 hours of APU operation at normal oil use rate until the APU does a protective shutdown caused by low oil pressure. At the maximum oil consumption rate, there is approximately 19 hours of APU operation from when LOW first shows until the APU does a low oil pressure protective shutdown.
NOTE: The low oil quantity (LOQ) maintenance light will come on when there is enough oil in the APU for 30-50 hours of operation at the maximum oil consumption rate before the APU will shutdown because of low oil pressure.
大致意思是从低滑油量显示到保护性关断APU以最大滑油消耗量能运行19小时，从MAINT灯亮到保护性关断以最大滑油消耗量能运行30-50小时。这样是不是可以理解为MAINT灯亮是在LOW message出现之前呢？两章的解释似乎有些冲突，哪位大哥能给解释一下？

根据你的“从低滑油量显示到保护性关断APU以最大滑油消耗量能运行19小时，从MAINT灯亮到保护性关断以最大滑油消耗量能运行30-50小时。”可以得出MAINT灯先亮
