Aircraft would generally be monitored to the lubricating oil amount of electromotor, such as every default first time period or at each not
Same mission phase obtains the actual lubricating oil amount of described electromotor.
Under normal circumstances, the reality of described electromotor can be obtained by measuring the lubricating oil amount in described lubricating oil storage container
Border lubricating oil amount.This is because, the lubricating oil of electromotor is typically stored in lubricating oil storage container, when supplementing lubricating oil, by lubricating oil
Add in described lubricating oil storage container.
In being embodied as, described electromotor can be both aircraft engine or other needs using lubricating oil
