Final answer:
The APU may be started and operated even if the LOW OIL LEVEL ECAM advisory is displayed, but it should be closely monitored. Starting and operating the APU with low oil levels can lead to further damage and possible failure. The LOW OIL LEVEL ECAM advisory alerts the crew to a potential issue with the oil level in the APU.
Step-by-step explanation:
The APU may be started and operated even if the LOW OIL LEVEL ECAM advisory is displayed, but it should be closely monitored. The LOW OIL LEVEL ECAM advisory means that the oil level in the APU is below the normal range, indicating a potential issue with lubrication or fuel flow.
Starting and operating the APU with a low oil level can lead to further damage and possible failure. It is important to address and rectify the low oil level condition as soon as possible to ensure proper functioning of the APU.
The APU (Auxiliary Power Unit) is a device in aircraft that provides on-board power while on the ground or in flight. It is important for the APU to have proper oil levels to ensure its smooth operation, and the LOW OIL LEVEL ECAM advisory alerts the crew to a potential issue with the oil level.
