Question: 1 / 400

How much oil is required for the APU?

56 fl oz

87 fl oz

The correct amount of oil required for the Auxiliary Power Unit (APU) is 87 fluid ounces. This specification is crucial because maintaining the correct oil level ensures that the APU functions efficiently and reliably. The oil lubricates the moving parts of the APU, minimizes friction, and helps to dissipate heat generated during operation. Insufficient oil can lead to increased wear and potential failure of the unit, while excess oil can also cause operational issues. It is important for personnel involved in aviation maintenance to be familiar with these specifications to ensure the aircraft's systems operate within their designed parameters.
