What is the starting oil pressure range for the King Air 350?

The starting oil pressure range for the King Air 350 is critical for ensuring that the engine is properly lubricated during operation. The correct choice indicates that the oil pressure should be between 0 and 200 PSI at start-up. This range is designed to provide sufficient pressure to maintain lubrication within the engine, which is essential for preventing wear and tear on engine components.

When the oil is cold at start-up, it has a higher viscosity, meaning it takes more effort for the pump to circulate it, which can result in lower initial pressure readings. However, as the engine warms up, the oil thins and allows for better flow, raising the oil pressure to the normal operating levels that fall within this specified range.

This specification ensures safe engine operation and helps avoid scenarios where inadequate lubrication could lead to engine damage. Understanding these parameters is fundamental for pilots and maintenance personnel to ensure the longevity and reliability of the aircraft's engine systems.
