What is the recommended action if the red oil pressure warning light illuminates?

When the red oil pressure warning light illuminates, the recommended action is to adjust the Power Control Lever (PCL) to the minimum necessary to intercept the Engine Low Power (ELP) profile. This choice prioritizes maintaining control of the aircraft by ensuring that as little power as necessary is used while addressing a potentially critical situation concerning oil pressure.

Reducing the power allows the pilot to begin the process of safely managing the engine's performance while minimizing the risk of engine failure. Continuing normal operations is not advisable in this scenario, as it ignores the significant warning indicated by the red light, which suggests an urgent issue with oil pressure that could lead to engine damage or failure.

Opting for maximum performance settings, such as setting the PCL to maximum for climb, is not appropriate in this situation, as it could exacerbate any underlying issues with the engine. Similarly, shutting down the engine immediately is a drastic measure that may not be warranted unless further indications suggest a need for immediate engine failure response. Therefore, adjusting the PCL to the minimum necessary ensures a cautious approach to managing the situation while preparing for potential engine failure.
