How do we fill the head tanks for the CPP system?

Filling the head tanks for the Constant Pitch Propeller (CPP) system is a critical operation, and the most effective method involves turning on the P3 Pump. This pump is specifically designed to move fluid into the head tanks effectively and efficiently, ensuring that the system is ready for operation.

The P3 Pump operates under controlled conditions, which is crucial for maintaining the integrity of the system and ensuring that the head tanks reach the required operating level quickly and uniformly. This automated process minimizes the risk of operator error that could occur with manual filling methods, and it ensures that fluid is supplied at the necessary pressure and volume.

While the other options are associated with the filling process, they do not represent the primary method used to achieve the desired result of filling the head tanks. Simply opening a valve might allow fluid to flow, but without the pump’s action, the process would be inefficient. Checking the pressure gauge is essential during operations to monitor system performance but does not directly contribute to filling the tanks. Manual filling can introduce inconsistencies and potential contamination, making it less desirable than using the dedicated pumping system.
