PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

What is the minimum wing tank fuel level required for the transfer ejector valve to open?

1. Below 90%

2. Below 94%

3. Below 92%

4. Below 91%

The correct answer is: Below 94%

The minimum wing tank fuel level required for the transfer ejector valve to open is indeed below 94%. The transfer ejector valve is a critical component that helps ensure proper fuel management within the aircraft's tank system. When the fuel level in the wing tanks drops, the valve is designed to open below this 94% threshold to allow for fuel transfer and balance, thus maintaining the airplane's center of gravity and ensuring safe flight operations. Understanding the operational mechanics of the transfer ejector valve and the specific fuel levels that trigger its operation is essential for managing fuel effectively during flight. This knowledge is crucial for flight crews to maintain optimal performance and safety standards.
