Mississippi Aerial Application (Category 11) Practice Test

The primary purpose of baffles inside a liquid spray tank is to reduce sloshing of the liquid during flight. When an aircraft maneuvers, the liquid inside the tank can move rapidly from side to side, which can affect the aircraft's balance and stability. Baffles are designed to disrupt this movement, thereby providing a more stable environment for the liquid. This stability can enhance the accuracy of the application, as a more consistent flow rate can be maintained with less fluctuation in the liquid volume.

While other functions, such as mixing materials or addressing issues like foaming and pressure changes, are important aspects of a well-functioning spray system, they are not the primary role of baffles in the context of aerial application. Baffles are specifically engineered to control liquid motion under the dynamic conditions present during flight, making them essential for safe and effective aerial spraying operations.
