Why is it important to have an adequate vent in the aircraft pesticide tank?

Having an adequate vent in the aircraft pesticide tank is crucial for preventing a vacuum from altering the normal flow of liquid. When pesticides are being drawn from the tank through the application system, a vacuum can form if there is insufficient air to replace the liquid being removed. This vacuum can restrict the flow of the pesticide, leading to inconsistent application rates and potentially causing the system to malfunction.

By ensuring that there is adequate ventilation, air can enter the tank as liquid is expelled, allowing for a smooth and uninterrupted flow of the pesticide. This not only promotes efficient operation but also ensures that the application is uniform, which is vital for effective pest management and reducing product waste. Proper venting safeguards both the performance of the application equipment and the efficacy of the pesticide being used.
