Aircraft Drain-Vent

Aircraft drain-vents are small openings or valves located on the exterior of an aircraft that allow for the drainage of fluids, such as water or fuel, from various systems or compartments. These drain-vents are designed to prevent the accumulation of fluids that may have entered the aircraft during flight or while on the ground.

The drain-vents are typically positioned at low points in the aircraft's structure, such as the bottom of fuel tanks or the lower fuselage, to ensure that any collected fluids can be easily drained away. They are often equipped with filters or screens to prevent debris or foreign objects from entering the drainage system.

In addition to draining fluids, aircraft drain-vents also serve as ventilation outlets for certain systems, such as the fuel tank venting system. This helps to maintain proper pressure and prevent the buildup of potentially hazardous gases.

Overall, aircraft drain-vents play a crucial role in maintaining the safety and functionality of an aircraft by ensuring the proper drainage and ventilation of fluids and gases.
