Where are static dischargers typically installed on an aircraft?

Static dischargers are critical components designed to safely dissipate static electricity that builds up on an aircraft's surface during flight. The primary installation points for static dischargers are on the wings and tail extremities due to several reasons.

The wings and tail extremities are the areas of the aircraft that experience the most significant airflow and are prone to the accumulation of static charge. As the aircraft moves through the atmosphere, friction can lead to the buildup of static electricity. This static charge can interfere with communication and navigation systems if not properly managed. By placing static dischargers at these locations, static electricity is allowed to discharge harmlessly into the atmosphere, thereby reducing the risk of electrical interference.

Moreover, the design and aerodynamic considerations of the aircraft mean that these extremities are ideal locations for such devices. They are strategically positioned to maximize the effectiveness of static discharge while maintaining the aerodynamic integrity of the aircraft.

In contrast, other locations such as above the cockpit, inside the engine compartment, or underneath the fuselage are not as effective for static discharge purposes due to factors like airflow dynamics, potential interference with critical aircraft systems, and structural design limitations. Therefore, the installation of static dischargers on the wings and tail is the most effective and widely accepted
