Is it possible to fly without a certain number of static dischargers installed on the aircraft?

Static dischargers play a crucial role in the safe operation of an aircraft, particularly in dissipating static electricity that can build up during flight. This accumulation can lead to interference with navigational and communication systems, which is why static dischargers are generally installed on aircraft.

The correct answer highlights that while the installation of a specific number of static dischargers is recommended for optimal safety and performance, it may not be strictly mandatory under all conditions. Regulatory bodies often provide guidelines that can include allowances or exemptions based on factors such as the type of aircraft, its operational environment, and maintenance conditions. For example, an aircraft might still be permitted to fly if it has alternative methods to properly manage static electricity, or if it operates in conditions where the risk of static build-up is minimal.

In contrast, the other options imply a more absolute stance on the necessity of static dischargers, which does not reflect the flexible nature of aviation regulations that consider operational contexts and safety assessments. Therefore, acknowledging the permissibility to operate under certain conditions recognizes the nuanced approach taken by aviation authorities when addressing safety and operational requirements.
