What are fairings used for on an aircraft?

Fairings are designed to provide aerodynamic smoothness on an aircraft. Their primary function is to streamline the airflow over various structures, such as landing gear, antennas, and other protrusions. This smoothing effect reduces drag, which can enhance overall aircraft performance by improving fuel efficiency and increasing speed. By minimizing turbulence and airflow disruption around these components, fairings help ensure that the aircraft can maintain better stability and control during flight. Consequently, their role in optimizing the aerodynamics of an aircraft is vital for efficient operation and performance.
