A Test Pilot is a highly skilled aviator responsible for flying and evaluating new aircraft or modifications to existing ones. Their primary role is to assess the performance, safety, and handling characteristics of these aircraft during various flight conditions. Test pilots often work closely with engineers and designers to provide feedback that can lead to improvements in aircraft design. These professionals typically have extensive flight experience and specialized training in aerodynamics and engineering. They may test military aircraft, commercial airliners, or experimental vehicles, contributing to advancements in aviation technology. Notable test pilots include Chuck Yeager, who famously broke the sound barrier, and Neil Armstrong, who tested various aircraft before becoming the first person to walk on the moon.
