A Flight Test Engineer is a professional who specializes in testing aircraft and spacecraft to ensure they meet safety and performance standards. They work closely with design teams to develop test plans, analyze data, and troubleshoot any issues that arise during flight tests. Their role is crucial in validating that new technologies and systems function as intended before they are used in commercial or military applications. These engineers often collaborate with pilots and other technical staff to conduct test flights. They gather and interpret data from various instruments, ensuring that all aspects of the flight are monitored. Their findings help improve aircraft design and contribute to the overall safety of aviation.
