A precursor flight is a term used to describe an experimental flight that is meant to pave the way for a future flight or mission. Synonyms for this term might include experimental flight, test flight, trial run, prototype flight, shakedown flight, or proof-of-concept flight. These terms all convey the idea of a flight that is designed to evaluate the feasibility and functionality of a new technology, design or system before it is deployed on a larger scale. In aviation, precursor flights are an essential component of the development process, helping engineers and researchers refine and improve their ideas to ensure safe and successful flights in the future.
