Flight testing is a crucial phase in the development of aircraft and spacecraft. It involves evaluating the performance, safety, and reliability of a vehicle in real-world conditions. Engineers and test pilots conduct a series of flights to gather data on various aspects, such as speed, altitude, and maneuverability. During flight tests, specific objectives are set, including assessing how the aircraft responds to different controls and environmental factors. The information collected helps identify any issues that need to be addressed before the vehicle can enter commercial service or be used for its intended purpose.
