What is a flight log used for in rocketry?

A flight log is fundamentally important in rocketry as it serves as a comprehensive record of all details regarding a rocket's launch, including performance data. This log captures key information such as the times of ignition and apogee, altitude achieved, recovery method employed, and any anomalies observed during the flight. This data is crucial for analyzing the rocket’s performance and behavior during launches, which can inform future designs and improvements.

In addition, the flight log can contribute to a broader understanding of trends in data that can enhance safety and reliability in subsequent launches. Having a meticulously maintained flight log can be invaluable for both hobbyists and professionals in the field of rocketry, aiding in the process of troubleshooting and enhancing rocket designs based on empirical evidence.
