What is a common use for a hygrothermometer in aviation?

A hygrothermometer is specifically designed to measure both temperature and humidity levels in the environment. In aviation, maintaining the right conditions in the cockpit or cargo areas is vital for both the comfort of crew and passengers, as well as the integrity of sensitive equipment and materials. By accurately monitoring temperature and humidity, aircraft can ensure proper operational conditions and help in mitigating any issues that might arise due to environmental factors. This device provides essential data that can assist in making informed decisions related to flight safety and operational efficiency.
