The Importance of Thermal Altitude Testing

During thermal altitude testing, the equipment is placed inside an altitude chamber that simulates the extreme conditions found at high altitudes. The chamber has an efficient airflow system that maintains temperature, and vacuum and vent valves are automatically controlled to precisely simulate the altitude conditions that will be faced in flight. The response of the item is then measured against various factors to ensure that it meets specific criteria and product requirements.

The main goal of thermal altitude testing is to prevent critical component failure, which could result in catastrophic consequences. By demonstrating the ability to perform reliably under any atmospheric or environmental condition, this testing also assures purchasers of the superior quality of the product. Furthermore, thermal altitude testing helps verify that the equipment meets the high aerospace requirements set by industry experts and regulating bodies, such as RTCA-DO-160 and MIL-STD-202, which certify that the equipment can endure certain conditions it might face.
