DO-160 – Environmental Testing for Aerospace Equipment
DO-160 is an international standard developed by the RTCA (Radio Technical Commission for Aeronautics) that defines environmental testing requirements for airborne equipment. It is widely used in the aviation industry to certify the durability and performance of avionics, aircraft lighting, communication systems, and electronic components under various environmental conditions.
Compliance with DO-160 is essential for manufacturers of military and commercial aerospace systems, ensuring that all onboard equipment operates safely and reliably in extreme conditions.
Why is DO-160 Important?
- Ensures that aerospace equipment functions reliably in harsh operational conditions.
- Standardizes environmental testing procedures across the aviation industry.
- Prevents system failures caused by temperature, vibration, humidity, and electromagnetic interference.
- Validates compliance with safety regulations for commercial, military, and unmanned aircraft.
- Extends the lifespan of onboard electronics and lighting systems by stress-testing them under realistic flight conditions.

Key Environmental Tests Under DO-160
- Temperature and Altitude Testing – Evaluates performance under extreme high and low temperatures, rapid temperature changes, and high-altitude conditions.
- Humidity Testing – Assesses resistance to moisture and condensation inside aircraft.
- Vibration and Shock Testing – Ensures durability against turbulence, landing impact, and in-flight vibrations.
- Electromagnetic Interference (EMI/EMC) Testing – Verifies that electronics do not interfere with aircraft communication and navigation systems.
- Waterproof and Fluid Susceptibility Testing – Tests resistance to rain, water spray, and exposure to aviation fluids such as fuel and hydraulic oil.
- Lightning and Power Surge Testing – Simulates the impact of lightning strikes and power fluctuations on avionics and electrical systems.
