Environmental Qualification
Section 10: Environmental Qualification (DO-160)
Definition
The process of demonstrating, through analysis and testing, that airborne equipment performs its intended function within its specified performance envelope when subjected to the environmental conditions defined by its installation location on the aircraft. Environmental qualification encompasses both the test program and the supporting analysis that together establish equipment suitability for the intended operating environment.
Where This Shows Up
Environmental qualification is distinct from certification testing in that qualification addresses the physical robustness and electromagnetic compatibility of the equipment, while certification testing addresses functional compliance with regulatory requirements. However, the two are interrelated: successful environmental qualification is typically a prerequisite for type certification. The primary standard for environmental test conditions and procedures is RTCA DO-160 (EUROCAE ED-14), which defines categories and severity levels for a comprehensive set of environmental tests.
