DO-160 is a standard for environmental testing of avionics published by RTCA, the American Radio Technical Commission for Aeronautics.

DO-160, Environmental Conditions and Test Procedures for Airborne Equipment, published by RTCA (Radio Technical Commission for Aeronautics), is the international standard that defines environmental test conditions and applicable test procedures and criteria for avionic equipment to determine their performance characteristics.

All the manufacturers of aeronautic products must meet the requirements of this standard to ensure that their equipment will operate correctly when airborne.

 

The DO-138, its precursor, has been used as a standard for environmental testing since 1958.

The DO-160 document was first published on February 1975, since then the standard has undergone subsequent revisions up through the current Revision G.

SC-135, the Special Committee for Environmental Testing, established on October 1977, continues to maintain RTCA DO-160.

DO-160G was published in December 2010, and an update of the Users’ Guide material for this document is in development, with the aim of providing rationales, guidance and background information for the environmental, test procedures and requirements, as well as lessons learned from aircraft and laboratory experience.

As the realities of equipment operation under actual environmental conditions are better understood and new needs arise within the aviation community, RTCA/DO-160 has been revised to address the emerging and improved test techniques.

The categories that have been developed over time reflect a reasonably mature understanding as to the severity of the environmental stresses, the degrees of mitigation achievable in the design of an installation, and the robustness that must be designed into equipment in order to perform in the operating environment.
