DO-160 Environmental Testing: A Practical Map for Avionics Hardware
RTCA/DO-160 defines environmental conditions and test procedures for airborne equipment. Programs fail when teams treat it as a fixed checklist instead of a category selection tied to installation.
How to scope a campaign
- Get the installation environment from the airframer / STC context (temperature, altitude, vibration, power).
- Select applicable DO-160 sections and categories — not every section for every box.
- Align EMC sections with aircraft power quality and RF environment assumptions.
- Plan specimen configuration: connectors, bonding, software mode during tests.
- Keep a compliance matrix linking requirements → categories → reports.
Sections teams underestimate
- Power input / audio frequency conducted susceptibility — fails from cheap PSUs
- Vibration / shock — mechanical fixity and connector strain relief
- Waterproofness / fluids — seals and conformal coat assumptions
- RF susceptibility — cable coupling and enclosure apertures
FAQ
Is DO-160 a certification by itself?
DO-160 provides test methods. Aircraft certification credit depends on the certification basis and applicant’s plan with the authority / airframer.
