Thermal Expansion Limits in Aerodynamic Thermoplastic Housing Design
Accommodate thermoplastic thermal expansion using kinematic sliding mounts and recessed lap joints to prevent out-of-plane buckling and boundary layer tripping.
RTCA DO 160
Meaning
Environmental testing standards for airborne equipment published by the Radio Technical Commission for Aeronautics establish environmental conditions and test procedures for commercial avionics. Compliance with RTCA DO 160 verifies hardware resistance to temperature, vibration, lightning strikes, and radio frequency interference. The standard stops at environmental testing and does not cover software safety assurance or system architecture design.
Testing Standard
Aerospace supply contracts require full laboratory certification prior to avionics installation. Meeting RTCA DO 160 criteria validates equipment readiness for installation on commercial transport aircraft across global markets. When avionics units fail environmental stress tests, suppliers must redesign thermal heat sinks or electrical shielding before securing airworthiness approvals.
Aviation procurement agreements prohibit equipment delivery until certified test reports confirm compliance across required operational categories.
Channel Clearance
Commercial distribution channels for avionics require strict adherence to regulatory testing protocols. Documented RTCA DO 160 compliance enables component suppliers to access international airline retrofit markets. Certification costs are factored into original product pricing models to offset testing lab fees.
Noncompliance Penalty
Supply contracts enforce strict financial remedies for uncertified components. Failure to present valid RTCA DO 160 test documentation results in contract cancellation and immediate rejection of delivered shipments. Hardware suppliers bear all financial losses associated with delayed aircraft integration.
