A Quick Guide To RTCA Do-160 Testing

Unless you are an expert in aerospace and avionics, it is highly likely that you have never heard of RTCA Do-160. This is one of the most important tests that are aimed at verifying and determining the suitability of particular airborne for some particular uses or functions. It evaluates the capability of airborne equipments to resist conditions that it will encounter in the real operation. RTCA Do-160 lays down the environmental test and procedures criteria for testing of airborne equipments. It covers all types of aircraft ranging from helicopters, jumbo jets, light aircraft and SST aircraft categories.
The document comprises of 26 sections and additional three appendices. There are various test covered under this section including electrostatic and lighting discharge, radio frequency susceptibility, power input and vibration. This testing is mostly coordinated with EUROCAE testing. Expert providers of this testing service can simultaneously run tests through their lab so as to ensure that they offer the best service. Others will even allow you to witness the testing process. Many others will also want the testing to be witnessed by authorized FAA representative.
What's the purpose of RTCA Do-160 testing?
The main purpose of this test is determining the airborne equipment performance characteristics in environmental conditions which are truly representative of those that are likely to be encountered in the equipment's airborne operation.
There are various providers of this testing service but it would be wise if you hire one who is widely experienced in the area.The reliable RTCA Do-160 testing service providers even ensure that the testing is witnessed by FAA representatives or other independent agency. A consultant Designated Engineering Representative (DER) may be employed to act as independent witness to approve, or recommend the approval of the required technical data to FAA. A consultant Designated Airworthiness Representative (DAR) can also be appointed under 14 CFR § 183.33 to perform the inspection, testing and examination services which are required for the issuance of certificate.
The RTCA Do-160 testing standards in use were originally developed in 1980 built have undergone several revisions. Experts advise that the user of this standard should interdependent of the standard determine how much additional test margin should be allowed because of the testing conditions uncertainty and each test measurement. Also, the report from the RTCA Do-160 testing should strictly adhere to the format which is prescribed for that purpose. Among others, it may cover the following
> Cable configurations - wiring diagram, shielding, type and length of test harness
> Test setups - which may be block or schematic diagrams with photos
> Mode of operation during the cable bundle tests
> Simulated or actual loads
> All test levels and waveforms
> Applied transients
> Failed/pass criteria
The best provider of RTCA Do-160 testing service is one who is a full RTCA member and fully participates in the development as well as revision of this vital document. This way, the testing service provider will be able to keep you well-informed of all the latest changes in the market.
