DO-160 EMC and Environmental Testing
RTCA DO-160 is the industry recognized standard for avionics qualification. It covers EMC and the evaluation of equipment for power input variations and transients. It also tests for a wide range of environmental stresses. The U.S. Federal Aviation Administration (FAA) and European Union Aviation Safety Agency (EASA)reference DO-160 as the requisite qualification for aircraft certification. Of the 25 sections listed in DO-160, nearly all are covered by services at Elite. In addition, aircraft manufacturers such as Boeing, Airbus, Embraer, and others include DO-160 requirements, plus their additional qualification testing and here again, Elite is setup to support these OEM specific requirements.
Elite services for DO-160 and related aviation testing include:
- Test plans and procedures written by experienced EMC experts.
- EMC testing to Sections 15-22, and 24 for the most current DO-160G plus all legacy revisions DO-160C/D/E/F.
- DO-160 EMC, electrical, and environmental stress testing at One Location.
- Final test reports are recognized and results accepted by all major aircraft OEMs.
DO-160 Facilities, Chambers, Equipment
Our DO-160 EMC testing is performed in state-of-the-art absorber lined shielded chambers (ALSE), reverberation and mode tuned/stirred chambers, as well as several specialty ground-plane test benches. The amplifiers, receivers, and other equipment used for these tests are the best in the industry and able to perform nearly all tests in Sections 15-22.

EMC Testing Technical Information
What is the RTCA DO-160?
The DO-160 standard was developed by RTCA to ensure airborne equipment meet the airworthiness requirements for fixed-wing and rotary-wing aircraft. DO-160 includes 23 sections of test methods covering all aspects of the aircraft environment from temperature, altitude, shock, and vibration to RF emissions, lightning effects, and flammability.
The current revision is DO-160G and it has become a common testing standard recognized throughout the aerospace industry. Before DO-160, aerospace manufacturers could each require different sets of tests to verify proper equipment operation onboard their aircraft. Currently, the U.S. FAA recommends DO-160G testing for many equipment types used on aircraft. Elite regularly participates in the DO-160 development committee to provide input on the latest test methods and technology considerations.
What is HIRF?
A high-intensity radiated field (HIRF) is radio-frequency energy of a strength sufficient to adversely affect either a living organism or the performance of a device subjected to it. A microwave oven is an example of this principle put to controlled, safe use. Radio-frequency (RF) energy is non-ionizing electromagnetic radiation – its effects on tissue are through heating. Electronic components are affected via rectification of the RF and a corresponding shift in the bias points of the components in the field.
How is Lightning Tested on Aircraft?
DO-160 testing applies to most airborne equipment and is directly referenced as a means of verifying compliance with numerous regulatory requirements. As stated in Section 1.0, “the test categories defined in DO-160 are intended to encompass the full spectrum of environmental conditions that airborne equipment may experience – from benign to very hostile” and “some of the environmental conditions and test procedures contained in DO-160 are not necessarily applicable to all airborne equipment.” Ultimately, it is the specific performance standards that determine which test categories are required to your product.
