RTCA DO-160 Section 20 Radio Frequency Susceptibility Testing
The RTCA DO-160 standard is widely recognized in the aerospace and defense industries as a key guideline for ensuring that avionics equipment, communications systems, and other electronic components meet stringent electromagnetic compatibility (EMC) requirements. Section 20 of this standard specifically addresses radio frequency (RF) susceptibility testing. This service ensures that electrical and avionic systems aboard aircraft are robust against the numerous sources of RF interference they will encounter in flight.
Given the critical role these systems play in airworthiness, compliance with DO-160 Section 20 is not only a regulatory requirement but also essential for maintaining operational reliability. The primary goal of this testing is to evaluate how well avionics and electrical components can withstand the electromagnetic environments they will encounter during flight.
In the aviation context, RF interference can originate from various sources including:
- Other aircraft electronic systems
- Ground-based communication equipment
- Natural atmospheric phenomena like lightning
- Man-made devices such as radar and satellite communications
The testing process aims to ensure that all components, from simple connectors to complex avionics assemblies, can continue performing their intended functions without degradation in performance or integrity. This is crucial for the safety and reliability of aircraft systems.
During RTCA DO-160 Section 20 testing, various types of RF signals are introduced into the test chamber under controlled conditions that simulate real-world environments. These tests assess how well the system responds to electromagnetic noise and whether any degradation in performance occurs as a result.
The primary topics covered by this service include:
- Identifying potential sources of interference
- Evaluating system immunity to RF signals
- Assessing compliance with applicable international standards such as ISO, IEC, and EN
- Ensuring that the tested equipment can function reliably in the presence of electromagnetic interference (EMI)
The testing process is designed to ensure that the avionics and electrical systems meet not only regulatory requirements but also stringent quality control standards. This comprehensive approach ensures that all components are robust against the myriad sources of RF interference they will encounter during flight.
| Test Parameters | Description |
|---|---|
| Frequency Range | Tests cover a wide range, typically from 10 kHz to 8 GHz, depending on the specific requirements of the component or system being tested. |
| Field Strength | The testing is conducted at various field strengths that simulate real-world conditions, ensuring that the equipment can withstand high levels of electromagnetic interference. |
| Test Duration | Durative tests are performed to ensure long-term reliability under continuous exposure to RF fields. |
| Environmental Conditions | The tests are conducted in controlled environmental conditions that replicate the operational environment of the aircraft, including temperature and humidity variations. |
In addition to ensuring compliance with regulatory standards, this service also plays a crucial role in maintaining the reliability and safety of aviation systems. By identifying potential issues early in the development process, it allows manufacturers to make necessary adjustments before products are deployed, thus minimizing risks associated with electromagnetic interference.

Environmental and Sustainability Contributions
The testing of avionics and electrical systems for compliance with RTCA DO-160 Section 20 has significant environmental and sustainability benefits. By ensuring that these systems can withstand the rigors of flight, we help reduce the risk of in-flight failures due to electromagnetic interference (EMI). This not only enhances safety but also extends the operational life of aircraft, leading to reduced fuel consumption and lower emissions per passenger mile.
The testing process itself contributes positively to sustainability by:
- Preventing Failures: By identifying potential issues early in the development cycle, we help prevent failures that could lead to costly repairs or replacements on aircraft already in service.
- Energy Efficiency: Ensuring reliable performance under all conditions helps reduce the overall energy consumption of aviation systems.
- Resource Optimization: By extending the life of components through robust testing, we help optimize resource use and minimize waste.
The aerospace industry is increasingly focused on reducing its environmental footprint. Compliance with standards like RTCA DO-160 Section 20 helps to achieve this goal by ensuring that avionics and electrical systems are designed for longevity and reliability. This, in turn, supports broader sustainability efforts within the aviation sector.
