RTCA DO-160 defines environmental test conditions and procedures used to show how airborne equipment performs when exposed to the conditions it may experience in service. It is commonly referenced for aerospace equipment, avionics, aircraft systems, eVTOL, UAV, battery systems and other airborne hardware.
Resonate Testing supports DO-160 programmes with requirement review, environmental and mechanical testing, test planning, fixture development and engineering input. The scope is confirmed before quotation so the test plan reflects the equipment, installation environment, category requirements and acceptance criteria.
Programme-led approach: review of the equipment, installation environment, category requirements and pass/fail criteria before testing starts.
Integrated capability: environmental, vibration and shock testing can be planned as a connected sequence rather than isolated tests.
Clear compliance language: testing is scoped to supported sections and categories; the page should not be read as a claim of full DO-160 coverage, blanket accreditation or certification approval.

Environmental qualification programmes are most effective when the applicable RTCA DO-160 sections, equipment configuration, operating modes and acceptance criteria are defined before testing begins. Early technical review helps ensure the selected test procedures reflect the intended aircraft, avionics, UAV, eVTOL or aerospace application and generate meaningful qualification evidence. Share your RTCA DO-160 revision, equipment details, drawings, installation information and environmental requirements for review. Resonate Testing can assess test section selection, category requirements, monitoring requirements and reporting expectations before quotation.
RTCA DO-160 is not a single environmental test, but a framework of environmental conditions and test procedures used to qualify airborne equipment for aviation applications. A qualification programme that is suitable for one aircraft installation may not be appropriate for another.
Equipment installed within a cockpit, avionics bay, pressurised cabin, external pod, rotorcraft compartment, UAV payload bay or eVTOL platform can be exposed to very different combinations of temperature, altitude, vibration, humidity, fluid exposure, electromagnetic interference and power conditions. Test categories, severity levels and acceptance criteria are therefore typically determined by the equipment installation environment and intended aircraft application.
Failure to select the appropriate RTCA DO-160 categories can result in under-testing, over-testing, programme delays and increased certification risk. Defining the installation environment and qualification requirements early helps ensure that testing reflects realistic operating conditions and generates meaningful evidence of equipment performance, reliability and airworthiness.

The environmental conditions experienced by airborne equipment are heavily influenced by where the equipment is located within the aircraft. Systems installed within a temperature-controlled cockpit may experience very different operating conditions to equipment mounted externally, installed within an unpressurised bay or integrated into a rotorcraft platform.
This is one of the reasons RTCA DO-160 uses environmental categories rather than a single qualification profile. Installation environment, aircraft type, operating altitude, mission profile and equipment function can all influence which environmental conditions should be considered during qualification. Selecting representative environmental categories helps ensure that testing remains relevant to the intended application while avoiding unnecessary qualification activities.
While RTCA DO-160 has long been associated with traditional avionics programmes, the standard continues to be applied across a wide range of modern aerospace technologies. Environmental qualification activities are commonly considered during the development of UAV systems, advanced air mobility platforms, eVTOL technologies, aerospace sensors, communication equipment, power electronics and battery systems.
As aerospace platforms continue to evolve, environmental qualification remains an important method of evaluating performance under representative operating conditions. By understanding how equipment responds to environmental stress, manufacturers can generate valuable qualification evidence while supporting reliability, safety and aircraft integration activities throughout the development lifecycle.
Airborne equipment can experience a wide range of environmental conditions throughout its operational life. Ground handling, transportation, aircraft turnaround activities, altitude changes, vibration, electromagnetic environments and climatic conditions can all affect equipment performance. RTCA DO-160 provides a structured framework for evaluating how equipment responds to these conditions in a controlled test environment.
Understanding the difference between storage, transportation, ground operation and flight environments is an important part of qualification planning. This helps ensure that environmental testing remains representative of real-world operating conditions and supports meaningful performance assessment.
Environmental qualification is ultimately about understanding how equipment will perform throughout the complete aircraft operating lifecycle.
RTCA DO-160 is widely used during environmental qualification of airborne equipment installed on commercial aircraft, military aircraft, helicopters, UAVs, advanced air mobility platforms and eVTOL systems. The standard provides a structured method of demonstrating that airborne equipment can continue to perform when exposed to the environmental conditions likely to be encountered throughout its operational life.
Typical applications include:
The environmental conditions experienced by airborne equipment are largely influenced by where the equipment is installed within the aircraft. Equipment located within a temperature-controlled cockpit may experience very different operating conditions to systems installed in unpressurised compartments, external fairings, rotorcraft structures or UAV payload bays.
For this reason, RTCA DO-160 qualification programmes are typically developed around the aircraft installation environment rather than the equipment alone. Installation location, operating altitude, aircraft type, mission profile and functional requirements can all influence the environmental categories, test severities and monitoring activities applied during qualification.
Environmental qualification testing is often used to support equipment approval programmes, aircraft integration activities, development testing and customer qualification requirements. Defining the intended operating environment early helps ensure that testing remains representative of real-world aerospace conditions and produces meaningful evidence of equipment performance, reliability and environmental resilience.
Resonate Testing supports RTCA DO-160 environmental qualification programmes through a combination of climatic, mechanical and environmental testing services relevant to airborne equipment. We work with aerospace manufacturers, avionics developers, UAV suppliers, eVTOL programmes and advanced engineering teams to plan and execute environmental qualification activities aligned with aircraft operating environments and programme requirements.
Our environmental testing capabilities can support qualification activities involving temperature and altitude, humidity, vibration, mechanical shock, waterproofness, fluid susceptibility, dust and contamination exposure, corrosion assessment and related environmental conditions commonly considered within RTCA DO-160 test programmes. Testing activities can be coordinated through a single engineering team, helping maintain continuity from requirement review and test planning through to execution, inspection and reporting.
Whether supporting a single environmental assessment or a broader qualification campaign, we assist customers with category selection, test programme development, instrumentation planning, functional monitoring and qualification reporting to help generate meaningful environmental qualification evidence for airborne equipment.
Flexible testing capability. Integrated programme support. Aerospace-focused engineering expertise.
RTCA DO-160 provides a structured approach to environmental qualification for airborne equipment by defining a series of environmental, mechanical, electrical and electromagnetic test categories that represent the conditions encountered throughout the life of an aircraft. Rather than applying a single qualification profile to every product, the standard allows manufacturers and integrators to select the environmental conditions most relevant to the equipment’s intended installation and operating environment.
The conditions experienced by airborne equipment can vary significantly depending on where it is installed. Avionics located within a pressurised flight deck may operate in a relatively controlled environment, while equipment installed in unpressurised compartments, external fairings, rotorcraft structures, UAV payload bays or eVTOL platforms can be exposed to much harsher environmental conditions. RTCA DO-160 helps bridge this gap by providing environmental categories that reflect these different operating scenarios.
Each category is designed to evaluate how specific environmental stressors influence the performance, reliability and durability of airborne hardware. These stressors may include extreme temperatures, rapid thermal transitions, humidity, vibration, mechanical shock, altitude effects, water exposure, fluid contamination, sand and dust ingress, salt-laden atmospheres, aircraft power variations and electromagnetic interference. Together, these assessments provide a comprehensive understanding of how equipment is likely to behave during transportation, storage, ground operations and flight.
Selecting appropriate RTCA DO-160 categories is a critical part of any aerospace qualification programme. The chosen environmental conditions should accurately reflect the intended aircraft installation, mission profile and operational environment. Environmental qualification data generated through testing is commonly used to support equipment approval activities, aircraft integration programmes, design verification exercises and broader aerospace development projects. By aligning the test environment with the expected operating environment, manufacturers can generate evidence that demonstrates equipment suitability, supports risk reduction and provides confidence in long-term operational performance.
As aircraft technology continues to evolve across commercial aviation, defence aviation, advanced air mobility, UAV and eVTOL platforms, RTCA DO-160 remains one of the most widely recognised frameworks for demonstrating that airborne equipment can perform reliably in the challenging environments encountered throughout aerospace operations.

RTCA DO-160 is not a single environmental test. Qualification programmes are typically tailored to the intended aircraft installation environment, operating conditions and equipment function. Environmental conditions can vary significantly between flight decks, avionics bays, pressurised cabins, external aircraft locations, rotorcraft compartments, UAV payload systems and eVTOL platforms.
Installation environments should be reviewed early if equipment will experience temperature extremes, altitude changes, vibration, mechanical shock, water exposure, fluid contamination, electromagnetic interference or challenging aircraft power conditions. Test categories, severity levels and performance criteria may differ depending on the aircraft type, installation location and certification requirements. Confirm the required qualification approach before programme scope, test categories or acceptance criteria are committed.
Successful RTCA DO-160 qualification starts with understanding the aircraft installation environment.
RTCA DO-160 qualification activities often require multiple environmental, mechanical and electromagnetic assessments to demonstrate equipment performance under representative aerospace operating conditions. Coordinating climatic, vibration, shock and EMC testing within a single campaign helps reduce programme complexity and maintain continuity throughout the qualification process. Running testing through one engineering team helps align test planning, instrumentation, monitoring, reporting and technical review activities across the wider qualification programme.
For projects requiring multiple environmental assessments, temperature and altitude testing, vibration testing, shock testing, waterproofness assessments, fluid susceptibility evaluations and EMC testing can be planned as part of a structured RTCA DO-160 qualification campaign.
