Avionics Testing Solutions

What Avionics We Test

Avionics (aviation electronics) is the electronic and electrical equipment that helps operate aircraft and spacecraft, built to work where environmental conditions would exceed ordinary systems. Averna tests these systems at both the Line Replaceable Unit (LRU) and Shop Replaceable Unit (SRU) level.

Avionics testing covers an aircraft's electronic systems, such as:

Radios and communication
Flight management and computing systems
Flight control systems
Navigation systems
Radio altimeters
Surveillance equipment
Cockpit display and control systems
Sensors and onboard electronic equipment

Averna also tests mechanical and hydraulic components and actuators, not only electronics. Coverage also extends to Unmanned Aerial Vehicles (UAVs), drone avionics and Electric Vertical Take-Off and Landing (eVTOL) systems, which run the same flight-critical electronics as crewed aircraft in smaller airframes.

Avionics Testing Coverage Across the Lifecycle

Testing must change as an avionics program matures. Averna supports every stage with the right approach.

Phase 01
Embedded validation

Early in a program, designs must be proven before hardware exists. Averna validates avionics software and system interactions in real time, so problems surface before physical prototypes are built.
Phase 02
Production testing

In series manufacturing, every unit must meet spec before it reaches the aircraft. Averna automates functional test and data capture to keep quality consistent at volume.
Phase 03
Maintenance and overhaul

In service, avionics must be repaired and returned to airworthy condition. Averna gives airlines and maintenance providers the means to verify repaired units before they go back on the aircraft.
Phase 04
Obsolescence management

When original equipment leaves the market, test capability must not leave with it. Averna keeps legacy programs supportable and protects long-term continuity.

Averna's avionics test platforms are proven in-house systems, each built for a specific avionics test need.

Board and Component Testing

Averna tests avionics electronics at board level, catching defects before units are assembled. In-circuit test verifies each component on a populated circuit card assembly. Relay and circuit breaker validation runs on the MAGSET Series.

Signal, RF & Avionics Communications

Averna records and replays the full GNSS spectrum, keeping real interference intact so receivers face authentic conditions in the lab. On the communications side, Averna tests SATCOM transceivers and defense-grade communication modules across the RF chain, verifying signal integrity before integration.

Electromagnetic Environmental Effects (E3)

Avionics equipment must keep operating through electromagnetic disturbances such as lightning and high-intensity radiated fields. Averna designs test systems aligned with E3 requirements including DO-160 and MIL-STD-464, building these constraints into the test program.

Power and Propulsion

New propulsion architectures bring high-voltage batteries and power electronics into the airframe. Averna validates these systems under real operating stress, with coverage dedicated to eVTOL programs.

CMC Electronics operates more than 100 test stations to validate a wide range of avionics products, including GPS systems, flight management systems, electronic control units, and smart cockpit displays. To support future production needs, the company launched its Expertus initiative to standardize test environments and increase automation across the factory.

Key outcomes:

Introduced a common test architecture that simplified the deployment and maintenance of avionics test stations.
Automated test execution and data collection to improve efficiency and reduce manual processes.
Centralized production and test data through Proligent Analytics, giving teams near real-time visibility into quality and manufacturing performance.

Working alongside CMC, Averna helped create a flexible avionics test environment capable of supporting evolving product lines while maintaining high quality standards. The new platform provides a consistent foundation for testing, troubleshooting, and production decision-making.
