Assuring Reliability in Flight-Critical Electronics
Avionics and aircraft electrical systems are essential for navigation, communication, and flight control. Their reliability is vital to flight safety and must be demonstrated under extreme operating and electromagnetic environments in accordance with RTCA DO-160 and equivalent standards.
BQCIS performs comprehensive EMC/EMI verification and environmental qualification testing to confirm that onboard systems remain stable under radiated and conducted interference, lightning transients, and high-intensity radiated fields (HIRF). Our accredited facilities simulate altitude, temperature, vibration, and humidity conditions representative of real-world aircraft operation.
From component design through certification, we help OEMs and Tier-1 suppliers prove airworthiness, secure regulatory approvals, and guarantee that flight-critical electronics operate flawlessly throughout the service life of the aircraft.
Key Verification Activities
Key Benefits of Avionics Testing
Regulatory Airworthiness
Demonstrates compliance with RTCA DO-160, MIL-STD-810, and FAA/EASA qualification requirements for flight-critical equipment.
Reduced Program Risk
Early detection of design or component weaknesses through stress and EMC screening minimizes costly re-engineering and certification delays.
Improved System Reliability
Environmental endurance testing ensures electronic systems maintain functionality and data integrity across mission profiles.
Independent Verification
Third-party validation by BQCIS adds traceability and credibility to manufacturer test data for OEM and authority acceptance.
Success Story
DO-160 Testing Secures Avionics Component Qualification
A supplier developing a next-generation flight data recorder required complete DO-160 qualification to verify resistance to vibration, temperature, and electromagnetic stress.
BQCIS executed combined environmental and EMC testing, including multi-axis vibration, rapid temperature cycling, and lightning transient simulation, replicating in-flight extremes.
The recorder met all DO-160 criteria. BQCIS issued a qualification report accepted by the OEM and aviation authority, enabling the product’s installation approval and commercial deployment.
