BQCIS

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

EMC & HIRF Testing (DO-160)

Full electromagnetic compatibility verification to RTCA DO-160, including radiated/conducted emissions and susceptibility, high-intensity radiated field (HIRF), and lightning transient response. Ensures avionics systems maintain functionality and safety margins in high-energy environments.

Environmental Stress Screening & Qualification

Comprehensive qualification per DO-160 environmental categories A–Z. Components undergo altitude, vibration, thermal shock, and humidity cycling to expose latent defects before installation—improving reliability and reducing in-service failures.

Key Benefits of Avionics Testing

Benefit 1

Regulatory Airworthiness

Demonstrates compliance with RTCA DO-160, MIL-STD-810, and FAA/EASA qualification requirements for flight-critical equipment.

Benefit 2

Reduced Program Risk

Early detection of design or component weaknesses through stress and EMC screening minimizes costly re-engineering and certification delays.

Benefit 3

Improved System Reliability

Environmental endurance testing ensures electronic systems maintain functionality and data integrity across mission profiles.

Benefit 4

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

The Challenge:

A supplier developing a next-generation flight data recorder required complete DO-160 qualification to verify resistance to vibration, temperature, and electromagnetic stress.

Our Solution:

BQCIS executed combined environmental and EMC testing, including multi-axis vibration, rapid temperature cycling, and lightning transient simulation, replicating in-flight extremes.

The Result:

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.
