Alten-India specializes in embedded FADEC systems, leveraging model-based development (MBD), software implementation, and verification for safety-critical applications. We provide expertise in requirements, design, Unit testing, Software-software integration testing, Hardware-software integration testing, System testing and DAL A certification to ensure compliance and reliability. Our services has enabled to deliver scalable, maintainable, and high-performance engine control solutions across multiple platforms and variants to our customer

Key Challenges

• Safety & Compliance: Every software update must maintain DAL A certification under DO-178C, integrated with system safety processes (ARP4754A, ARP4761A).
• Multi-Platform Complexity: FADEC software must support baseline engines and derivative variants without divergence, managing variant-specific requirements, and architecture differences.
• Traceability & Integration: Ensuring end-to-end traceability across system requirements, software requirements, safety analysis, and verification artifacts for all variants.
• Efficient Verification: Determining regression scope and executing verification across multiple platforms while ensuring 100% structural coverage for critical functions.
• Controlled Fleet Introduction: Coordinating configuration management, documentation, and release processes to support global operators safely and consistently.

Solution:

1. Change Request Triage: Centralized process evaluates impact, safety, and certification implications.
2. System Safety & Impact Assessment: Functional and safety analyses updated for all affected variants.
3. Requirements & Design:
   • Common core modules for all engine variants
   • Variant-specific parameters or modules
   • Full traceability across requirements, system safety, and verification artifacts
4. Software Implementation & Verification:
   • Coding standards and peer reviews
   • Unit testing, Hardware/software integration testing, System testing and automated regression testing per variant
   • Independent verification for DAL A critical functions
5. Configuration & Certification Control:
   • Centralized versioning for baseline and variant software
   • Documentation, service bulletins, and regulatory coordination

Benefits Delivered:

• Safety Integrity Maintained: All updates verified against system safety and certification standards.
• Scalability Across Engine Families: Modular architecture reduce duplication and ensure consistent quality.
• Predictable, High-Quality Updates: Centralized process and traceability improve reliability and reduce rework.
