- Safety-critical avionics complexity: Flight controls, navigation, communication, radar, power and mission systems increasingly combine software, FPGA/programmable hardware and networked electronics.
- High development-assurance rigor: DO-178C and DO-254 require disciplined lifecycle processes, defined objectives, evidence and traceability appropriate to the applicable assurance level.
- Hardware/software interaction: Airborne systems require consistent allocation and traceability between system requirements, software requirements, hardware requirements and implementation.
- Certification evidence burden: Planning, reviews, verification results, configuration management, problem reports, traceability and compliance evidence must remain consistent throughout the lifecycle.
- Complex airborne hardware: FPGA, ASIC, COTS devices and other complex electronic hardware can introduce verification, configuration and assurance challenges.
- Real-time and deterministic behavior: Flight-control, navigation, communication and mission functions depend on predictable timing, fault handling and robust interfaces.
- Sensor and navigation dependence: GNSS, inertial, radar and environmental sensors influence flight decisions and require appropriate failure detection, redundancy and degraded-mode behavior.
- Power integrity: Aircraft and UAV power distribution and conversion failures can propagate into multiple safety-critical loads.
- Connected and autonomous platforms: UAVs, autonomous flight systems and connected avionics increase the interaction between safety, security, communications and operational behavior.
- Certification schedule pressure: Late safety-process gaps or missing objective evidence can create costly rework and certification delays.
