What is DO-178C?
DO-178C, formally known as Software Considerations in Airborne Systems and Equipment Certification , is the internationally recognized guidance for developing and verifying safety-critical airborne software.
It provides the framework required to demonstrate that airborne software performs its intended functions safely and reliably throughout the certification lifecycle.
Airworthiness
Supports the evidence required to demonstrate software safety and airworthiness.
Certification
Provides a structured framework for certification authorities including FAA, EASA and DGCA.
Traceability
Establishes rigorous relationships between requirements, design, code and verification.
Why DO-178C Matters
Safety-critical airborne software demands more than functional correctness. It requires objective evidence, disciplined processes and complete lifecycle traceability.

Development Assurance Levels
DO-178C defines five software assurance levels based on the potential effect of software failure on the aircraft.
| DAL Level | Failure Effect | Assurance Level |
|---|---|---|
| DAL A | Catastrophic — e.g. loss of aircraft | Highest |
| DAL B | Hazardous / Severe-Major | High |
| DAL C | Major | Medium |
| DAL D | Minor | Low |
| DAL E | No effect on safety | None required |
