Avionics - Flight Management Systems: Market Size & Forecast 2026

The global flight management systems (FMS) market is valued at USD 6.0 billion in 2025 and projected to reach USD 8.7 billion by 2035, expanding at a CAGR of 3.8%. FMS technology is undergoing a transformative shift driven by software modularity, AI-driven optimization, and integrated modular avionics (IMA) architectures. Key procurement inflections include connectivity mandates, cybersecurity regulations, and software licensing models. > **Analyst Take.** The FMS market is bifurcating into legacy hardware replacement (1-2% CAGR) and AI-native software-driven growth (8-10% CAGR). Buyers anchored to traditional hardware contracts will face 25-30% higher software refresh costs by 2030. The inflection point is 2027, when 60%+ of new aircraft will ship with AI-optimized FMS. Procurement teams must reposition toward software-defined architectures now to avoid platform lock-in.
