Fly-By-Wire Control Systems
High-integrity, fault-tolerant flight control architectures engineered for next-generation commercial, defense, and space launch vehicles. Certified for CAT-A criticality with adaptive control laws and real-time envelope protection.
System Overview
AeroVance's Fly-By-Wire (FBW) platform replaces traditional mechanical flight controls with electromechanical interfaces, enabling precise, computationally enhanced aircraft handling. Our architecture leverages triple and quadruple modular redundancy, real-time Linux/VxRTOS hybrid environments, and AI-assisted control law adaptation to maintain optimal stability across extreme flight envelopes.
Designed for seamless integration with existing OEM airframes, our FBW systems deliver reduced structural weight, minimized pilot workload, and enhanced safety through automated envelope protection, stall prevention, and cross-axis coupling mitigation.
- Deterministic latency under 2ms for control loop execution
- Adaptive control laws with real-time sensor fusion
- Hardware/software partitioning compliant with ARP4761 guidelines
- Support for conventional, canard, and tailless configurations
Architecture & Redundancy
Our FBW architecture follows a distributed, federated control topology. Flight control computers (FCCs) interface directly with sensor suites and actuator channels via ARINC 429, MIL-STD-1553, and AFDX networks. The system maintains continuous operational capability through hardware partitioning and automatic fault detection, isolation, and recovery (FDIR).

Actuation & Output
Redundancy management operates on a voting logic with graceful degradation. In the event of dual-channel failure, the system automatically reverts to a direct-law backup mode while maintaining basic longitudinal and lateral control authority.
