Certifiable Flight Control

Triple redundancy for manned and unmanned flight

Designed for Certification

Designed for Certification

Developed under DO-178C and DO-254. The architecture is designed for DAL A software and hardware allowing distributed redundancy, for manned aircraft,Part 23 and Part 25 aircraft, SC-VTOL and certified UAS.
Vehicle Management Unit

Vehicle Management Unit

A flexible software architecture runs all kinds of programs beyond flight control. The 4x can act as the aircraft's vehicle management system (VMS) as well as its flight controller, reducing the number of boxes and the wiring on board.
Fly-by-Wire and Autonomous Modes

Fly-by-Wire and Autonomous Modes

The 4x unit supports piloted fly-by-wire control for manned aircraft and eVTOL, and fully autonomous operation for UAS. Control phases, transitions and failsafes are configurable for tiltrotor, tiltwing, lift & cruise, multicopter, helicopter and fixed-wing designs.

Ready for any vehicle

Veronte Autopilot 4x adapts to any aircraft layout: fixed-wing, VTOL, multirotor, helicopter, coaxial and eVTOL, as well as UGV and USV. Any of them can use a single unit or several units in distributed redundancy sharing a common architecture.

User-programmable redundant flight controller

Advanced customization tools give aircraft manufacturers full control over the 4x. Control laws, navigation, failsafes, automations and mission logic can be defined in three ways, from model-based design to fully custom software, to match each certification strategy.

Model-based design

Model-based design

Control laws, navigation logic, failsafes and automations are built with graphical block diagrams. The output is a Parameter Data Item (PDI) aligned with DO-331, so verification of the application layer focuses on parameters against requirements instead of C-code structural coverage.

Custom C++ code

Custom C++ code

Proprietary C/C++ algorithms run on a dedicated processor core as Custom Executable Object Code (EOC), alongside certified Veronte software. User code does not compete for platform resources and can be modified and re-verified independently. It communicates and shares data with the Veronte software.

Full custom software

Full custom software

Integrators can run their own software or RTOS on the Primary lane while certified Veronte software runs on the Monitor and Recovery lanes as a safety monitor. The bare-metal platform is deterministic, and BSL and SDK licenses are available.

Safety & Certification

Designed and manufactured to the highest aerospace safety standards, Veronte Autopilot 4x is designed for DAL A and suited for Part 23 and Part 25 aircraft, powered lift under EASA SC-VTOL, certified UAS and defense applications. Designed for NDAA and the Blue UAS list, with trusted supply chains.

  • DO-178C & DO-254

    Development follows ARP4754B and ARP4761A for systems and safety, DO-178C and DO-331 for software, DO-254 for hardware and DO-160G for environment, with DAL A compliance levels. Certification datapack is available for the platform software, including PSAC, PHAC, SAS, SCI, safety analyses, test reports and all required documentation.

  • SC-VTOL, Part 23 & Part 25

    Suited for Part 23 and Part 25 aircraft and powered lift under EASA SC-VTOL, as well as certified UAS and defense programs. The architecture supports EASA SC Light UAS, SORA high-SAIL operations and NATO STANAG 4703 for UAS certification.

  • DO-160G Environmental

    Environmental qualification to DO-160G covers temperature, vibration, shock, humidity, power input, lightning and RF susceptibility. The unit operates from -40 °C to 65 °C, with EMI/EMC shielding and HIRF protection for demanding flight conditions.

Embedded and/or distributed redundancy

Embedded and/or distributed redundancy

Veronte Autopilot 4x integrates three lanes with two processor types in a single 737 g unit. Each lane has its own mixed-technology IMUs, magnetometers, barometers and GNSS receiver and runs its own GNC. The Monitor checks system health and selects the lane in control via hardware multiplexers, switching to Recovery without affecting actuators.

Distributed Across the Airframe

For maximum survivability, two or more units can be installed in separate airframe zones in distributed redundancy (DRx), linked through the SAIL Bus (CAN XL). Isolated power rails, duplicated buses and independent flight termination outputs remove any single point of failure at unit level. Both configurations can be used in any aircraft.

Aircraft-grade connectivity

ARINC 429 & TSN Ethernet

ARINC 429 & TSN Ethernet

Native avionics interfaces connect the 4x directly to aircraft systems: ARINC 429 with 4 transmitters and 8 receivers, 2 TSN Ethernet ports and 8 CAN FD ports, configurable as independent buses or redundant channels.

Every bus duplicated

Every bus duplicated

Two MIL-DTL-38999 connectors (J1 and J2) carry duplicated, isolated RS232, RS485, CAN and I/O lines. If a complete harness or connector is lost, the second channel keeps every lane connected and the aircraft keeps flying.

Redundant power inputs

Redundant power inputs

Four power inputs, two on each connector, accept 8 to 54 V DC and connect directly to 12, 28 and 4 8V aircraft buses. Power input is qualified to DO-160G Section 16, Category B, at 28 V DC. Each input can be fed from a separate battery or regulator, so the loss of a power rail never interrupts operation.

Peripheral compatibility

Veronte Autopilot 4x integrates with the Veronte ecosystem and third-party equipment: LOS, 4G/LTE, Satcom and Starlink terminals, radar and vision for detect and avoid, ARINC 429 and TSN avionics, and CAN FD actuators and ESCs.

Advanced performance

Advanced autonomy, navigation and safety functions for manned and unmanned aircraft, built into every Veronte Autopilot 4x.

GNSS denied navigation ▾

Inertial navigation combined with wind estimation minimizes position drift when GNSS is lost or jammed. Veronte Vision PNT navigation or FOG IMUs can be added to further improve accuracy in GNSS-denied environments.

Redundant GNSS heading ▾

Triple redundant GNSS receivers with native heading provide two independent GNSS heading sources for accurate heading and attitude without relying only on magnetometers, reducing sensitivity to magnetic interference. Redundant pitot and static ports add reliable air data.

Swarm & multi-drone control ▾

Supports multiple aircraft and control stations operating in a shared network. The built-in SRC module enables formation flight with relative positioning, coordinated missions and seamless handover of aircraft between operators.

Fly-by-camera control ▾

Interfaces with a gimbal so the aircraft follows the camera pointing direction, letting the operator guide the flight intuitively. Altitude can be held or adjusted according to gimbal orientation.

Sense and avoid integration ▾

Embedded avoidance algorithms adjust the route in real time to keep clear of traffic and obstacles. Detection uses the built-in ADS-B module and can be extended with external radar and vision systems.

Internal ADS-B and Remote ID ▾

Built-in ADS-B and Remote ID modules work in In and Out modes, broadcasting the aircraft position and receiving nearby traffic data. The built-in SRC (Short Range Communications) module can be configured as Remote ID, in line with FAA 14 CFR Part 89 and EU Regulation 2019/945 Part 6, or for swarming and formation flight.

Integrated flight data recorder ▾

Each lane records flight data on its own internal memory, rated down to -40 °C. Variables and logging rates are configurable, with continuous or event-based logging for post-flight analysis and certification evidence.

LOS & BLOS connectivity ▾

Compatible with LOS datalinks and with BLOS communications through the built-in LTE modem with eSIM, Satcom or Starlink. Redundant channels can be configured for mission-critical links, fleet management and UTM integration.

Mission computer integration ▾

Onboard mission computers connect through STANAG 4586 to send high-level commands, receive real-time data and run advanced autonomy algorithms, while the 4x keeps full authority over flight control.

Geofencing, geocaging & FTS ▾

Native geofencing and geocaging keep the aircraft inside approved airspace and out of restricted zones, using geozone data in line with EN 4709-003 and EUROCAE ED-269. An independent flight termination output (FTS) provides a fail-safe action in case of total system failure.
