Open aviation-grade software stack
for autonomous, cooperative and safety-critical flight systems

Katya Aviation Stack, Inc is an engineering-first organization developing
next-generation aviation software infrastructure for:

• aircraft
• helicopters
• UAV / UAS
• eVTOL and Urban Air Mobility
• future autonomous air systems

We build below traditional avionics,
below centralized ATC,
and below cloud-dependent architectures.

Our mission is to create a distributed, autonomous, self-coordinating aviation layer
that enables aircraft to think, communicate, adapt, and survive — independently.

Modern aviation software is:

• centralized
• ground-dependent
• rigid
• slow to evolve
• opaque by design

Katya Aviation Stack is the opposite.

We design systems that are:

• on-board first
• peer-to-peer
• real-time deterministic
• physics-aware
• adaptive by nature
• open and auditable

We do not build “apps for drones”.
We build the nervous system of autonomous aviation.

Katya is not a single product.
It is a modular, composable aviation software ecosystem.

Each module can operate independently
or as part of a larger airborne intelligence system.

AirMesh is a low-latency, peer-to-peer communication protocol designed for direct
aircraft-to-aircraft interaction.

• direct air-to-air data exchange (no ground station)
• position, velocity and intent sharing
• distributed collision avoidance
• cooperative routing and spacing
• mesh-based airspace awareness

There is currently no global P2P standard for airborne coordination.
All aviation still assumes ground-based control.

AirMesh enables:

aircraft that negotiate with each other — autonomously.

Neuro-FCC is a new class of flight control system.

It is:

• NOT a classical autopilot
• NOT machine learning
• NOT a black box

It is an adaptive control augmentation layer that:

• learns pilot control behavior
• reproduces motor-reflex-like responses
• adapts in real time (<2 ms loop)
• compensates failures dynamically
• preserves explainability and determinism

Neuro-FCC allows each aircraft to develop
a personalized, resilient control signature.

Vortex Shield addresses one of the most dangerous helicopter flight regimes: Vortex Ring State.

• early vortex ring detection
• real-time airflow trend analysis
• predictive entry estimation
• automatic recovery control
• vibration and pressure feedback loops

No helicopter today has a dedicated, software-defined anti-vortex system.

We are building the first.

The Predictive Airflow Engine brings simplified real-time CFD into flight.

• airflow pattern estimation
• stall prediction before onset
• vortex formation forecasting
• turbulence anticipation
• dynamic angle-of-attack optimization

This system transforms aircraft from reactive machines
into predictive physical systems.

Katya introduces a radically new concept:

Aircraft as autonomous airspace nodes

Each aircraft:

• maintains a local airspace model
• shares state with peers
• negotiates priority and routing
• resolves conflicts cooperatively
• operates without centralized ATC

This architecture is inspired by:

• distributed systems
• swarm intelligence
• fault-tolerant networks

And it has no existing equivalent in civil aviation.

Katya Aviation Stack builds on and extends proven open-source ecosystems:

• ArduPilot
• PX4 Autopilot
• MAVLink / MAVSDK
• ROS / rosflight
• AirSim
• QGroundControl

• C / C++ — real-time, embedded, safety-critical
• Python — simulation, tooling, analysis
• Rust — selected safety and isolation modules

• deterministic execution
• bounded latency
• explicit failure modes
• minimal hidden state
• hardware-agnostic architecture

• Simulation-first validation
• Hardware-last deployment
• No cloud dependency
• No mandatory connectivity
• No opaque AI decisions

We believe:

Aviation autonomy must be local, explainable, and resilient —
or it should not exist at all.

Katya Aviation Stack develops safety-critical software.

• Security is treated as a first-class design constraint
• Responsible disclosure is mandatory
• Deterministic failure behavior is preferred over silent degradation

📩 Security contact: security@katya.ai

• Active research & development
• Public simulation-based demonstrations
• Modular open-core repositories
• Architecture-first documentation
• No vaporware — only working code

We actively collaborate with:

• aerospace engineers
• control systems researchers
• avionics developers
• academic institutions
• simulation and safety experts

We welcome:

• technical contributions
• research partnerships
• validation and peer review

We envision a future where aircraft:

• coordinate without ground dependency
• adapt like living systems
• understand their physical environment
• recover from failures autonomously
• share airspace intelligently
• operate as part of a cooperative airborne network

Katya Aviation Stack exists to make this future real.
