The Honeywell Anthem flight deck and the cloud-connected avionics suite designed for aircraft that do not exist yet

Honeywell’s Anthem avionics suite is a software-defined, cloud-connected flight deck platform designed to serve aircraft types that don’t yet exist. Rather than building purpose-specific avionics for each new vehicle category, Anthem provides a single scalable architecture that can support everything from four-seat eVTOLs to autonomous cargo drones to hybrid regional airliners. Multiple advanced air mobility programs, including Lilium, Vertical Aerospace, and Pipistrel (now Textron eAviation), have already selected it.

Why Can’t Existing Avionics Handle Next-Generation Aircraft?

Today’s avionics landscape is category-specific. Garmin’s G1000 and G3000 dominate certified general aviation. Collins Aerospace serves business jets and airlines. Honeywell’s own Primus Epic powers large-cabin business jets. Each system was engineered for a narrow aircraft class, and none of them transfer well outside it.

That model worked for seventy years of jet aviation. Design the airplane, pick the matching avionics, certify the package. But the current wave of new aircraft types — electric vertical takeoff and landing vehicles, hybrid regional airliners, autonomous cargo drones, supersonic business jets, urban air taxis — creates an unsustainable demand for bespoke flight decks. Every one of those vehicles has different requirements, and the traditional approach doesn’t scale.

What Makes Anthem Architecturally Different?

Announced in 2021, Anthem is not a single box bolted into a panel. It is a modular hardware platform running a common software layer. The hardware — screens, displays, processing units — is configurable per installation. The operating system underneath remains the same regardless of aircraft type.

Traditional avionics use a federated architecture: each function (flight management, engine monitoring, navigation, autopilot) runs on its own dedicated computer. They communicate over data buses but remain fundamentally separate. Anthem uses an integrated modular avionics (IMA) architecture, centralizing computing power and running functions as software applications on shared processing hardware. This mirrors the approach used in the Airbus A350, but Honeywell is bringing it to much smaller aircraft.

The practical impact: in a federated system, adding a new feature — a better terrain awareness algorithm, a new approach type — often requires hardware changes, a supplemental type certificate, downtime, and significant expense. In Anthem’s software-defined model, many updates can be delivered over the air. Honeywell has stated explicitly that Anthem is designed for OTA software updates, though all updates still require FAA certification before deployment. The certification pathway for software changes is significantly faster than for hardware, potentially months instead of years.

How Does Cloud Connectivity Change Operations?

Anthem was designed from inception to be cloud-connected — not as a retrofit, but as a foundational design assumption. The persistent connectivity enables:

Real-time weather data that isn’t twenty minutes old
In-flight maintenance streaming to operators while the aircraft is airborne
Dynamic flight planning that updates based on current conditions
Predictive maintenance algorithms that learn from an entire fleet, not just one aircraft

The fleet-learning capability is particularly significant for operators. Consider a fleet of twenty air taxis operating in a metro area. If one vehicle develops a subtle vibration signature in a lift motor, the connected architecture streams that data in real time, compares it against the fleet baseline, and flags the anomaly before it escalates into a maintenance event. This is not a future roadmap item — it is the explicit design intent of the platform.

What Levels of Autonomy Does Anthem Support?

Anthem is designed to scale across the full spectrum of pilot involvement:

Conventional two-pilot flight decks with full manual control
Single-pilot operations
Simplified vehicle operations where the pilot manages the mission while the system flies the aircraft
Fully autonomous vehicles with no pilot on board and remote operator monitoring

This scalability matters enormously for certification. The avionics certification process is one of the longest timelines in any new aircraft program. If an eVTOL manufacturer can present the FAA with an avionics suite that already carries a certification pedigree, safety record, and approved architecture, the path to type certification shortens meaningfully.

Who Has Selected Anthem?

These are active aircraft development programs with real certification timelines, not concept studies:

Lilium — selected Anthem for their electric jet
Vertical Aerospace — selected it for the VX4
Pipistrel (Textron eAviation) — working with Honeywell on Anthem integration
Bristow Group — involved in defining requirements for air taxi operations

What’s Different About the Pilot Interface?

Honeywell has departed from the traditional primary flight display / multi-function display layout that has defined glass cockpits since the 1980s. Anthem uses what the company calls a “compact, clean interface philosophy” with an integrated, adaptive presentation.

The displays adjust dynamically based on phase of flight. During takeoff, flight performance data is prioritized. During cruise, emphasis shifts to navigation and weather. During approach, relevant procedure information surfaces automatically. Pilots retain full ability to override and manually configure displays at any time.

Anthem incorporates touchscreen controls alongside physical controls. Critical emergency functions retain dedicated buttons and knobs. Touch is reserved for less time-critical configuration and planning tasks — a pragmatic compromise that addresses the legitimate concern about touchscreen accuracy in turbulence.

What Are the Honest Risks and Unknowns?

Certification is incomplete. As of mid-2025, no Anthem-equipped aircraft has received full type certification. Honeywell has conducted flight testing and extensive bench time, but the eVTOL programs Anthem is tied to are themselves still working through certification. Both Lilium and Vertical Aerospace have experienced timeline shifts.

OTA update governance is still evolving. The FAA’s certification framework for continuous software updates is not yet fully defined. In consumer software, a bug means restarting an app. In aviation, the consequences of an unexpected software interaction are measured in lives. Honeywell is working directly with the FAA on this pathway, but regulatory clarity remains in progress.

Common-mode failure risk. Consolidating diverse aircraft functions onto a single platform trades design-philosophy redundancy for efficiency. In a federated system, a systematic software error in the flight management computer cannot propagate to engine monitoring because the systems are independently designed on separate hardware. Anthem addresses this with multiple layers of dissimilar redundancy, but certification authorities will scrutinize this architectural trade-off closely.

Where Does Anthem Fit in the Broader Avionics Market?

Honeywell is not alone in pursuing platform consolidation. Collins Aerospace has its Perigon system targeting a similar market. Garmin is pushing into autonomy-capable avionics. Thales has its FlytX platform. The avionics industry is undergoing the same kind of platform consolidation the computing industry experienced two decades ago.

The question is no longer whether software-defined, cloud-connected avionics will become the standard. It is which platform wins and how long the transition takes.

For pilots flying certified piston aircraft and light turbines today, Anthem will not appear in your panel soon. It targets new aircraft types and the advanced air mobility market. But the underlying technology decisions — touchscreen interfaces, software update models, adaptive displays — will trickle down. Within a decade, the avionics in a Bonanza or King Air will more closely resemble Anthem than today’s installed systems.
