Mixed Reality in Aircraft Cabin Design: A Deep Dive into Aerosimulations’ Approach

The aerospace industry is under constant pressure to deliver superior passenger experiences while maintaining operational efficiency. For companies like Aerosimulations, a leader in advanced aerospace simulation and design, the passenger cabin has become a key differentiator. However, planning and optimizing cabin layouts has historically been a difficult, iterative process—one that relies on 2D drawings, physical mock-ups, and late-stage changes that inflate costs. To address these challenges, Aerosimulations has turned to mixed reality (MR) tools, blending digital and physical worlds to transform how cabins are envisioned, tested, and refined.

Mixed reality sits between augmented reality (AR) and virtual reality (VR). While VR immerses users entirely in a digital environment and AR overlays digital content onto the real world, MR allows digital objects to interact with physical space in real time. For cabin layout planning, this means engineers can place a virtual seat, galley, or lavatory into an actual workshop or aircraft shell and assess its fit, ergonomics, and aesthetic impact from every angle. This technology is more than a visualization gimmick—it is a practical tool that reduces risk, accelerates decision-making, and fosters collaboration across geographically dispersed teams.

In this article, we explore how Aerosimulations has implemented MR tools for passenger cabin layout planning, the tangible benefits they have realized, the technical workflow behind the scenes, and what the future holds as MR matures alongside AI and machine learning.

The Challenges of Traditional Cabin Layout Planning

Before MR, Aerosimulations relied on a combination of computer-aided design (CAD) models, physical mock-ups, and 2D engineering drawings. Each of these methods had significant limitations. CAD models displayed beautifully on a monitor but failed to convey the sense of scale, depth, and movement within a cabin. Designers could rotate a 3D model on screen, but they could not walk through it, sit in a virtual seat, or test how sunlight would fall across a row of headrests at a specific time of day.

Physical mock-ups, while valuable for tactile evaluation, are expensive and time-consuming to build. A single first-class seat layout might require weeks of carpentry, upholstery, and lighting installation. Any change—shifting a partition by a few inches, swapping a seat width, or altering the angle of a bulkhead—demands rebuilding or reconfiguring the mock-up, leading to cascading delays. Moreover, mock-ups are typically static; they cannot simulate dynamic scenarios such as emergency evacuation flows or the movement of service trolleys down an aisle.

Another pain point is cross-team collaboration. Aircraft cabin design involves not just interior designers and engineers, but also marketing executives, airline customers, safety regulators, and maintenance personnel. Scheduling a time for all stakeholders to visit a physical mock-up is logistically difficult, especially when teams are spread across continents. Even when they do gather, it is nearly impossible to iterate on multiple layout options in a single session.

Aerosimulations recognized that a new approach was needed—one that could bridge the gap between digital precision and physical intuition without the cost and latency of physical prototyping.

What Is Mixed Reality in the Context of Cabin Design?

Mixed reality merges real and virtual worlds to produce new environments where physical and digital objects coexist and interact in real time. Unlike augmented reality, which merely superimposes images onto a user’s field of view, MR enables depth occlusion, spatial mapping, and physics-based interaction. A virtual chair placed in a real workshop will appear to rest on the actual floor, cast virtual shadows, and can even respond to a user’s hand gestures as if it were a tangible object.

In cabin layout planning, MR allows designers to:

  • Spawn and arrange virtual seats, galleys, lavatories, and monuments within a physical room that represents the aircraft cross-section.
  • Walk around and through the virtual cabin, crouching to examine storage bins or standing to assess overhead clearance.
  • Change materials, colors, and lighting instantaneously to evaluate different aesthetic schemes.
  • Animate service flows, such as a flight attendant navigating a trolley down the aisle, to confirm ergonomic efficiency.
  • Capture and share annotations directly in the 3D space, creating a persistent record of design decisions.

This is a fundamental shift from viewing a cabin on a flat screen to inhabiting it. The result is a much deeper understanding of spatial relationships and passenger experience before any metal is cut.

Why Aerosimulations Chose MR Over VR or AR Alone

While VR offers total immersion, it also isolates the user from their physical surroundings. In a VR headset, a designer cannot see their own hands, a colleague, or the real tools on the workbench. This can be disorienting and impractical for collaborative reviews where someone might want to point to a physical object or reference a printed document. AR, on the other hand, lacks the depth and occlusion necessary for precise spatial judgment—digital objects appear to float rather than anchor to real surfaces.

MR provides the best of both worlds: the user remains aware of their physical environment while digital assets are seamlessly integrated with realistic depth and occlusion. For Aerosimulations, this meant that engineers could work side by side with airline representatives, pointing to real parts of a cabin mock-up while simultaneously viewing virtual modifications projected into that same space. This hybrid environment accelerated consensus and reduced misinterpretation.

Furthermore, MR devices like Microsoft HoloLens 2 and Varjo XR combine inside-out tracking with high-fidelity hand and eye tracking. Users can grab, resize, and rotate virtual objects naturally, without needing a controller. This intuitive interaction model lowered the learning curve for stakeholders unfamiliar with CAD software, allowing executives and airline buyers to participate directly in the design review.

Benefits Realized at Aerosimulations

Enhanced Visualization and Spatial Understanding

The most immediate benefit was a dramatic improvement in how stakeholders perceived cabin space. Instead of trying to imagine how a 2D floor plan would feel, they could walk through the cabin at scale, noting headroom, legroom, and the line of sight from various seats. This immersive experience uncovered issues that would have been missed in a computer model, such as a passenger’s view being partially blocked by a misplaced overhead bin or an aisle width that felt tight when two people passed.

Faster Iteration and Reduced Development Time

In traditional workflows, making a change to a cabin layout required updating the CAD model, generating new renderings, and possibly modifying a physical mock-up. With MR, adjustments can be made in real time during a review session. A designer can drag a seat three inches forward, swap the upholstery color from gray to blue, and change the galley configuration—all while the airline customer watches. The iterative loop shrank from days to minutes. According to internal reports, Aerosimulations reduced the number of design revision cycles by nearly 40% on MR-assisted projects.

Cost Savings Through Early Issue Detection

Fixing a design flaw in the digital stage costs a fraction of what it costs after tooling begins. For example, during one early MR review, a maintenance engineer noticed that a lavatory door would interfere with the opening of an adjacent overhead bin. In a conventional process, this issue might only have been discovered during a physical fit check, forcing costly rework of the lavatory module and the bin assembly. Because it was caught in MR, the team simply repositioned the lavatory, checked for clearances, and moved on—saving an estimated $50,000 and three weeks of delay.

Better Cross-Disciplinary Collaboration

MR sessions at Aerosimulations frequently included participants from engineering, industrial design, marketing, customer support, and even representatives from the airline’s in-flight service team. Each group brought different priorities. The MR environment allowed them to overlay annotations, measure constraints, and test “what-if” scenarios on the spot. Remote participants could join via a shared MR session, viewing the same virtual cabin and interacting with the same objects, even if they were in different cities. This level of collaboration was previously impossible without everyone traveling to a central location.

Implementation Workflow: From CAD to Mixed Reality

Aerosimulations developed a streamlined workflow to bring cabin designs into MR. The process begins with detailed 3D modeling in CAD software such as Autodesk’s 3D CAD tools. Engineers create precise geometry for every cabin component, including seats, galleys, lavatories, overhead bins, partitions, and lighting. The models include surface finishes, textures, and even fabric simulations for seat covers.

Next, the CAD data is exported to a format compatible with the MR platform. Aerosimulations primarily uses Unity or Unreal Engine to render the models, taking advantage of their real-time lighting and physics engines. Custom scripts are written to handle interaction logic—for example, allowing a user to open a virtual bin door and see how much space it consumes in the aisle.

The processed scene is then deployed to the MR headset. Aerosimulations standardizes on Microsoft HoloLens 2 for its comfortable form factor and robust spatial mapping, and Varjo XR-3 for high-fidelity visual reviews that require ultra-realistic rendering. The headset scans the physical room, creating a mesh of the surfaces. The virtual cabin is then anchored to that mesh, so the digital seats appear to rest on the real floor and the virtual walls align with the physical room’s dimensions.

During review sessions, facilitators use a tablet or voice commands to load different layout configurations, adjust lighting conditions (simulating dawn, midday, or dusk), and toggle between material options. All changes are recorded, and screenshots or video clips can be captured for documentation. The entire session can be streamed to remote observers who view the mixed reality scene on their monitors or through their own headsets.

Case Studies: MR in Action at Aerosimulations

Wide-Body Cabin Reconfiguration

One of Aerosimulations’ major projects involved redesigning the premium economy section of a long-haul wide-body aircraft. The airline wanted to increase seat count without sacrificing passenger comfort—a classic trade-off. An MR review session with the airline’s cabin product team allowed Aerosimulations to test four different seat pitches and three different seat widths in rapid succession. The team walked through each configuration, sitting in virtual seats and measuring personal space. They discovered that a subtle change in the seat back curvature could compensate for a slight reduction in pitch, maintaining comfort while adding 12 seats. The decision was made in a single day, whereas traditional mock-up evaluations would have taken weeks.

Accessibility Compliance Check

Regulatory compliance, especially for passengers with reduced mobility, is a critical aspect of cabin design. Aerosimulations used MR to simulate a wheelchair user navigating the cabin. The designer could adjust the width of cross-aisles, test the reach to overhead bin handles, and ensure that lavatory doors had adequate turning radius. Because the MR program allowed the user to set their own eye height and reach, they could evaluate the design from the perspective of a person in a wheelchair. This led to several design changes that made the cabin more inclusive, and the airline’s compliance team approved the layout without requiring a physical fitting.

Technical Considerations and Challenges

Despite the benefits, implementing MR for cabin planning was not without obstacles. Aerosimulations had to address several technical and operational challenges.

Rendering Fidelity and Performance

Cabin models are complex, often containing hundreds of thousands of polygons. Running such scenes on a head-mounted display requires a delicate balance between visual quality and frame rate. A drop below 60 frames per second can induce discomfort and break the sense of presence. Aerosimulations optimized their models by using level-of-detail techniques and baked lighting where possible. For the highest fidelity reviews, they employed a tethered setup with a powerful workstation driving the headset, ensuring smooth performance.

Physical Space Constraints

MR works best when the physical space matches the virtual cabin dimensions. For a narrow-body aircraft, a typical workshop might suffice. For a wide-body cabin, the physical room needs to be large enough to host a full-length fuselage segment. Aerosimulations invested in a dedicated MR studio with an open floor plan and high ceilings, allowing users to walk the entire length of a virtual cabin. They also developed a “teleportation” navigation system for reviews where the physical space was smaller than the virtual environment.

User Training and Adoption

Not all stakeholders are comfortable with head-mounted displays. Some experienced motion sickness, especially when moving quickly through the virtual cabin. Aerosimulations implemented a gradual onboarding process: first showing static overlays, then allowing slow walking, and finally enabling full locomotion options like “blink” teleportation to reduce nausea. They also provided MR viewing stations with large monitors for those who preferred not to wear a headset but still wanted to participate in the session.

The Role of AI and Machine Learning in Future MR Workflows

Looking ahead, Aerosimulations is planning to integrate artificial intelligence and machine learning into their MR pipeline. The goal is to move from being purely a visualization and review tool to a generative design assistant. For instance, an AI trained on thousands of cabin layouts could suggest optimal seat arrangements based on passenger flow data, emergency egress requirements, and airline preferences. The designer could accept, modify, or reject these suggestions in the same MR environment.

Machine learning could also enhance real-time ergonomic analysis. By tracking user movements within the virtual cabin, the system could detect when a seat is too close to a service door or when a reachable storage bin is out of range for 95% of passengers. Aerosimulations is experimenting with AI-powered annotations that automatically flag potential compliance violations as the user interacts with the virtual cabin.

Another promising area is voice and gesture commands driven by natural language processing. Instead of using a tablet to navigate menus, a designer might say, “Show me the emergency exit path for a 300-passenger configuration,” and the MR system would instantly animate the evacuation flow. Aerosimulations is collaborating with Microsoft to leverage HoloLens’ Azure Kinect for hand tracking and voice recognition.

Comparing MR with Other Visualization Techniques at Aerosimulations

Beyond MR, Aerosimulations also employs AR and VR for specific use cases. AR is used for on-the-fly overlay information during physical mock-up testing—for example, displaying heat maps of cabin temperature or noise levels overlaid on real seats. VR is reserved for full-immersion scenarios that require complete focus, such as simulating a passenger experiencing the entire boarding process from the jet bridge to the seat. However, for the core task of collaborative cabin layout planning, MR proved to be the most versatile.

The cost of MR headsets has also decreased significantly. A HoloLens 2 unit costs around $3,500, which is a fraction of the cost of a single physical mock-up seat module. When factoring in travel costs avoided and design cycle time saved, Aerosimulations achieved a return on investment within six months of deploying MR into their standard workflow.

External Resources and Continuous Learning

To stay at the forefront of MR technology, Aerosimulations regularly consults industry resources such as:

The company also participates in conferences like the Aerospace Innovation Summit to exchange best practices with other manufacturers.

The Future of Cabin Design at Aerosimulations

Mixed reality has moved from an experimental novelty to a core component of Aerosimulations’ cabin layout planning process. The company intends to extend MR usage into other areas, including crew rest compartment design, cargo hold optimization, and even maintenance training. They are also exploring the use of haptic gloves to give users the sensation of touching different seat materials or feeling the resistance of a door latch—adding a tactile dimension to the virtual experience.

As 5G and edge computing mature, Aerosimulations expects to offload heavy rendering to cloud servers, enabling lighter MR headsets with longer battery life. This would allow field representatives to use MR during on-site meetings at airline offices, where they could pull up a full cabin configuration on a simple pair of smart glasses.

Ultimately, the integration of MR with AI-driven analytics will create a feedback loop: each design session generates data on what works and what doesn’t, training the AI to make smarter suggestions. The result will be cabins that are not only optimized for space and cost but also more comfortable, accessible, and pleasing to passengers. Aerosimulations is proving that mixed reality is not just a tool for visualization—it is a platform for innovation that reshapes how we think about the aircraft interior.
