The Importance of Custom Jetways in Realistic Airport Scenery

Adding custom jetways and passenger boarding bridges transforms a generic airport scenery into a convincing, immersive environment. These structures are among the most visible terminal components—connecting passengers to aircraft at every gate. When modeled with care, custom jetways mirror real-world airport architecture, boost visual fidelity, and elevate the entire simulator experience. Whether you are building for Microsoft Flight Simulator, X‑Plane, or Prepar3D, understanding how to create and integrate custom jetways is a key skill for any serious scenery developer.

Planning and Research Before Modeling

Start by gathering reference material. Study real airport terminal layouts, noting jetway shapes, extension lengths, and connection points. Pay attention to architectural styles—some airports feature glass-walled jetways, others use solid metal tunnels with accordion folds. Visit the airport’s official website or use services like Google Maps satellite view to examine gate areas. Understanding the relationship between terminal building, aircraft type, and jetway height will inform your model’s scale and pivot points.

Essential Tools for the Job

To create custom jetways, you need a combination of 3D modeling software and platform-specific scenery development tools. The following list covers the core toolkit:

  • 3D modeling software – Blender (free, powerful) or SketchUp (intuitive, good for beginners).
  • Texture authoring – Adobe Photoshop, GIMP, or Substance Painter for creating decals, glass reflections, and metal surfaces.
  • Scenery editors – For FSX/P3D, use Airport Design Editor (ADE); for MSFS, use the SDK’s Scenery Editor; for X‑Plane, use WED (WorldEditor).
  • Animation tools – FSX/P3D require XML-based animation scripts; MSFS uses MVAMS or WASM; X‑Plane employs OBJ animation keyframes.
  • Model converter – Tools like ModelConverterX help convert between formats and check for errors.

Each simulator platform imposes specific polygon and texture limits. Plan your model’s level of detail (LOD) accordingly to maintain performance.

Designing the Jetway Model

Understanding Jetway Anatomy

A typical jetway consists of a fixed section (attached to the terminal), a telescoping tunnel (extends or retracts), and a cabunit (the rotunda at the aircraft end). Many models also include a glass walkway, a canopy, and moving handrails. The tunnel often uses a series of overlapping panels to simulate the accordion folds. For custom work, you can simplify this into a few textured polygons or model each fold individually for higher fidelity.

Modeling the Basic Structure in Blender

Start with a reference object—a simple cylinder or box—to establish the correct height and width. Typical tunnel dimensions are about 3 m wide, 2.5 m high, and up to 30 m in length. Use edge loops and extrusion to create the accordion folds. Apply a lattice modifier if you want to curve the tunnel to match a terminal walkway. For the cab, model a hexagonal or octagonal prism, then add a glass dome with a transparent material.

Pay attention to the pivot point of each animated part. The tunnel must rotate and translate relative to the terminal; the cab must rotate to align with the aircraft door. In Blender, set the origin (Ctrl+Shift+Alt+C) to the attachment point before exporting.

Texturing for Realism

Use physically‑based rendering (PBR) textures wherever possible. Create a metal base with rust or dirt details using roughness maps. Glass needs transparency and a slight reflection; enable alpha blending in your material. Add decals with airline logos or ground service text to increase authenticity. Keep texture sizes reasonable—2048² per main part is often sufficient for jetways in a typical airport.

For the accordion folds, a tiled texture of overlapping metal sheets works well. Use a normal map to give the folds depth without additional geometry.

Importing and Positioning the Model in Your Scenery

Exporting and File Format

Export your model in the simulator’s native format. For FSX/P3D, that is .MDL (via the X file format or P3D SDK); for MSFS, export as .glTF; for X‑Plane, use .OBJ format. Always include the texture files in the correct folder structure. Use a tool like ModelConverterX or the MSFS Sample Tool to check for material and UV errors.

Placement in the Scenery Editor

Open your scenery editor and load the airport. Locate the gate where the jetway will be placed. Add an object or library object and point to your exported model. Position the jetway so the fixed end attaches to the terminal wall and the cab sits correctly in the gate center. Most editors allow you to adjust pitch, roll, and heading. Test alignment by parking an aircraft model at the gate.

In ADE or WED, you can create a jetway placement that includes a parking spot. The software will automatically align the jetway with the aircraft door. Refer to the official MSFS Scenery Documentation for detailed instructions on aircraft parking radii and jetway links.

Adjusting for Different Aircraft Types

No single jetway fits all aircraft. Design your model to allow some universal adjustment—either by scaling the tunnel length or by creating multiple LOD versions. In the scenery editor, you can set the jetway type (e.g., “long” for widebodies, “short” for narrowbodies). Some advanced setups use an animation that automatically extends the tunnel when an aircraft parks. This requires scripting, which we cover next.

Adding Animations and Interactivity

Static vs. Dynamic Jetways

A static jetway is a simple model that does not move. It suffices for background scenery but looks unnatural when an aircraft parks. Dynamic jetways—those that rotate, extend, or have moving passenger doors—add a professional touch. The complexity ranges from a simple cab rotation to fully scripted extend/retract sequences.

Animation Techniques by Platform

FSX/P3D: Use XML gauge animation. Create an XML file with keyframes that translate/rotate the appropriate parts. Attach this animation to the model via the sim’s animation system. Example: a 100‑frame animation where the tunnel scales along its Z‑axis to simulate extension.

MSFS: Use the MVAMS or HTML/JS based animation system. The SDK provides “Behavior” files that allow you to define how the object responds to user interaction or parking events. SimConnect variables can drive door opening, cab rotation, and tunnel movement.

X‑Plane: Attach anim_begin/anim_end keyframes in the OBJ file. Use datarefs such as sim/aircraft/parts/acf_gear_deploy to trigger movement. More advanced implementations use SASL or FlyWithLua scripts.

For all platforms, ensure the animation speed is realistic—a full extend sequence should take about 8–15 seconds, matching real‑world operation.

Testing and Fine‑Tuning

After scripting, test with a variety of aircraft. Common issues: the cab does not rotate enough, the tunnel collides with the aircraft, or the textures flicker during animation. Adjust animation keyframes and check that all moving parts have proper collision (if your sim supports it). Use the developer console (MSFS) or log files (X‑Plane) to debug.

Passenger Boarding Bridges: Differences and Advanced Options

Passenger boarding bridges (PBBs) are essentially the same as jetways but often include additional features like moving walkways, glass walls, and HVAC connections. For scenery, you may want to replicate specific bridge types: apron‑drive bridges (the cab moves on wheels), fixed bridges (stationary), or nose‑loaders (some regional airports).

Modeling the moving apron – An apron‑drive bridge has a support structure on wheels that drives out from the terminal. Model these wheels and attach suspension as a separate object. For realism, add a decal of the airline’s ground power unit.

Integration with ground service vehicles – Advanced scenery can link the bridge position to the appearance of stair trucks, baggage carts, and fuel trucks. Use scenery object triggers or SimConnect to spawn vehicles when an aircraft parks.

For inspiration, study the default jetways provided with MSFS or the freeware bridges available on Flightsim.to. Many authors share their model files; you can modify them under license terms.

Optimizing for Performance

Multiple jetways at a busy airport can drag down frame rates if not optimized. Follow these guidelines:

  • Polygon count – Keep each jetway under 2000 triangles. Use normal maps for detail instead of geometry.
  • Texture atlasing – Combine several textures into a single sheet to reduce draw calls. Place the terminal, jetway, and ground markings on the same atlas.
  • LODs – Create three LOD levels. At a distance, the jetway can become a solid box with a flat texture. The closest LOD should have full animation and glass transparency.
  • Batching – In the scenery editor, use grouping or layer functions to merge jetways with terminal buildings when the sim allows.
  • Dynamic lighting – Avoid real‑time lights on moving parts. Bake ambient occlusion and reflection onto the texture.

Putting It All Together: A Workflow Summary

  1. Collect references and plan your jetway dimensions.
  2. Model the fixed tunnel, moving tunnel, cab, and any extras in Blender.
  3. UV‑unwrap and texture with PBR materials.
  4. Set origins for all animated child objects.
  5. Export to the required simulator format (MDL, glTF, OBJ).
  6. Import into the scenery editor and position at the gate.
  7. Add animation scripts (XML, Behavior, OBJ keyframes) for dynamic movement.
  8. Test with multiple aircraft types and fine‑tune.
  9. Optimize LODs, texture budgets, and draw calls.
  10. Package scenery according to your simulator’s distribution guidelines.

With practice, you can produce jetways that look indistinguishable from the real thing. The investment in time pays off when users walk a virtual passenger through a gate that mirrors a real airport.

Further Resources and Next Steps

For deep documentation, consult the official SDKs: MSFS SDK documentation covers animation and scenery object behavior. The FSDeveloper forum has a wealth of user‑shared scripts and model files. For Blender‑specific tutorials, search for “Blender low‑poly jetway tutorial” on YouTube.

Custom jetways breathe life into airport scenery. By mastering modeling, texturing, animation, and optimization, you can create walkable, realistic terminals that enhance every flight. Start with a single gate, then expand to build your own custom airport from the ground up.
