Introduction to Terrain and Airport Editing in AeroSimulations

Creating immersive flight simulation environments requires more than just accurate aircraft physics. The terrain beneath your wings and the airports you depart from or arrive at must feel realistic to complete the experience. AeroSimulations provides a powerful set of terrain and airport editing tools that let you shape landscapes, design functional runways, and add the intricate details that make a virtual world come alive. Whether you’re building a small airstrip for bush flying or a major international hub, this guide will walk you through every essential tool and technique.

The editing suite is designed for both newcomers and seasoned simmers. If you’ve never modified a terrain mesh or placed a taxiway before, don’t worry—the workflow is intuitive once you understand the interface and core concepts. We’ll cover everything from initial setup to advanced customization, including common pitfalls and how to avoid them. By the end of this article you’ll have the confidence to craft custom landscapes and airport layouts that rival professional add‑on scenery.

Note: All instructions assume you are using the latest version of AeroSimulations. Always check for updates before starting a new project, as tool sets and user interface elements occasionally change. For official updates, visit the AeroSimulations website.

Getting Started with AeroSimulations Editing Environment

Launch AeroSimulations and open the editing mode from the main menu. You’ll see the standard flight simulation interface transform into a workspace populated with toolbars, a layers panel, and a 3D viewport. Take a few minutes to explore the layout:

  • Toolbar – Contains icons for terrain editing, airport placement, object selection, and general navigation.
  • Layers Panel – Manages different data overlays such as elevation data, satellite imagery, and airport markings. Understanding layers is key to non‑destructive editing.
  • Properties Panel – Shows dimensions, elevations, and attributes of the currently selected element. You can edit precise values here.
  • Viewport Controls – Zoom, pan, and rotate the camera freely. Use the mouse wheel and middle button for quick navigation.

Before making any changes, set up a project folder. AeroSimulations uses a file‑based approach: your terrain modifications are stored in a dedicated project file (.aep or similar), separate from the base simulator data. This keeps your work safe and modular. Load a base map of the region you want to edit—either an existing global terrain mesh or a flat area to start from scratch. For best results, enable the “High‑Resolution Elevation Data” option if available; it provides more detailed heightmaps for fine‑grained editing.

Using the Terrain Editing Tools

The terrain editor lets you sculpt the ground surface with brush‑based tools. Think of it like working with digital clay: you can raise, lower, flatten, or smooth the land to create hills, valleys, plateaus, and riverbeds. Here’s a detailed breakdown of the primary tools.

Selecting and Configuring the Terrain Brush

Click the Terrain icon (usually a mountain shape) on the toolbar. A circular brush appears in the viewport. Use the Brush Size slider to adjust the diameter from a few meters to several hundred meters. The Intensity slider controls how much elevation change occurs with each click‑and‑drag. For gentle slopes, use low intensity (10–20%). For dramatic cliffs or sudden drops, bump it up to 50% or more. You can also choose a brush falloff curve—soft edges create natural blending, while hard edges are useful for man‑made features like quarry walls or terraces.

Hold the left mouse button and drag upward to raise terrain, or hold the left button and drag downward (or use the “Lower” mode) to dig. The change is applied in real time. For precise modifications, switch to the Height Lock mode: set a target elevation (in meters above sea level) and the brush will push the terrain exactly to that height.

Advanced Terrain Manipulation

Beyond simple raising and lowering, the editor includes specialized tools:

  • Flatten – Levels an area to the average height under the brush. Ideal for constructing runway platforms or building pads.
  • Smooth – Removes jagged edges by averaging heights with neighboring points. Use this after major sculpting to eliminate step‑like artifacts.
  • Noise – Adds random small‑scale variation to create realistic surface roughness (e.g., rocky ground, field furrows). Adjust the noise scale and magnitude to match your environment.
  • Erosion Simulator – A powerful tool that mimics natural water erosion. It generates gullies, ridges, and sediment deposits, giving your terrain a weathered appearance. Run it on a selected area with controlled iterations (2–5 passes usually work well).

Combine multiple tools in stages. For example, start by raising a mountain ridge with a large brush, then use the Noise tool to add texture, and finish with the Smooth brush on the peaks for a softer profile. For an in‑depth look at terrain generation algorithms, refer to this survey on procedural terrain techniques (external, but the concepts apply).

Working with Elevation Data Layers

AeroSimulations can import real‑world elevation data (GeoTIFF or SRTM files). This is invaluable for recreating actual landscapes. Place the data file in your project’s “Elevation” layer and the terrain will automatically morph to match the heights. You can then manually tweak the result, adding custom structures like airports or canals. To integrate orthophoto imagery, load a satellite or aerial photo into the “Texture” layer—this gives you visual reference while editing.

Be mindful of performance: high‑resolution elevation data with millions of vertices can slow down the editor. Use the “Level of Detail” (LOD) settings to preview at lower resolution during editing and switch to full resolution for final rendering.

Tips for Realistic Terrain

  • Study topographic maps of the region you’re recreating. Note ratios of slope angles—most natural landscapes have slopes under 30 degrees.
  • Add micro‑variations: a completely flat area looks artificial. Use the Noise tool lightly over fields and meadows.
  • Create water bodies by lowering an area below the water plane altitude. Place a “Water” mask to enable reflections and wave animations.
  • Always save incremental versions (e.g., terrain_v1, terrain_v2). If you make a mistake later, you can revert without losing all progress.
  • Use the Undo (Ctrl+Z) frequently. The undo history is generous, but it is cleared when you close the editor—so save before quitting.

Editing Airport Layouts

Airports in AeroSimulations are constructed from runway, taxiway, apron, and terminal objects. Each element has its own physical properties and must be placed with attention to real‑world standards. The following steps guide you through creating a functional and visually appealing airport.

Planning Your Airport Layout

Before placing any objects, sketch a rough plan. Decide the number of runways, their orientation (runway numbers based on magnetic heading), taxiway paths, and the location of the terminal. Consider prevailing wind directions—real airports align runways with the most frequent winds. Use an online tool like SkyVector airport database to study real‑world airport diagrams. This will help you place elements logically.

Adding Runways

Click the Airport icon on the toolbar (often a runway symbol). Select Add Runway from the dropdown menu. Click on the map to set the start point, then drag to define the direction and length. A runways is defined by:

  • Length – Set in meters or feet via the Properties panel.
  • Width – Standard widths vary: 30 m for small general aviation, 45 m for commercial, up to 60 m for major international.
  • Surface Type – Asphalt, concrete, grass, gravel. This affects friction and aircraft performance in the sim.
  • Threshold Lights – Enable approach lighting systems (ALS) and PAPI (Precision Approach Path Indicator) for realism.
  • Runway Number – AeroSimulations auto‑calculates based on heading, but you can override it (e.g., 13/31).

Once placed, you can move the entire runway by selecting it and dragging, or adjust its endpoints individually. Use the Align to Terrain option to make the runway follow the ground slope—but for safety, you usually want the runway to be flat. You can flatten the underlying terrain using the Flatten brush around the runway area before placing it.

Building Taxiways and Aprons

Taxiways connect runways to parking stands. Select Add Taxiway and click‑and‑drag a path. Taxiways have a width (typically 15–23 m) and a surface type. You can add nodes to change direction—each node is a control point; drag to create curves. For complex layouts, use the Offset Tool to mirror a taxiway for parallel lanes (e.g., taxiways A and B).

Aprons are large paved areas for aircraft parking. Draw them as polygons using the Add Apron tool. Click to place vertices, then double‑click to close the shape. In the Properties panel, define the surface material and marking style (e.g., tie‑down lines for GA, gate markings for airliners). Aprons can be precisely snapped to taxiway edges using the Snap to Vertex mode.

Placing Terminal Buildings, Hangars, and Objects

AeroSimulations includes a library of static objects: terminals, hangars, jetways, fuel trucks, windsocks, lighting poles, and more. To place them:

  1. Switch to the Object Mode (cube icon).
  2. Select a category from the library browser (e.g., “Buildings” → “Terminal”).
  3. Click on the apron or near the runway to position the object. You can rotate it with the rotation tool (R key) and scale it (S key) if needed.
  4. Use the Height Offset option to raise the object above the ground (e.g., for a tower cabin).

For advanced customization, you can import your own 3D models in .glTF or .fbx format. Ensure they are properly scaled and textured before importing. Official documentation for model import can be found on the AeroSimulations developer portal.

Connecting Everything Taxiway Network Routing

After placing runways, taxiways, and aprons, you must connect them into a logical network so that AI aircraft can navigate. AeroSimulations uses a node‑based routing system:

  1. Enable Show Taxiway Nodes from the layers panel.
  2. Select the Connect Tool.
  3. Click on a taxiway node, then click on an adjacent node or a runway endpoint. A green line appears, indicating a valid connection.
  4. Set node restrictions: you can specify “runway hold short” points, “no entry” for certain aircraft, or speed limits.
  5. Test the network by spawning an AI aircraft at a parking spot and observing if it can taxi to the runway without hitting objects.

Poorly connected nodes cause AI to stop abruptly or take impossible paths. Spend time laying out nodes meticulously—this separates amateur sceneries from professional once. The community routing tutorial (external) provides additional insights.

Refining and Detailing Your Airport

With the basic layout complete, focus on the details that make your airport unique. Lighting is critical for night operations: add edge lights for runways, taxiway centerline lights, and apron floodlights. Markings like runway thresholds, centerlines, and taxiway hold‑short lines can be painted using the Marking Tool—choose from a library of stencils and apply them to the surface.

Vegetation and ground clutter add realism. Use the Vegetation Painter to scatter trees, bushes, and grass around the airport perimeter. Control density with the brush settings. For urban airports, add nearby buildings and roads using the general object library or custom models.

Don’t forget the environment: set the airport’s elevation correctly (check real‑world data). Adjust the local magnetic declination so that runway headings match real compass headings. You can find this value from sources like NOAA’s magnetic field calculator.

Final Tips and Best Practices

  • Save Incrementally – Use version numbers in your filename. After major milestones (e.g., terrain complete, runway placed, taxiways connected), save a new version.
  • Back Up Your Project – Keep a copy on an external drive or cloud storage. Some users have lost hours of work due to hard drive failure.
  • Test in the Simulator – Periodically load your project into AeroSimulations flight mode. Check for visual glitches, misplaced objects, or AI path issues. The editor view can be misleading.
  • Join the Community – The AeroSimulations forum and Discord are active with modders and scenery designers. Share your work, ask for feedback, and learn from experienced creators.
  • Performance Optimization – Keep polygon counts reasonable. Use LOD models for distant objects. Avoid placing hundreds of individual trees when a single forest object can cover the same area.
  • Learn from Mistakes – Every scenery designer creates something that looks odd at first. Undo, tweak, and iterate. Patience is your greatest tool.

Conclusion

Mastering the terrain and airport editing tools in AeroSimulations opens up a world of creative possibilities. You can fly into your hometown airport accurately recreated, build a fictional alpine airstrip surrounded by custom‑sculpted peaks, or even replicate famous airfields from history. The step‑by‑step methods outlined here—from brushing the earth to routing taxiway networks—give you a solid foundation to start building.

Remember that great sceneries are built layer by layer. Start with a small project, such as modifying a single runway and its adjacent parking area, before tackling a full international airport. Each project will teach you more about the tools’ nuances. Keep the official documentation bookmarked, experiment freely, and always save your work.
