Getting Started with AeroSimulations Terrain Add-Ons

Before you begin crafting scenic VFR tours, ensure you have the necessary AeroSimulations terrain products installed. These add-ons deliver highly detailed elevation meshes, landclass data, and custom vector elements that transform default Prepar3D scenery. Visit the AeroSimulations official website to browse available regions—from the rugged Pacific Northwest to the Alps or the Australian outback. Each package typically requires Prepar3D v4 or v5 and adequate system resources to run high-detail textures.

After installation, verify that the terrain is properly activated via Prepar3D’s Scenery Library. Open Options → Add-ons and confirm the AeroSimulations entries are checked. For best performance, set a high terrain mesh resolution (e.g., 5m) in the World tab of Prepar3D’s Settings. This ensures that cliffs, valleys, and urban structures appear with maximum fidelity.

Selecting a Region for Your Scenic VFR Tour

The foundation of any memorable VFR flight is the region itself. Choose an area that offers dramatic elevation changes, water bodies, forested ridges, or distinctive man-made landmarks. AeroSimulations’ product line covers diverse landscapes; pick one that aligns with your visual interests. For instance:

  • Coastal mountain ranges – ideal for low-level passes through fjords or along ridgelines.
  • Desert canyons – provide stark contrast and sharp contours.
  • Urban corridors – allow you to fly over city skylines with realistic building shapes.
  • Agricultural valleys – showcase patchwork fields and winding rivers.

Once you’ve selected a region, open the AeroSimulations terrain editor (if supplied) or use the free Prepar3D SDK to inspect the area. Study the contour lines, landclass zones, and custom landmarks. Note any airports or airstrips you can use as start/end points.

Understanding AeroSimulations’ Terrain Features

AeroSimulations’ products go beyond generic elevation data. They incorporate photorealistic textures, custom autogen definitions, and manually placed object libraries. Key features include:

  • High-resolution elevation meshes that reveal ravines, rock formations, and hillcrests with sub-meter accuracy.
  • Detailed landclass that distinguishes between coniferous forest, deciduous woods, grassland, scrub, and bare rock – each with its own seasonal variation.
  • Water bodies with realistic shorelines, reflections, and transparency levels.
  • Vector data for roads, railroads, power lines, and even field boundaries that follow actual survey maps.
  • Custom airports – many regions include hand-crafted airfields with accurate runway markings and buildings.

These layers can be combined using Prepar3D’s terrain engine. When planning a VFR route, think of each feature as a visual cue: a meandering river becomes a navigation reference; a distinct mountain peak marks a waypoint.

Planning Your Scenic Flight Route

Using Prepar3D’s Flight Planner

Launch Prepar3D and open the Flight Planner from the World menu. Choose your starting airport and destination. Then add intermediate waypoints by double-clicking on the map. For maximum scenery appreciation, avoid direct great-circle lines; instead, zigzag between landmarks. Keep the total flight time to 1–2 hours at a typical GA cruise speed (100–150 knots) so you can absorb details.

Incorporating Landmarks as Waypoints

Identify three to five major geographic features per leg:

  • Mountaineous ridges or unique peaks (e.g., Mount Whitney in California, the Matterhorn in the Alps).
  • Lakes with irregular shorelines.
  • Large river bends or confluence points.
  • Densely built-up city centers or distinct industrial complexes.
  • Coastal inlets, peninsulas, or arches.

Use the AeroSimulations terrain editor to pinpoint exact coordinates. Alternatively, use Google Earth to locate features, then note their latitude/longitude for entry into Prepar3D’s planner.

Setting Safe Altitudes

VFR routes must respect terrain elevation. Use AeroSimulations’ elevation profiles to identify high points. Plan to fly at least 500 feet above the highest obstacle within 2 nautical miles of your intended route. For mountainous regions, consider a buffer of 1,000 feet. Prepar3D’s altitude warnings (from the Options → Realism menu) can be set to alert you when approaching terrain.

Configuring AeroSimulations for Optimal Visual Quality

To fully leverage the terrain detail, adjust these settings in Prepar3D’s Graphics menu:

  • Terrain LOD (Level of Detail) Radius: Increase to at least “High” or “Ultra” to maintain sharp textures at a distance.
  • Mesh Resolution: Set to 5m or 2m if your system can handle it.
  • Texture Resolution: 1024×1024 or higher for landclass tiles.
  • Water Detail: Choose “Ultra” to see reflections of mountains and clouds.
  • Scenery Complexity: “Extremely Dense” for full autogen buildings and vegetation.

Also configure the AeroSimulations-specific control panel (if available). Here you might enable seasonal textures, high-resolution road textures, and custom object density. Restart Prepar3D after changes so the mesh cache rebuilds.

Aircraft Selection for Scenic VFR Flying

Choose an aircraft that offers good visibility and slow flight capability. Popular choices include:

  • Piper Cub or Aviat Husky – high-wing, stable, and can fly below 60 knots.
  • Diamond DA40 or Cessna 172 – common training aircraft with panoramic windows.
  • Maule M-7 – robust STOL performance enables low-altitude passes.
  • Bell 206 JetRanger – helicopter for vertical freedom and unique viewpoints.

Ensure you have a good head tracker (TrackIR) or use a hat switch to look around. Many flightsimmers also benefit from a free camera add-on such as ChasePlane or EZDok for cinematic views.

Weather and Time-of-Day Considerations

Weather dramatically affects scenery visibility. Ideal VFR conditions are:

  • Clear skies or few cirrus clouds (CAVOK).
  • Visibility of 10+ miles.
  • Light winds to avoid turbulence in valleys.

Use a real-time weather engine like Active Sky for dynamic conditions, but manually set the date/time to catch the “golden hours” of sunrise or sunset. Low-angled sunlight creates long shadows that emphasize terrain contours. Golden hour flights also produce striking screenshots and videos.

Tip: Use Time Lapse acceleration (via Prepar3D’s menu) to transition from dawn to full daylight in minutes, showcasing how terrain colors change.

Executing the Scenic VFR Flight

Load your planned flight and perform a standard pre-flight check. As you depart, climb to your planned cruising altitude while scanning the horizon for your first waypoint. Keep the aircraft trimmed for hands-off flight so you can look around. Use the VOR/GPS to confirm your position but prioritize visual references: a lake shape, a mountain silhouette, or a specific road intersection.

When approaching a landmark, reduce throttle and lower altitude (if safe) to pass close – but not too close – to the feature. For instance, fly parallel to a canyon rim at 300 feet above the ground rather than directly over the void. This gives passengers (or you) a dramatic depth perspective.

Use Shift+Z to toggle the instrument panel overlay for minimal screen clutter. For even more immersion, fly with a virtual co-pilot or use air traffic control voice add-ons.

Using External Camera Angles

To capture the scenery from different perspectives, utilize Prepar3D’s View → New View system. Create a separate camera that looks back at the aircraft from a fixed point on the ground or a chase position. Free camera add-ons allow you to orbit the airplane while in-flight. Some popular tools:

  • ChasePlane – smooth head-shake effects and customizable camera presets.
  • EZDok Camera – advanced pan/tilt/zoom controls.
  • OpusFSI – dynamic cameras linked to aircraft state.

Switch between cockpit view and external views to appreciate both the terrain and your aircraft. Consider flying a formation flight with AI traffic or a second PC to get external shots without leaving the pilot seat.

Recording and Sharing Your Tour

Capture the beauty of your AeroSimulations scenery with these methods:

  • Screenshots: Press Print Screen (or use a dedicated screenshot tool like MSI Afterburner). Use a high-resolution monitor and HDR settings for vivid colors.
  • Video recording: use NVENC or OBS Studio to record at 4K/60fps. Compress with H.265 codec for smaller file sizes. Add music or narration in post-production.
  • Flight tracking: enable Prepar3D’s flight data export to share your route on FlightAware or ForeFlight for real-time tracking (if connected).

After the flight, review your route and note which landmarks were most impressive. You can later edit the flight plan to focus on those areas. Post your videos to YouTube or Vimeo, and share screenshots on forums like AVSIM to inspire other simmers.

Advanced Techniques: Creating a Themed Tour

For a truly immersive experience, design a tour around a theme: “Volcanoes of the Andes,” “Alpine Passes,” or “Lighthouse Coastlines.” Use historical or geographic context to weave a narrative. For example, follow the route of a famous explorer or recreate an aerial survey of a national park. You can even use AeroSimulations’ custom object placement tools to add your own “Easter eggs” like a campfire or a tiny airstrip in a remote valley.

Prepar3D allows you to create mission objectives via the SDK. Set checkpoints over landmarks and prompt the pilot with textual descriptions. This turns a simple flight into an interactive tour with learning opportunities.

Optimizing Performance for Dense Terrain

High-detail AeroSimulations scenery can stress even powerful systems. To maintain smooth frame rates:

  • Reduce autogen draw distance in scenery settings.
  • Limit LOD radius to 5–7 miles.
  • Disable unnecessary CPU add-ons (e.g., AI traffic) in remote areas.
  • Use Prepar3D’s Frame Rate Limiter (set to 30 or 40 fps) rather than letting it run wild.
  • Defragment your terrain cache periodically: delete files in %PROGRAMDATA%\Lockheed Martin\Prepar3D v5\Terrain\ and let P3D rebuild them.

Test your settings before a long tour. If stuttering occurs, lower mesh resolution one step. The visual difference between 5m and 10m mesh is often minor in general flight but can significantly improve FPS.
