Active Sky for P3Dv4 (ASP4) UPGRADE

Now For The Prepar3D v4 Simulator Platform!

–This Is The UPGRADE ONLY – Updated November 18th, 2017–

PREVIOUS ELIGIBLE PRODUCT LICENSE IS REQUIRED for this UPGRADE VERSION! You must have a valid license key for ASE, AS2012, ASN or AS2016 for FSX Full/Upgrade version (Steam DLC does NOT qualify). When you run this software, after entering your new ASP4 Upgrade Key, the software will ask for your eligible Product Key, which must be entered. If you do not have that key handy, you can also leave the previous product installed and the software will automatically find it. If you’ve already uninstalled the previous product, and do not have your key available, please contact your previous product reseller (or view your order history) to obtain this information.

Be sure you have the correct item in your cart before completing your purchase! If you do not have a previous version of Active Sky that qualifies for this upgrade, Get The Full Version Here!

Active Sky for Prepar3D v4 (ASP4) represents 17 years of weather simulation engine development! Building on the Active Sky weather engine experience, ASP4 brings a new 64-bit ASConnect simulator interface, 64-bit XGauge, new Air Effect enhancements, new Visibility Depiction enhancements and more, all specifically designed for Prepar3D v4!

In-Cloud Motion Effects, Weather Scenarios System, Airborne Weather Radar, P3D Visibility Smoothing and Volumetric Fog Integration, Navigraph Data Integration, Map-based Custom Weather Editing System, Universal Web Companion App, Mapping System and a High-Latitude Cloud Squeeze Fix are just a few of the advanced features included in the core Active Sky platform.

ASP4 also incorporates full integration with Active Sky Cloud Art (ASCA), our graphics add-on for both FSX and P3D. ASCA includes cloud textures, sky textures, and 3D cloud models to transform your skies, while also incorporated Real-Time Dynamic Cloud and Sky Textures! This enables realistic weather-influenced texture variation that reloads throughout your flight without needing to shut down and restart your simulator. You can use any graphics add-on(s) with ASP45, but dynamic texture reloads require the ASP4+ASCA combination.

ASP4 is available in full or upgrade versions. Eligible upgrade products are Active Sky Evolution (ASE), Active Sky 2012 (AS2012), Active Sky Next (ASN), and AS16 for FSX (Cross Platform Upgrade). If you have purchased a license for any of the eligible products, you qualify to purchase the upgrade version at a discount.

Feature Highlights

New ASP4 Features

  • Redesigned 64-bit ASConnect simulator interface with tight P3Dv4 integration
  • Updated XGauge radar and weather display gauge, now in 64-bit
  • New Air Effect Enhancements including Low-Interval Smoothing for a more organic and realistic feel to updrafts, downdrafts, thermals, gusts, sheer, turbulence and microbursts
  • New Visibility Depiction Enhancements including new low and high altitude visibility horizon distance adjustment options
  • New Active Runway Data, showing the active runway in use based on current wind conditions via Map pop-ups, Conditions Screen METAR text and Briefing text
  • General improvements in performance and stability throughout

Incorporates all of Active Sky weather engine previous product technologies including highly-realistic global weather data integration, advanced radar and precipitation simulation, cloud position awareness and synchronized cloud-based effects, advanced air effects, microburst simulation, wake turbulence simulation, and much, much more

Core Features introduced in AS16

  • In-Cloud Motion Effects – Feel the speed of motion while flying through clouds
  • XGauge WX + Radar – Enhanced weather gauge with included realistic airborne radar mode
  • Weather Scenarios System – Challenge yourself with several scenarios including a Microburst Encounter, Gusting Winds, Wake Turbulence, and more
  • High-Latitude Cloud Squeeze Fix – Fly high-latitude areas without stretched clouds
  • Map-Based Custom Weather Editing System – We’ve re-designed custom weather editing and provided a new easy map-based custom weather area manager and weather setting wizard
  • ASCA Integration for Real-Time Texture Dynamics – ASP4 works with any texture/graphics add-ons (including default graphics), but when combined with ASCA, real-time texture dynamics and automatic wx-influenced selections are enabled
  • Web Companion App – Remotely view and control weather using any device on your local network with new webserver/browser technology
  • Map System – Vector Background Options and Background Overlays
  • NAVIGRAPH Data Integration – Airports, Navaids and Fixes now provided by Navigraph! A complimentary expired database is included with ASP4, and regular AIRAC cycle updates are available with a Navigraph subscription



Additional Features

  • Award-Winning Active Sky Weather Simulation Engine – Enhanced Further! – We’ve been enhancing and growing Active Sky since 2000, and this new version expands our weather engine even further than ever before
  • Enhanced Thunderstorm Effects – Thunderstorms are now very dangerous, as they are in the real world, and require avoidance, in most cases, to ensure safe and successful completion of your flights – Flying into heavy cells can result in loss of aircraft control and even airframe stress overload
  • Performance-Focused Design – We’ve taken the previous codebase for Active Sky and re-factored it, tuned it, and re-designed many core areas for increased performance and usability
  • User Interface Improvements – We’ve incorporated user feedback and made dozens and dozens of improvements throughout the entire UI
  • Hybrid Weather Depiction Technology – AS16 uses multiple integration and depiction methods to provide realistic, smooth and correct weather and ambient conditions at all times, while also providing full cloud position awareness to enable advanced cloud-synchronized radar, precipitation and air effects
  • High-Fidelity Data Resolution and Coverage – Active Sky 16 includes enhanced global gridded weather data, global sigmets and airmets, global surface data and global aloft data for much improved realism and coverage for all kinds of conditions in all areas without relying strictly on METAR reports
  • High-Fidelity Air Effects – Wake Turbulence, Microbursts, Downdrafts, Updrafts, Terrain-influenced Drafts, Thermals and more!
  • Smooth Transitions
    Cloud formations, wind, temperature, visibility and every other aspect of your weather is smoothed, transitioned and interpolated for the ultimate in realism
  • Private Server Network – AS16 utilizes the high-performance and high-availability HiFi DataNet weather network with multiple servers in multiple regions around the world, providing high-resolution weather data and historical data archives for the past 2 years
  • Online Historical Data with Playback – Fly in weather at any date/time up to 2 years in the past and have weather update realistically throughout your flight according to hourly-archived conditions
  • Active Sky API – AS16 utilizes an extended version of the Active Sky API, allowing 3rd party developers to integrate and take advantage of advanced radar, icing, wind shear, weather data and weather controlling extensibility
