Introducing HiFi’s first weather engine for the X-Plane platform……
Active Sky XP (ASXP) brings the popular award-winning Active Sky weather engine to the X-Plane platform for the first time. Using a hybrid weather depiction interface through X-Plane 11’s weather API, a realistic, high-performance and high-fidelity weather experience is realized.
- Active Air Effects
Replaces internal X-Plane turbulence and air effects, providing enhanced turbulence, drafts, thermals, terrain-based wind effects, surface friction, gusts, variability, wake turbulence, microbursts and more
- High-Performance Weather Depiction
Uses internal X-Plane 11.2x/11.3x cloud depiction for maximum performance and smoothness, with multiple weather depiction modes including theme cell “real weather” mode and global static mode – VR compatible and optimized!
- Active Sky Weather Engine
An evolved version of the Active Sky platform brings the core features that made Active Sky the leading weather engine for other platforms: Advanced weather synthesis and interpolation, high-resolution global winds aloft, realistic air and atmosphere effects, a comprehensive weather data network, integrated visual mapping and planning, and much, much more
- Voice Weather Delivery
Active Sky ATIS and Flightwatch are available at any time by listening on 122.00, 122.02 or 122.03 for closest station, actual/current interpolated conditions and destination weather reports, respectively
- Surface Crosswind Attenuation
Optional, for better ground handling in crosswind conditions while preserving headwind/tailwind component for performance accuracy
- Mobile Companion App
Use any device/browser to connect with Active Sky over your network and view and control the weather
Features, specifications, requirements and pricing subject to change
Not a complete visual cloud rendering replacement
- We have put our previous X-Plane visual cloud rendering replacement efforts on hold (until next year) due to performance considerations and changing API environment/tools that are not yet finalized
- We expect our visual cloud rendering replacement technology to debut in Q4 2019, subject to change based on many factors
- ASXP features high-performance cloud depiction with a focus on conditions accuracy, utilizing the X-Plane internal cloud rendering via a hybrid API approach, with two different modes available
- ASXP also features an optional high-performance photo-realistic cloud texture replacement with a simple texture installation wizard
Windows 64-Bit (v7 or later) Only

Frequently Asked Questions
Q: Are cloud texture replacements included?
A: Yes, an optional cloud texture replacement, evolved from the newest ASCA content and designed specifically for X-Plane 11.26/11.30+ is included. Two different variants are available, high performance, which is softer and lower resolution, and high detail, which is higher resolution, with harder edges. ASXP also works great with any other textures and other visual enhancements.
Q: Is a complete cloud visuals depiction replacement included?
A: No, not at this time. HiFi is working on such technology and hopes it will be ready to debut sometime in late 2019.
Q: Are smooth cloud transitions provided?
A: When moving over the ground, clouds transition naturally using the default theme depiction mode, since variable weather is shown on screen, i.e. clear wx ahead, cloudy conditions below. You will see the cloudy area transition properly to clear, both areas properly depicted at the same time. In this case, geographic transitions are intrinsic without any redraw. When using Global Static depiction mode, the same conditions are represented across the sky, so when moving from cloudy to clear, the clouds will redraw. In either mode, the clouds will redraw when the weather is updated. Redraws can be minimized by using default theme mode, setting a standard download update interval (i.e. 30 minutes), and using the “Prevent downloads on approach” option, if desired. Completely smooth transitions as per our P3D and FSX products “Smooth Theme Reload” feature is not provided. We will be providing our own new smooth transition technology, tightly coupled to our cloud dynamics technology, when we replace the cloud visuals depiction.
Q: Will the future cloud visuals depiction replacement be provided as a free update?
A: No, future cloud visuals depiction technology specifications and how it will be packaged are yet to be determined, based on many unknown factors. We will provide more information and development news on this as progress continues. ASXP v1.0 focuses on the core weather environment as a high-fidelity weather engine, currently utilizing a hybrid approach to X-Plane’s weather depiction and APIs for the best possible realism, accuracy and visual quality possible.
Q: Will any future updates be provided free of charge?
A: As always, we constantly work to maintain and enhance our products, with several free updates planned. The details of what would be included in such updates are yet to be determined.
Q: Will future major upgrades (i.e. 1.0 to 2.0) of ASXP be provided for free?
A: No. Our future development capability and expansion in such major areas is subject to significant additional cost and as such would planned to be offered as separate products or major new versions of existing products. We always strive to provide a great value, and typically always offer discount pricing for upgrade versions for previous product generation users.
Q: Will support for any new simulator versions (i.e. XP12, XP13) be provided for free?
A: Not likely. If little change/update is required to support the simulator, then we could easily provide a free update. However, any significant re-design would most likely be provided within a new major ASXP product version. We typically offer generous discounts for upgrading previous-generation products.
Q: Will a discount be offered to HiFi customers of other products/platforms?
A: We have planned a reduced promotional launch price, estimated at $39.99 USD, in appreciation of our customers who have enabled us to create ASXP. We expect to increase pricing some time after launch, with specific dates yet to be determined. Pricing is subject to change.
Q: How does ASXP match up to competitive products?
A: At HiFi, we take pride in our unique approach to product design and development, with a specific focus on function, accuracy and high-fidelity features. It’s proven to be a successful approach that has enabled continued development for 20 years now, and we don’t plan on messing with that formula. Other developers have created amazing and great products and have given a lot to the community, with each product line having its own unique features, along with specific pros and cons. All products and their developers have enabled continued innovation, as we are all striving for a better experience. We always recommend supporting all developers and products, and use whatever you like best for your needs. Your support is instrumental in enabling amazing new things, from us, our competition, all developers and the entire community.
Q: How evolved is ASXP compared to ASP4 or AS16?
A: ASXP has been in development for 3 years. ASP4/AS16 on the P3D platform for about 8 years, and AS16/ASN/ASE/AS Legacy products on the FS platform for about 20 years. X-Plane is an entirely new platform for us, and we are just getting started. With that said, we like to think we have a lot of experience in this realm and have made some incredible accomplishments in the 3 short years we’ve been working on it. While it certainly isn’t as evolved as our previous platform products, yet, we’re very happy with the results and excited about releasing our first wx engine for the X-Plane platform.
Q: Is there an SDK/API for other add-ons to interface with ASXP
A: Yes. Most previous-platform API functions are available. Exceptions include radar comms and other in-process API functions. The http-based universal API method, as well as the exported weather data files are fully enabled.
Q: Is radar included?
A: X-Plane 11 has internal precipitation dynamics and radar functionality, that certain default aircraft and other 3rd party-aircraft are currently using to provide radar precipitation display. ASXP works with this completely as it uses X-Plane’s internal cloud/wx depiction system at this time. We plan to offer our own radar/precipitation technology later, along with our planned visual depiction system replacement.
