The Next Revolution in Weather Realism

Active Sky Next brings an entirely new level of realism to your simulation experience!  Advanced technologies enable incredible levels of accuracy and smoothness.  Realistic radar simulation, cloud position awareness and synchronized ambient effects, brand new air effects, brand new thunderstorm depictions, microbursts, thick overcast, smooth cloud transitions, variable cloud areas, voice weather briefings and forecast data integration are just some of the features that await you!


Active Sky Next (ASN) is the next weather simulation engine from HiFi Technologies, Inc. In development for 3 years, this new version of Active Sky has a completely new depiction system to enable enhanced visuals, accuracy and smoothness never before possible.

Using new low-level weather control techniques, the new depiction system eliminates many problems faced in the past, including inaccurate cloud locations, inaccurate coverage, thin overcast and excessive coverage gaps, non-smooth cloud transitions, inaccurate winds, and required compromises in depiction settings.

With ASN, your skies will be accurate, smooth, visually stunning and uncompromised. No longer must you configure complicated settings to achieve accuracy in certain areas while compromising others. You can have it all, all the time.

ASN also introduces, for the first time ever in a weather engine: Complete cloud position awareness, synchronized cloud-based ambient weather effects and an integrated accurate radar simulation. Precipitation is accurately depicted in the proper locations within and below appropriate cloud structures. Entering or exiting a cloud brings an appropriate change in precipitation, visibility and turbulence. The exact position of clouds and precipitation cells are always synchronized between the simulator depiction and the radar display.

Thunderstorms have been given great attention, utilizing the new depiction system, ambient effects, radar and cloud position synchronization. Completely new microburst, updraft and downdraft, enhanced turbulence and wind-shear effects combine to make thunderstorms beautiful yet dangerous. Using the new radar system will be key to safe piloting in the vicinity of these storms.

Full International Airmet/Sigmet simulation is now provided in real time weather mode, with airmet/sigmet areas shown visually on the map and/or gauge.  These areas are now also synthesized, influencing weather depiction appropriately.  If a Sigmet warns against severe turbulence, convective activity, or icing, you can expect to encounter this appropriately during your flight.

New voice weather briefings, a new intuitive user interface with resizable/undockable and multi-window support, redesigned high-resolution wake turbulence simulation and enhanced air effects are just a few of the other new features in ASN.

    This is an excellent weather program. Weather is projected highly realistic than any other weather program for Flight Simulator..No sudden weather changes like with other weather engines. Also improved fog, haze, turbulence and wake turbulence. The interface is easier and simpler to use as well.

    Forget the 5 star rating this deserves 10 Stars! I did NOT purchase ASN from SimMarket, I did however purchase it from another vendor and it is easily THE SINGLE BEST WX ENGINE EVER. Still not convinced from other reviews and ratings, just go to HiFi' website and download the FREE FULL TRIAL version to try for 7 days with NOTHING locked out or non-functional. That's right a full version trial for 7 days that is 100% functional as if you purchased it, and you don't even need a credit/debit card to try it, just an e-mail and your IP address, and that's it. Click on the YouTube video above for my full review of ASN, I promise you will not regret trying/purchasing this WX Engine!
*Note: I also strongly recommend purchasing REX 4 Texture Direct to use in conjunction with ASN, they both work seamlessly together and in fact compliment each other to the fullest extent!

    I'm OpusFSX and FSGRW owner, but watching screenshots and video around the web, I was really impressed and I decided to buy it....It's the best weather engine ever! NO WAY!

    TL/DR version: Great fun. Trials are rare in Flight Simming, use it!
January 6, 2014 around 23:00 UTC. Approach to EDDL from EDDH. The 737-800 Reg. D-ABKG is shaking violently,
FSPassenger are screaming and would be starting to fly around with recorded accelerations of 0 to 2 G
but the Autopilot is doing a good job.
The slow 2.2 Ghz dual core CPU is not complaining, and the dark cloudy sky looks nice at lowest settings.
Final approach, ATC is getting nervous.
"BER1, go around!"
Huh? Traffic on the runway?
A mistake by them, as the gear was down unlike the controller said in that typical over-emotional way again.
Well, more fun for the passengers...
Attempt number two, let's see what autoland does...
Not a good idea. This weather requires a real pilot, and the plane hits the ground a bit hard
with the left gear and close to the edge of the Runway.
No way to talk about survivability here without a proper crash detection system.
Maintenance will certainly find some kind of deformations.
