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!

Higher Performance
New cloud depiction techniques, new storm depiction variations, and improved smooth theme reloading brings new levels of performance with reduced cloud-drawing overhead

Increase Data Resolution and Coverage
Enhanced global gridded weather data synthesis provides new kinds of data and over 10 times the previous resolution, offering much improved realism and coverage for all kinds of conditions in all areas, regardless of availability of METAR reports

Improved Oceanic and Sparse-Coverage Weather Accuracy and Variation
Utilizing the new data resolution and coverage, oceanic and sparse-coverage flights now include realistic weather conditions and cloud coverage that does not rely solely on interpolation

New Overcast Pattern Fix
Overcast stratus cloud layers in FSX are no longer subject to ugly and obvious rectangular patterns during dawn and dusk lighting scenarios when using the new Overcast Pattern Fix, part of the new Visual Fix options

Improved cloud-based effects
A new local cloud detection process greatly improves the synchronization of cloud-based effects including visibility reduction and turbulence

New in-sim Weather Request Menu
Receive weather updates for local area, flight-plan stations, and winds aloft via an integrated SimConnect text menu that can be used directly within the simulator

New Prepar3D-based Enhancements
ASN for P3D is now compatible with P3D v2.5 and includes additional performance tuning specific to P3D (ASN SP2 IS NOT COMPATIBLE WITH P3D 2.4 or earlier)

New Dynamic Positional Variation for Sigmets and Airmets
Airmets and Sigmets are now fully dynamic and provide variable conditions simulation for turbulence and icing in addition to convective activity

Improved Stability
New installation and configuration routines provide a smoother user experience

Dozens of additional features, enhancements and fixes that are too numerous to list here!

  • Active Sky Next (ASN) is the next weather simulation engine from HiFi Technologies, Inc. In development for over 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.
  • ASN is now officially available for both FSX (boxed and Steam Editions) and P3Dv2.5. An ASN license entitles users to use both FSX and/or P3Dv2 versions, as long as they are used on the same computer.
