ASN SP1B released
Posted by Damian Clark on 27 October 2014 07:05 PM

Active Sky Next SP1B has just be posted, for both FSX and P3D versions.  This update provides some fixes pertaining to potential improper airspeeds/pressures/temperatures, and is recommended for all ASN users.

Service Pack 1B:

- Adjustments to initialization process to prevent potential weather depiction conflicts when using certain other add-ons.
- Made hurricane weather respect the "High detail thunderstorms" option.
- Adjusted dynamic CDD adjustment with respected to hurricanes for better performance/CDD calculations.
- Fixed issue where use other other weather add-ons (even when weather option was disabled) could cause ASN depiction issues especially in regards to temperature and pressure (and realized airspeed/TAS performance).
- Added new tool menu action "Disable ASN Weather" which will temporarily disable ASN weather components to prevent potential conflicts when using other weather add-ons even when ASN client is not loaded. ASN weather components will automatically re-enable on next ASN load.

Active Sky Next SP1 for FSX and P3D

Active Sky Next has just been upgraded officially to SP1 and brings dozens of new features, improvements and adjustments to raise the bar even further in high fidelity weather simulation for both Flight Simulator X and Prepar3D v2.4:

  •          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 v2.4 and includes additional performance tuning specific to P3D

  •          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 is a full-featured weather simulation engine from HiFi Technologies that incorporates unique high-fidelity features including realistic radar, smooth weather changes, cloud-synchronized ambient effects, microbursts, wind shear, wake turbulence, vertical air simulation, terrain-based draft effects, third-party integration, high-resolution weather data, historical data access and much, much more.

Active Sky Next for FSX is Released!
Posted by Damian Clark on 09 December 2013 09:29 AM

HiFi’s new weather simulation engine for FSX has just released, and is now available for purchase.  A free 7-day trial is also available!

ASN is being called “the next revolution in weather realism” and brings enhanced realism features made possible by a new hybrid depiction system and ASConnect interface for accurate and dense cloud/weather depiction with fully smooth changes at all times.  360-degree variable cloudscapes, accurate radar simulation, cloud position awareness, cloud-synchronized ambient effects, international SIGMET/AIRMET synthesis, forecast data integration, new mapping overlays, new air effects, enhanced turbulence, microburst simulation, variable in-cloud visibility reduction, advanced wake turbulence, high-resolution terrain-influenced updrafts and downdrafts, ridge lift and thermals are some of the highlights, but many more new features exist.

ASN launches for FSX, and a Prepar3D v2 version is coming soon as well.  A single ASN license works for both versions.

For more information about Active Sky Next, and to try it free for 7 days, visit the ASN website at
