## About This Content
Active Sky Next, the most widely used weather engine for PC flight simulation,
provides an entirely new level of realism to your FSX: Steam Edition
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!

With ASN, your skies will be accurate, smooth, visually stunning and
uncompressed. 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 a 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.
