Real world pilots keep moving weather simulation forward

We make everything simple. Interface, logic, design, everything.
Start the application one time and you may never touch it again.
You may start and exit flight simulation many times and xEnviro will handle everything in the background for you.


We love numbers. We work with numbers. We live with numbers.
Number twenty means a lot to all of us both personally and in flight simulation.


Exclusive. Premium. Top.
Oh yes we are.

DarkSpace and Threshold are proud to present the most accurate weather engine for Microsoft Flight simulator 2020. With over ten years of experience with reproducing real weather on X-Plane with realistic training in mind, we have ported the core of xEnviro over to Microsoft Flight Simulator to get the most precise weather in the most popular simulator.


Real-time meteorological data with a refresh interval from 5 up to 60 minutes.
Historical weather data is available at 30 minutes intervals.
Atmosphere condition based on dynamic air parcel prediction model used for real aviation research and training.
Advanced atmosphere topology methods provide accurate cloud thickness and density prediction.
Atmosphere quality includes humidity, pollution and fine particle amount.
Actual wind direction and speed for all levels as well as for the temperature, turbulence and wind shear.
Simulation of in-cloud turbulence.
Surface crosswind components can be reduced during ground roll for users with no rudder pedals.
Seasonal data processed by our servers all year round provides real-time snow coverage.
All the weather and atmosphere-heavy calculations are executed on our servers. Therefore, expect no performance impact on your hardware.
