We are an independent studio building high-fidelity tools for desktop flight simulators: real data, real meteorology, and interfaces that feel like the flight deck. We started with the weather.
One studio, a growing shelf of tools for the desktop cockpit. Each one stands on its own, built to the same standard.
Real-world live weather for Microsoft Flight Simulator 2024.
A living, three-dimensional atmosphere injected into MSFS 2024 in real time: winds aloft, layered clouds, pressure, precipitation and turbulence, evolving as you fly. Live, historical and sandbox modes, in a glass-cockpit interface.
One hub to install, update and manage every StrataSim product.
A single desktop app that installs our products, keeps them current and handles your licenses, so the whole shelf stays one click away. Free, and the easiest way to get set up.
New tools for the flight deck are in the hangar.
We build the tools we wish existed. There is more in the pipeline beyond weather. Want to know first? Say hello.
StrataSim Designs is a small, independent flight-simulation studio. We care about fidelity over flash: software grounded in real data and real meteorology, that does what it claims and stays out of your way. We sell it honestly, support it properly, and keep improving it.
We have been flying these sims since the FS98 days, back when clouds were sprites and the weather was a slider. The better part of three decades of patch notes, payware, hard landings and 2 a.m. tweaking later, we know exactly what separates a tool that gets uninstalled in a week from one that lives in your startup folder for years.
That pedigree is in everything we ship. We do not chase trends or pad a feature list: we build a small number of things, build them to a professional standard, and stand behind them. If it carries the StrataSim name, it earned it.

hello@stratasimdesigns.comPress Release
An aircraft-following, multi-model weather engine for MSFS 2024 and 2020 that resolves the real atmosphere at your exact position, every moment of the flight.
StrataSim Designs today announced the general availability of StrataWx, a premium live-weather engine for Microsoft Flight Simulator 2024, with full support for MSFS 2020. StrataWx reads your aircraft's position continuously and injects real-world weather resolved for that exact point in space and time, so the sky you fly through reflects the atmosphere that is actually out there, not a coarse approximation of it.
Where most weather solutions hand the simulator a broad regional snapshot, StrataWx behaves like a dedicated meteorological co-pilot. It follows the airplane, looks ahead along the route, blends real station observations with a fusion of global forecast models, and renders a coherent, evolving atmosphere from the surface to the flight levels.
StrataSim Designs is an independent flight simulation studio focused on one thing: making the simulated atmosphere feel real. StrataWx is the studio's flagship product, built for the way real flights actually encounter weather. The team builds in the open, ships frequently through an automatic update channel, and treats pilot reports from the field as the most important signal in the development loop.
StrataWx is a signed Windows desktop application paired with a lightweight in-simulator panel. Together they form a real-time weather pipeline:
StrataWx is not limited to right now. Historical mode replays a past date from reanalysis data. Sandbox mode lets you author conditions by hand. Hybrid mode layers an authored sky over the live picture. Every mode runs through the same smoothing pipeline.
For virtual airlines and serious general aviation flyers, StrataWx folds weather into the dispatch workflow: a Flight Plan view with dispatch tabs and a route weather ribbon, optional route-aware weather preload, SimBrief route briefing, a generated ATIS, winds-aloft export, route file import, and historic winds export.
The simulator's native Live Weather is a solid baseline, and StrataWx respects it: when a user wants the sim to own the sky, StrataWx steps aside cleanly. But the built-in system is broad and coarse. It does not resolve the atmosphere for your precise position, it has no historical replay, no manual authoring, no hazard or turbulence modeling, no ATIS or dispatch integration, and no continuous, observation-anchored blending between stations.
For years, serious weather in the simulator meant one established add-on. We respect the road it paved. StrataWx is our answer for the current generation of the simulator: a native, modern engine that fuses multiple global models rather than relying on one, anchors temperature and pressure to the aircraft and the station the way a briefing actually works, and threads weather into flight planning. We are also honest about the platform's hard limits. No external engine, including our leading competitor, can paint discrete convective cells onto the simulator's onboard weather radar, because the simulator exposes a single global weather state to inject into. We tell you what works and what does not, and we keep pushing on everything that can be improved.
"The atmosphere is the most important character in a flight, and for too long it has been the least convincing one. StrataWx exists to fix that. We resolve the real sky for the airplane, follow it through the whole flight, and smooth every transition, so the weather stops being scenery and starts being something you fly." The StrataSim Designs team
StrataWx is available now for Microsoft Flight Simulator 2024 and Microsoft Flight Simulator 2020. The application is code-signed for safe installation on Windows and keeps itself current through an automatic update channel, with both stable and beta tracks.
