YOUR FLIGHT. YOUR ATMOSPHERE.What makes it Aloft
THE WORLD BEHIND YOUR WEATHER

One planet.
Layers of possibility.

Look inside the atmosphere Aloft draws from. Explore current weather sources around the world, from airport reports to winds high above the clouds.

HOW ALOFT USES IT

Aloft reads wind speed and direction through 12 model pressure levels, blends nearby reports at the surface, and builds the simulator’s wind layers.

Global sources. Weather built around your aircraft. This is a coarse view of Aloft’s source data. The desktop engine combines nearby reports and a detailed vertical profile into one evolving simulator weather state.

THE TRANSITION ENGINE

A new report.
A continuous sky.

A new weather report shouldn’t feel like a new world. AloftWX approaches each new condition gradually, keeping the weather moving between updates.

A Windows desktop app handles the weather. A small in-sim package brings it into Microsoft Flight Simulator 2024.

New weather targetWith AloftWX

When a new report changes the wind, AloftWX moves toward it gradually. The destination changes; the transition stays continuous.

LIVE

Fly the weather outside.

Nearby weather reports meet the atmosphere above them. Surface observations and model data work together, from the runway to cruising altitude.

Surface observations + atmospheric model

REPLAY

Pick a moment. Fly it again.

Explore historical conditions through the same weather engine. Choose a time and take a different day into the simulator.

Historical coverage varies by date

CUSTOM

Make the approach your own.

Set your own conditions for the flight you have in mind. Build a low ceiling, set the wind, and practice with purpose.

Your conditions. The same transition engine.

Built for MSFS 2024 on Windows. Weather is applied globally around your aircraft; AloftWX does not create independent weather cells across the map.

Before your flight

Which simulators are supported?

AloftWX is built for Microsoft Flight Simulator 2024 on Windows x64. It does not support MSFS 2020, X-Plane, macOS, or Linux.

Can I try AloftWX yet?

AloftWX is in development. The closed beta will be free and by invitation, with invitations shared in Discord. There is no announced release date.

Does it change weather across the whole map?

The simulator applies one global weather state. AloftWX updates that state around your aircraft as you fly; it does not place separate weather systems at different locations.

Where can I ask questions or share feedback?
