ALPA Weather Control is not a weather engine and does not replace Active Sky.
It is the missing control layer that makes Active Sky practical to use during a flight.
ALPA Weather Control is a remote weather control interface for Active Sky, designed for pilots who want immediate, intentional control of weather without opening the Active Sky application, editing METARs, using the MSFS toolbar, or breaking immersion.
Active Sky must already be installed and running. ALPA Weather Control works alongside it and gives you fast, direct control exactly when you need it.
The program runs with Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024 and connects directly to Active Sky FS using the official HTTP API. Weather is controlled from an external tablet, PC, or mobile device over the local network, keeping your focus inside the cockpit.
Why you want this product:
• Change weather instantly during a flight without pausing or interrupting the simulator
• Switch between Live Weather and Custom Weather at any time with a single tap
• Inject realistic training scenarios based on Active Sky logic, including:
– Clear skies with calm or user-defined surface winds
– Overcast and low cloud conditions for IFR training
– Rain and storm conditions with wind and turbulence effects
– CAT I, II, IIIa, IIIb low-visibility ILS conditions for procedural training and approach practice
– Hurricane preset for extreme weather scenarios (110kt winds gusting 140kt, severe turbulence)
• Adjust wind direction, wind speed, and gusts on the fly without touching METAR strings
• Realistic turbulence with five intensity levels (None to Severe) using dual-path injection - combines METAR aloft layers with live in-sim effects (turbulence, windshear, updrafts, downdrafts, thermals) for variety and authenticity
• Apply changes immediately through Active Sky without restarting the simulator or Active Sky
• External control over your local network - designedl for home cockpits and ProSim setups where MSFS 2020/2024 wheather presets are limited and accessing the main PC during flight is inconvenient.
What this product is not:
• It is not a standalone weather engine
• It does not generate weather by itself
• It does not replace Active Sky
ALPA Weather Control is built for serious simmers, home cockpit owners, flight training environments, and fixed-base simulators who need fast, reliable, distraction-free control of weather during flight, not before it.
Great tool! It allows to have full control on the weather (if you use Active Sky) and runs very well. Great the capability to use it on a second device. I had a little issue at the first run and the support was super fast and effective. I see further potential enhancements for the tool (presets saves, more options and wetaher configurations) and I hope that the developer will put those in place.
