ASFS Weather and Cloud Depiction Specifications
ASFS Preset Weather Depiction Mode
ASFS Preset weather depiction mode features advanced weather preset conditions control for the best accuracy within the preset depiction capabilities, and full use of the Active Sky weather data and synthesis system including historical and custom weather options. This is recommend for those desiring the highest levels of conditions realism and challenge, especially for IFR ceilings and visibility, as well as long distance route planning, wind and fuel calculations:
- Available with LIVE weather, HISTORICAL weather, and custom weather
- Wind, gusts and variability control (surface and aloft, up to 60,000ft)
- Cloud layer control
- Precipitation control
- Ground snow cover control
- Temperature and humidity control
- Barometric pressure control with advanced temperature-adjusted pressure effects (appropriate corrections required for safe and/or expected IFR terminal procedures in colder or hotter temperatures)
- Visibility simulation through advanced humidity control, fog layer generation and intelligent visibility graduation and smoothing
- Smooth cloud and conditions transitions with configurable smoothing rate
- Cloud scene scattering and variation control for variety within the preset depiction area
- Sky conditions control for multiple cloud type variations
- Thunderstorm scene handling for improved visual height and realism
- Weather-cell-based presentation with surface data prioritization based on flight plan
- Transitions handling (updates conditions smartly depending on flight plan and flight stage)
Passive Depiction Mode
Passive mode is used with live weather and allows MSFS’s internal live weather depiction to take full control of weather depiction in the simulator, while Active Sky FS provides Active Air Effects and all other non-depiction features (mapping, planning, voice features, conditions report, web companion app, etc.) This can provide better regional variation and cloud variations outside of Preset control, recommended for LIVE WEATHER VFR and casual flights where visuals and effects are more important than weather conditions accuracy.
Active Air Effects
Provided in either depiction mode, Active Air Effects enhance your flight with turbulence, drafts and more:
- Clear air turbulence
- Internal MSFS turbulence compatibility (for combined ASFS-applied and internal MSFS-applied turbulence effects)
- Updrafts
- Downdrafts
- Microbursts
- Thunderstorm vicinity turbulence and draft effects
- Gusts, wind variation and gust-related turbulence
