New map feature – everything at a glance

Release 4.0 brings a completely new map feature to Vario One. Topographic maps, real-time wind data, airspaces and thermal hotspots – all combined in a single, clear view.

This update changes the way you plan and execute your flight – from the ground to the air.

1. Topographic and satellite maps

The map offers two display modes:

Topographic map – with contour lines, terrain details and slope gradients. Ideal for flight planning and identifying thermal triggers.
Satellite view – for a realistic look at the terrain. Particularly useful for assessing landing spots, forests and buildings.

Setting a pin

By long-pressing on the map you can set a pin to mark important points:

Planned takeoff site
Destination or waypoint
Alternative landing spot
Meeting point with retrieve driver

2. Integrated instruments on the map

During flight, the most important instruments are displayed directly on the map. You don’t need to switch between screens:

Altitude – your current flight altitude in meters
Speed – your ground speed
Climb/sink rate – current vario value in m/s

Red wind arrow

At the edge of the map, a red wind arrow shows the current wind direction and strength. This gives you all relevant data at a glance – map, instruments and wind in one view.

3. Holfuy wind stations worldwide

Vario One displays Holfuy wind stations directly on the map. Holfuy operates weather stations at flying sites around the world. The data is updated every 10 minutes and shows you:

Current wind speed in km/h
Wind direction as an arrow on the map
Gusts – maximum wind speed in the measurement interval

This is particularly valuable:

Before takeoff – what are the current conditions at the launch site?
In the air – how is the wind developing at other stations?
In unfamiliar areas – what conditions prevail at a flying site you’ve never visited?

4. Airspaces from Open AIP

The airspace display is based on data from Open AIP and is shown directly on the map:

Control zones (CTR) – color-coded and recognizable at a glance
Restricted areas – clearly delineated so you can avoid them
Danger zones – with information on activation times
Other airspaces – TMZ, RMZ and other relevant zones

This allows you to plan your flight route without accidentally entering restricted areas. Airspaces are displayed directly over the topographic map, so you see terrain and airspace boundaries simultaneously.

5. Thermal heatmap (KK7)

The KK7 thermal heatmap shows you areas where pilots have found good thermals in the past:

Based on thousands of flights worldwide
Displayed as a colored overlay on the map
Warm colors (red/orange) = strong thermals
Cooler colors (yellow/green) = weaker updrafts

This is particularly valuable when you:

Are exploring a new flying area
Want to optimize your cross-country flights
Are looking for thermal triggers on unfamiliar slopes

Everything together – the full picture

The combination of all five layers makes Vario One 4.0 a comprehensive planning and flight instrument:

Topographic map for terrain details
Integrated instruments for real-time data in flight
Holfuy wind stations for current wind conditions
Open AIP airspaces for safe route planning
KK7 thermal heatmap for the best thermal areas

Plan your flight on the ground. Execute it in the air with all relevant information.
