Using Radair4D

Radair4D, shows pilots relevant weather data.

Before flight, a flight plan can be registered in our app and the necessary weather information downloaded.

By pushing the flight button, just before take-off, our weather information, travels along with pilots!

Updates of the latest weather, can be downloaded during flight.

An unique feature in our flight app!

Active thunderstorms can be detected with an estimation of their top altitude, intensity, maturity stage and near future movements.

Advance awareness before the arrival of a Storm can add to safety, especially in Aviation!

Being the only one in the world with a feature like this, our team is very proud to have developed this.



Our rain layers offer pilots the option to analyse rain probability.

The three rain layers on Radair4D are:

Convective Rain: In bright colours showing the status of rain convection

Rain Probability: In different tones of blue showing the rain probability

Rain Composite: An overview of both at one glance



Flying IFR or VFR, clouds are relevant for all pilots.

Cloud thickness, as well as cloud tops and bases are shown on Radair4D.

During flight, a vertical graph will appear on the app, indicating the clouds expected en route.

By selecting the desired flight level to monitor, Radair4D shows a 5 hours future look of the movement of cloud layers.
