AIR Glide – Sensor Unit

Our AIR Glide sensor unit is a sophisticated sensor platform, that integrates 14 different sensors and a fully IGC certified flight recorder in a compact device. With a combination of 14 sensors, the relative air-mass movement and wind arround the aircraft is measured in real time. Independent of his flight direction the pilot sees real time air-mass and wind data updated repeatedly every second.

The sensor unit contains 3D accelerometers, 3D rate gyros, 3D compass sensors, and a highly accurate GPS receiver. This makes the Sensor Unit a full-scale inertial measurement unit. These sensors, combined with 4 pressure sensors for cabin-, TE-, static-, and dynamic pressure, generate a vast amount of data that is processed in advanced sensor fusion algorithms to compute the aircrafts current attitude, speed, position, and to determine current wind and vertical airmass movement.

Small and versatile

Even though its packed with technology, the sensor unit is very small. This makes installation within its requirements (straight, level and without too much magnetic interference) easier to accomplish. The data interface and power supply works with a single cable with robust industrial technology cables and connectors. Cable lengths of over 10m are possible. Flights from the integrated IGC Logger (triadis RU3) can be downloaded from any connected display unit.

AIR Glide Sensor unit and conventional variometer in comparison

Average Variometer

  • changes in pressure between static pressure, asbolute pressure and TE-pressure.
  • sometimes acceleration is also used

Butterfly Vario

  • changes in pressure between static pressure, asbolute pressure and TE-pressure
  • Inertial measurement unit computes 3D-position in realtime comparing 14 different sensors
  • Sophisticated data integrity sensing.

Live Wind – a new dimension in wind calculation

The permanent computation of wind direction and strength (we call this “live wind”) helps pilots interpret their surroundings in a new way. You can see how wind becomes weaker or still in the center of lift and how air flows into and out of a thermal. Local wind systems in mountainous regions can be easily discovered.

The vertical airmass information (VAM) offers a gust independent view on the current vertical airflow, easier to interpret and less prone to wrong indications than average netto variometer signals.


The Vario helped very much and not only in wave. The (wind) indication changed very quickly and you could get extra information about convergences and wave spots in a way that was not possible before.
