FAQ about Thermocompass


Is it possible to test this Instrument? A: Yes, of course. You will have to buy at least a HOLUX FunTrek130. Software you can download here. Install and run,  Maps of the desired area can be found in paraglidingearth.com, or Order here.

Buy the device can be on the Internet. FunTrek130 I do not sell. Other models of devices are not suitable.


 Is there some new video with english explanations of how it works? A: Video


This is regarding your post in Indian paragliding face book page, " Test pilots are required to test the new device. " Can I will like to be the test pilot? A: Testing period is over. You can just use this device.


Why HOLUX FunTrek 130? A: This device works for a long time, well readable in the sun and in contrast to the analogues have additional sensors on board: the magnetic compass, accelerometer, Barometric sensor. The system win CE 5.0 is weakly closed and allows modification of the device without loss of efficiency.

Why do you need thermal maps?
- At low altitudes to detect triggers on duty.
- At high altitudes - to select the most thermals direction. Unfortunately, not all trigger's easily seen from a sharp angle, especially the small hills and ravines.

Can we trust the data of thermal compass?
- You can trust completely, especially if from time to time to carry out wide flat spiral.
- For the accordion too much work. You could throw a couple of photos.

What determines the detection range of thermals? 
- The first of the tandem-wing suspension. How Sensitive system to turbulence - the further away you can find a stream.
- Fly is not a straight line (the snake)

If I randomly pull brakes and suspension juzat in how this will affect the unit?

- Virtually no effect because the oscillation frequency of the wing from the brakes are very different from the frequency we need.

Why is the map screen does not show the core thermals and track?

 During the development of software for thermal compass were analyzed approximately 1600 flight tracks of Leonardo. Most thermals as sharply ends and attempts to return to the stream failed. The analysis showed that it is often associated with an almost horizontal overflow of the weaker thermals in the nearby stronger curvature of the trajectory or the thermals from the cloud. In this case, the device would continue to properly extrapolate the trajectory of thermals in the place where it no longer exists. Compass also selects the most powerful epicenter of the disturbance. In other words, even in a weak stream, he will point to a more powerful stream nearby.

Affect whether or not the instrument of discharge and how?

  - Virtually no because the nature and frequency of disturbances from downstream differ from thermal and mathematical filter cut off the program.

I found that the maps are not alligned ! I guess the center of the map should be my position, right?

so there are not aligned with the igc lon/lat pos. A: Maybe you accidentally clicked on the bottom left of the screen - this is the place predicted thermal. And your real location - click on the screen at the bottom right.
What is the meaning of the blue line sometimes all changes to green map screen? A: Maps can be different - light and dark. To better see the pointer - automatically switches to color.
On map screen you have normally a long blue line with an arrow and a some red dots. the arrow changes sometimes to green and the line to a kind of light blue not green? A: a long blue line - AVERAGE wind direction. Triangle - the wind is "now", a some red dots - thermocompass pointer (arrow) - direction to fly. Color varies from color maps.

So what would be the best screen for flying ? map or compass?

To find thermal zones - maps screen. Near a thermals - compass. 

You should somehow integrate more the compass for thermal direction. It is jumping around too much...

 I expect that you will not pay any attention to the numbers under the white arrow. When values greater than 0.5 (there is a sound variometer) - then you need to follow the compass. The rest - just noise.
