RF range analysis (v0.8 beta)

The RF range analysis tool is currently in an experimental, basic state. Check back soon for improvements.
Flights to be analyzed must have at least a duration of 30 minutes and contact with 5+ other aircraft while flying.
Choose a Flarm IGC File, recorded with firmware version 3.11 (August 2007) or newer to analyze.

Please be patient while file uploads, there is no progress indicator...

Technical information

Flarm stores the relative position of other aircraft, when the first and last contact occurs, within the IGC file. This data is then analyzed to determine the transmission range. As the transmission depends equally on your and the other aircrafts performance, which is unknown, a large number of datapoints must be collected. The inherent limitation of this analysis is that it can only examine and show successful transmissions. Therefore it can indicate areas of confirmed performance, but can only hint at areas with no reception, as there will be little or no data from there!

How can I improve the transmission range?

Check the Installation Manual to see if all rules and recommendations have been followed
Relocate the RF antenna to another position, as far away as possible from any metal / carbon
Try a different type of RF antenna

Should I try to improve the "Maximum distance"?

Distances beyond 12km are normally a sign that the performance is not evenly distributed in all directions. Therefore a big "Maximum distance" could be bad for overall performance.

Sample Analysis

The data below is from a standard Flarm, with orignal antenna, mounted on the instrument panel of the rear seat in a Duo Discus.
The transmission range in flight direction is clearly affected by the attenuation caused by the front seat pilot and fuselage.

Disclaimer

This tool performs a statistical analysis of past data, based on data supplied by the user.
The results of this analysis may differ significantly from actual, individual performance.

Look outside!

Never rely on FLARM. A vigilant effective lookout is required at all times!
