It may just be worth reminding ourselves that this stuff (whether it be Flarm, PAW or SE2) does work. With my insurance renewal the insurer sent me a copy of the 2019 BGA Accident summary (maybe they were trying to tell me something
) It had an interesting chart on MAC, looking Glider:Glider and Glider:Other over the last 45 years. You can see a distinct reduction in Glider;Glider since Flarm started to be introduced around 2005 after 15 years upward trend.
Hopefully adoption of more EC and better interoperability will start to reduce the "Blue" bars. I know the numbers may be relatively low, but the survival rate is probably <50% - we may even be starting see the glider:other numbers declining in 2014-2019, bit early to say just yet......
So I know it's tempting to say "I've spent money on this but what does it do"...... but there is a long term benefit. I have 2 good friends who might be alive today if Flarm had been available in the 1980's. Of course MAC is not the only (or even the top) cause of GA fatalities, but it is one that technology can help with......
PS: I believe that in all of these statistics there is only one collision between 2 gliders that were both Flarm equipped.
