We could try and work together as a group on this non functioning Flarm problem.
If your Flarm or a friends doesn't work as it should , which is Really well, get some help or give some help to fix it until it does. This mid air is exactly what Flarm was designed to prevent!
But it takes two to Tango. I understand that in Carbon Fuselage ships the install is very important, but obviously that has been worked out a long time ago.
FWIW in my fiberglass LS3a my Flarm has worked well from day 1. It is very easy to update it, and as Ramy stated even if you don't know how to use it, turn it on. The "Lady " will tell you where the traffic is if you have it connected to a talking display. This accident was exactly what Flarm was and could have been for. Its too bad Flarm WAS installed in both ships, but one owner didn't keep his operating.
Both those guys got lucky, very lucky.
