Unfortunately there is a number of collisions in North America between Flarm equipped aircraft where one unit was not on:
- Taxiing towplane with Flarm switched off had propstrike on wingtip of glider that had just landed and pulled in front of towplane
- Fatal midair between towplane with inop Flarm and glider
- Midair between two gliders. One Flarm had expired software.
Range analysis was performed on gliders at the Canadian Nationals. Most were substandard.
