What if FLARM were to integrate with ADS-B out. This box would use the existing FLARM technology to determine conflicts and to display proximate targets with other FLARM equipped gliders and not use that glider's ADS-B signal.. FLARM is better for glider to glider collision avoidance. If the glider got out of FLARM range the box would automatically start using the ABS-B technology. The display of this glider might change to a different color on the display as is goes to ADS-B. All aircraft with ADS-B and no FLARM would be displayed all the time at any selected range.

Okay, I know that there are technical difficulties and enforcement issues. Here's the question:

Would a competition mode that allows unlimited range and just doesn't display FLARM equipped gliders that are more +/-1000 difference in altitude be acceptable? If you need +/- 1500 ft okay.

Again, outside of FLARM range (6-10 sm) ADS-B picks up and displays everything for this glider. Non-participants with ADS-B, especially powered traffic is always shown.

Technical issues aside for now, doesn't this give plenty of collision avoidance and also work as a competition mode.
