CARP - Continuous Analyzer of Radio Performance, automatically calculates and integrates the FLARM radio range over time. More information is available in this blog post.
Since CARP integrates the data without any time restriction, it has to be reset manually when needed. If the data collection period is too long, a recent degradation in the installation quality might not be visible. It’s advisable to reset CARP at least once per year, e.g. during annual maintenance, after the old CARP data (latest IGC file) has been read out and retained. CARP is normally reset using the connected FLARM Compatible display. For displays that don’t have this capability, CARP can also be reset using the Configuration Tool. To avoid reconfiguring the device, a config file that only resets CARP can also be downloaded here.
CARP is available in all PowerFLARM-based devices which have firmware version 6.80 or above.
