Butterfly display (displaying a big red logo under normal flight conditions)

I have hundreds of hours with transponder and PF without a single false alarm. None of the 50 pilots or so that flying in our region with both PF and transponder are reporting this issue. So it is time for you to conclude this is likely a unique issue with your setup or send your PF to repair.

But are you, and the 50 others you cite, using the PF portable? Not that I suspect there is any difference in this respect.

Did you read the firmware release notes that describe the failure to detect co-altitude targets. If so, why do you dismiss FLARM's own assertion that there is an issue?

Wonderful that you have no false alerts but don't you have any concern that the manufacturer knows that co-altitude targets, the only ones that can hit you, may not be detected?

I know of at least 5 pilots flying with portable and transponder and have no false alerts. I only know one locally who has the same issue. I would also like to hear the response from the factory. It seem that portables have more issues than brick. I recommend people to get the brick.

Thinking again about the displays...

the Portable unit has the large radar screen, with the bottom sliver cut off (and thats ok!) giving good situational awareness (SA) to the sectors of interest, large icons, etc.

The BF display has the complete radar screen, with data to the right. So this display is more setup for a tactical awareness (TA) purpose.

If/When the BF team get around to bringing their products back in-line to each other, it would be nice for the user to be able to select the option of either the SA or the TA display.

I agree with the statement that any rotation of the knob should be first and foremost for zoom levels, rather than target selection.. heck that could be another user selectable feature.

You're just not getting it. The latest firmware fixes the spurious own transponder alerts at the expense of reliable co-altitude alerting. Saying that you have no spurious alerts contributes nothing. Tell me instead about how many alerts you have had for transponder targets that maintained the same altitude as you while in the alerting volume.

If you fly only a glider you may never see this scenario. If you fly a powered airplane then it is not only possible but likely.

Ok, I missunderstood your comment. I suspect this suppression only happens at the exact same altitude consistsntly. I didn't notice targets disappearing when flying together, and I am flying with latest firmware since it was released. I assume their algorithm is smart enough to make it a non issue. Did you experienced targets disappearing when you fly power at the same altitude as other traffic?
