If your tactical computer display has good depiction of Flarm and ADSB targets, I see no reason for the dedicated Flarm display. It is simply duplicating what is already in front of you. No extra panel space is necessary, though some space behind the panel is.

Sure there is. The nav computer map display is best set to show (roughly) what you can glide to. The Flarm & adsb targets you care about -- the close ones -- won't be resolvable.

2nd display solves that problem.

Again, if the display has a "good depiction of Flarm and ADSB targets", you don't need the Flarm display in my opinion. Close target are automatically made more noticeable, and very close targets are warned of with audio and graphics. This is *substantially* more obvious on my tactical display than on the Flarm display. A good tactical display will be context sensitive and take care of this for you. It really shouldn't be showing you all the places you can glide to, if you are about to hit a 737.

All modern glide computers with a flarm interface do a decent job of collision warning. I haven't compared them all, but some are quite excellent. That problem has been well addressed in the marketplace.

The problem that still exists is the simultaneous depiction of non-threatening flarm traffic (your buddy at 1/2 mile, seven o'clock) and 30 miles of terrain, your course, alternate landing sites. Modern flight computers give you one, or the other (depending on zoom level). If you don't see that as a problem, never mind! Changing the zoom level is just another cockpit distraction I seek to avoid. All those little seconds in the cockpit add up. I want my eyes and attention out the window.

All of the powerflarm/butterfly display are pretty dreadful imo. Any of the LXNav flarmview series would be preferred for a dedicated flarm display.

Perhaps the easiest way to warn is with good audio.
Do any of the currently available TABS / ADSB-In devices offer audible warnings?
And do they fit in - not hanging off like an afterthought - a typical glider instrument panel?
Possibly the new Air-Avionics unit?
Jim

The Air Avionics vario combined with PowerFlarm does audio warnings very well. As do many other modern combinations. ADSB and Flarm traffic are both warned of: "GLIDER - 3 OCLOCK etc."

As Jfitch noted the air-avionics (Butterfly) does, so do the LXnav 90XX computers, along with spoilers open, gear warning, stall speed, apparoching VNE, final glide, tire pressure low (just kidding with that one)...... Audio warnings for a plethora of items, all possible with the new generation of computers.

Flarm (that is, the company) tells me that it (that is, the powerflarm product) sends warning messages for conflicting adsb traffic on the dataport(s) exactly the same way it does for flarm, but with logic appropriate to power planes / jets / whatever. If that's true, then you as a flarm + CN2 user are covered. You'll get the same "Traffic, 3 o'clock high" message you would get for a glider, but presumably at a much greater distance. Unfortunately (and this is a real aggravation for me) there is NO WAY TO TEST THIS short of jousting with an ADSB-out equipped aircraft.

The CN's audible FLARM warnings are good, haven't done any dogfighting with power planes lately.
The thread is about TABS. Wondering about non-FLARM devices giving useful audio warnings.

You asked about adsb-in...

I can tell you from experience that the Air Avionics vario will warn of ADSB traffic just as it does with Flarm traffic. The audio changes to "AIRCRAFT, 3 O'CLOCK, HIGH etc" instead of "GLIDER". In the Tahoe Reno area we have plenty of passenger jets flying close by to test this....
