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.

best,
