Unfortunately I know of two mid-airs and one ground collision between PowerFLARM equipped aircraft where one PowerFLARM was not operating.

Even when both aircraft have operating FLARM devices, that alone cannot prevent all collision dangers. E.g., once I was circling in a thermal
and all of a sudden my FLARM starting beeping like the end of the world
is coming. The last thing I was going to do at that time was to look at
my gizmos. I looked outside, but never saw the other glider. Thus I
could not take evasive action. No collision, but that was just dumb
luck and moderately-big-sky. I suppose had I looked at the gizmos
earlier I might have seen the other glider on the moving map, so would
have had more situational awareness. The other pilot told me later that
he never got a warning from his FLARM.

Seventeen pages to tell me not to run into another aircraft.

"Maybe strobe light in the nose and tail (or top and bottom), with the relevant lightelectrical engineering skill set is more suited to jump starting a car. There are lots of LED flashers used on Law Enforcement and Emergency vehicles. They seem to be small enough, bright enough and inexpensive, but I do not know whether they are as

Wings and Wheels carries exactly what you are describing:

These are very bright, are integrated with Flarm and will deplete your bank account in an impressive manner.
I have seen a few of the red, forward flashing canopy strobes in flight, and they definitely get your attention. The cost is pretty prohibitive, but it is a well thought out system. I'd love to try to develop something more affordable, but my

Martin-printed shield also minimizes annoying canopy reflections. I also like the skyflar strobe, but it needs better streamlining for external use on the fuselage. I can't comment on the SkyView as a controller, but I am inclined to choose the control box for
The Xprite looks like it would do the job, but it is WAY too big for the cockpit of a glider, at 10 inches by 5.5 inches by 3.5 inches. The Softecc canopy flasher is a nice, small package that doesn't impinge on the pilots' forward view. The custom 3d
The custom 3d printed shield also minimizes annoying canopy reflections.The directional lighting is only so helpful based on what I see from TG. An omni directional strobe is the best choice.
Ugh. Another midair this weekend involving a P-63 and B-17. So tragic.. a lot of cases where see and avoid simply doesn't work, ..as we all know.What was surprising about this accident is that there was no altitude HALO for each aircraft within the airshow airspace. The B-17 was operating at say 1000 feet and the P63 should have been operating no lower than say 1300 feet separating each aircraft

Definitely a tragic situation.
The flight path made seeing the bomber thru the fighter's belly near impossible.
We will have to wait and see what the separation plan was and where is was violated.
Flarm or something like a rear view camera looking down might have provided an extra level
of awareness to prevent this, but ideally not flying into a situation where you need to
see thru the belly...
Is a gaggle a related flying situation? There are unseeable folks under your belly. It
only works because of trust that all are following the plan.
I appreciate Flarm the most when there are gliders behind or below me in a gaggle.

Hi Eric, can you explain more what you look at? In a gaggle I try to look out not in, and find Flarm more of a distraction. It takes me too long to tell from Flarm what glider is causing Flarm to get excited.

behind me or below me, but Flarm shows me where they are and the clearance I have. So,
instead of twisting around in my seat or maneuvering to see gliders that might be in those
location (both of which only work some of the time), I can glance at the Flarm screen.
That quick glance lets me spend more time looking ahead and to the sides, where I can
actually see gliders and track them.
I also have some trouble finding the threat when Flarm warnings begin.

Thanks, I'll try again next season - obviously that needs you to be well zoomed in. Incidentally, I had a mid-air in 2003 joining a thermal - I and the other guy both parachuted and were unhurt. Flarm would almost certainly have prevented it - we had

Yikes, a double bail out! I'm glad it ended well, and once again, I'm amazed at how well
our parachutes, even with untrained users, work if we get out of the glider.
I zoom in to 1NM or less on my small rectangular Butterfly display when near other
gliders, and use the zoomed out (20-40NM diagonal) display on my flight computer to track
gliders that aren't near me.
