Why no "situational awareness" (collision avoidance) apps for cell phones?

The ADS-B in my C-180 provides collision warning.Â* Shortly after the
installation I was flying a GPS arc to an ILS (practice approach) when I
got an aural warning:Â* "Traffic 3 o'clock high, 1 mile!"Â* I had been
monitoring the traffic on my tablet, ATC had been reporting each of us
to the other, and I knew I was below the traffic.Â* Since we were both
VFR, no vectors were issued.

My system is a Garmin 430 WAAS GPS and GTX-345 ADS-B In/Out
transponder.Â* Not really suitable for a glider, but great for a light plane.

Can anyone say if a Trig TT22 with TN70 will provide collision warnings?

I understand the differences in gliding and powered flight and while
collision warnings are really terrific, if I had to choose only one, I'd
go for situational awareness.Â* I can easily avoid the more distant
traffic and, if a thermal is too crowded, I'll just go somewhere else.Â*
And, no, I don't do contest flying.

There are a number of other systems that provide peer to peer
communication, PilotAware, ADSB in/out and others. They provide
situational awareness but not collision warning.

The TT22 and TN70 gives you ADS-B Out only, unlike your GTX-345 that does ADS-B Out/In (1090ES Out and 1090ES In and UAT In). Glider pilots would normally get ADS-B In via a PowerFLARM (1090ES In only) or if they have room for a separate display then in some cases a Stratus or Stratux receiver (and if you do that get a dual link receiver).

Powerflarm is not a good ADS-B IN solution. It does not see UAT equipped aircraft, nor does it support ADS-R or TIS-B, which makes UAT and conventional transponder equipped aircraft visible to ADS-B IN equipped AC (as long as those aircraft are also ADS-B OUT equipped).

An ADS-B receiver (SCOUT, Stratus, etc.) coupled with an application like Foreflight or FltPlan Go on a smartphone or tablet provides an economical ADS-B collision warning system for those pilots who have an ADS-B out equipped glider.

PowerFLARM has limitations, but is still likely the most useable/useful ADS-B In solution for most USA glider pilots. Especially those that actually fly with their glider near other gliders. But yes folks need to be aware of the limitations.

As usual, Mike, you are factually wrong.

PowerFLARM most definitely shows ADS-B (Mode S, the most common). It also shows Mode C and Mode S transponders in PCAS mode; and since UAT ADS-B has to be associated with a Mode C or S transponder, it will show them.

Now, again, tell me what ADS-B IN/OUT setup you have in a pure glider - that interfaces with standard glider displays.

Crickets....

Please stop spreading your "fake news" about PowerFLARM. We get it that you don't like it. Get over it. Enjoy your ADS-B whatever and I'll enjoy my PF.

Just stay away from my thermal!

You stay away from his thermal. Least equipped glider has the right of way. Haha.

Least skilled pilot lands first. And you are definitely in the hunt for the least mentally skilled pilot around.

How about you actually reading my posts???? I didn't say that PowerFlarm doesn't show ADS-B traffic. I said that it doesn't show UAT ADS-B traffic. Nor did I say that it did't show transponder traffic. I said it didn't show TIS-B traffic.

Supporting TIS-B improves the situational awareness in regard to transponder equipped aircraft orders of magnitude better than the PowerFlarm PCAS type transponder detection. PowerFlarm can't give you any hints on where a transponder equipped aircraft is (behind you, in front, to the left????). The range is a very crude approximation based on signal strength. The only thing it can tell you pretty accurately is the altitude of the transponder aircraft.

An ADS-B receiver that supports TIS-B will show you exactly where a transponder equipped aircraft is, to the same resolution as is visible on ATC radar. This of course assumes that you are within range of an ADS-B ground station and that your aircraft is ADS-B OUT equipped.

Mike, unlike you, I can read and comprehend. Your posts about Flarm are factually incorrect. You don't like Flarm, OK, don't use it. But right NOW, ADS-B is pretty much a non-player in the glider market. Again, tell me what YOU use in your pure glider?

Yesterday my PF was happily showing me airliners, commuters, and VFR traffic (via Mode C PCAS). No UAT? So effing what - UAT has to have Mode C or Mode S - and I see that. And what is the fleet implementation of UAT - or Mode-S ADS-B out - in the aircraft ACTUALLY FLYING RIGHT NOW? 20%, max?.

Hey, if your ADS-B in/out gives you warm fuzzies, great! Me, my PF gives me what I need, right now. In a few years, there may be a suitable ADS-B Out solution that I will get. Who knows. But the trash you are putting out helps NO-ONE.
