This morning I launched my MA2 from my boat and I was playing around with Focustrack. My Airsense kicked on with a warning that an aircraft was in the area. I shut down the boat and turned off the tracking, and lowered the MA2 to twenty feet elevation hovering next to my boat. I opened the map and saw the plane heading toward me. As the plane got closer the map went from a yellow border to orange to blinking red. By the time the border was yellow I could visually see the plane. It was a sea plane scouting a location to land on the lake I was on. It ended up flying right over me at about 100 feet. The plane eventually landed a few minutes later on the other side of the lake. I wasn’t flying my UAV very high today, but I was very happy I had Airsense. I’m sure it will help in the future as well.

I doubt many float planes have ADS-B transmitters! You were lucky that one did!

That is probably true, but those seaplanes are the aircraft that really need the transmitters. They fly very low in the same air space that many UAV’s are flying.
Agreed, but that is the flaw in ADB-S receivers. The very aircraft that really need them so we can avoid them, like small helicopters, crop dusters, bush planes, private planes, and military aircraft are either exempt, simply don't have them, or turn them off!

I fly most often in a Metro area. It is not unusual for an aircraft, small plane or helicopter to fly over. The ADB-S receivers seems to work fine. I can usually hear approaching aircraft before they appear on my controller with warning (small aircraft image) and yellow border on map. I feel confident in the technology. Have not had one sneak up on me. Enjoy your safe flying.

Like obstacle avoidance, ADB-S detection is a feature, not a guarantee! Rely upon your eyes and your ears first! If you are flying VLOS, it should never be needed, even if it could detect all approaching aircraft. As a feature, at the present time, it is more of an annoyance than a real benefit, which is why DJI lets you turn it off. It's more of a distinguishing marketing gimmick right now, IMHO.
 
I would imagine that all new, or perhaps many new safety features can be seen as a gimmick when they first come out. Too few or too many unneeded “manned aircraft nearby” warnings are a negative for sure. I adjust my warning threshold on the app depending on the airspace that I am flying in and this helps a lot.

But like the OP stated, this helped them in that case for sure. A warning from the app and not just our own senses is an addition that will only get better and better I think.

And BTW, ADSB OUT is required as of the start of 2020 in the cases below regardless of the aircraft type. And yes, there are of course waivers but in general:


“The FAA requires ADS-B Out capability in the continental United States, in the ADS-B rule airspace designated by FAR 91.225:

  • Class A, B, and C airspace;
  • Class E airspace at or above 10,000 feet msl, excluding airspace at and below 2,500 feet agl;
  • Within 30 nautical miles of a Class B primary airport (the Mode C veil);
  • Above the ceiling and within the lateral boundaries of Class B or Class C airspace up to 10,000 feet;
  • Class E airspace over the Gulf of Mexico, at and above 3,000 feet msl, within 12 nm of the U.S. coast.”

But yes, looking at the above, it is very possible that a plane is near you without ADSB OUT In smaller airports or even controlled airports but stay at lower altitudes.


Cheers,

Fly safely.

On a slightly unrelated note. ADSB is a great improvement to my daily life as a comercial pilot. We have ADSB receivers in most of our aircraft, and I carry a handheld receiver as well. ALL of our aircraft have ADSB OUT. I have had dozens of cases where other aircraft have been avoided earlier because of ADSB vs use of just a Transponder receiver.

And I also have had TWO near misses with a-hole drone operators. Both of them were in the So-Cal airspace. Both of them were in the 2,000 AGL range. Both of them within eyesight....so pretty damned close.


Fly safely everyone
 
I've been I guess Blessed where I live and fly have a few small airports and a lot of choppers I have say in the month I've been flying the MA@ 95% of the aircraft I have heard have had ads-b and I knew they were coming long before I heard I love it and hope more manned aircraft start using the hardware..

ADS-B was required for all but a limited amount of airspace Jan. 1 2020 for all aircraft. average installation cost. 9000 bucks

This is why VLOS is important. I would never forgive myself if I brought down a plane causing casualties with my drone. I’m told that many small aircraft don’t have the technology to broadcast the signal.

That is so true. When flying my MA2 I’m always looking out for any aircraft, but the sea planes can sneak up on you because they fly so low. And if you are on a lake with loud boat engines running, that eliminates hearing the oncoming aircraft. I was very pleased to see how well the Air sense worked, and I’m happy I have it. And it should get better when more Airplanes have the transmitters.
 
Helicopters can sneak up on you too, even when you are flying well within VLOS. Airsense is very useful as an "extra set of eyes" for that risk.

Being aware of surroundings (ground and air) and VLOS of quad is part of safe flying. I can also appreciate the "extra set of eyes".

ADS-B is seen now like seat belts were in the 1960's--a royal PITA. Requiring them by law did little to increase their use. It took an annoying buzzer. Now, nobody in their right mind would drive without them. Same with ADS-B.

Are the handheld units very expensive?

The unit that I have has a ton of features beyond ADSB IN. And yes, it was expensive. I have an older one called the Stratus 2S. But this unit is also used for: Weather info, GPS position, AHRS (attitude) etc etc. It is an awesome unit to have as an aircraft pilot. You need a software to go with it as it is just a box without screens. Again this is a “manned-aircraft” software such as ForeFlight. It’s not really that practical for a UAS pilot as it also is not cheap. (Although I do use it for VFR sectionals lol)


Long story becoming too long....

In review......The stratus is not really practical IMO for the average UAS pilot to add safety to your flights.
 
Are the handheld units very expensive?
Yes! They're about 1K USD, but the fact that they won't have to be TSO'd* by FAA plus economies of scale will make them much cheaper to be factory-built into 2020 and later drones.

* It costs $400 to put a USB charging port in my son's Piper Cherokee. Compare that to the $9.95 to buy one for your home or auto.

The reason I inquired about the price, I was wondering if the average pilot that owns his own aircraft, would it be something he or she would purchase? Maybe so if it is the unit like yours that has more functions.

I do know several pilots that have bought the Stratus 2S (or updated version). But then again, this is only a ADSB IN, not OUT unit. It is for seeing other aircraft and not sending out aircraft position. Adding ADSB OUT to general aviation aircraft is indeed a pain in the butt and expensive. I can see that there are perhaps hundreds of planes out there that have yet to be converted with the OUT units. More than likely way more than that.

I forgot to mention the ability to get updated and precise TFR info from this device. I know that the $1,000 (my original payment years ago) has been well used in charting and avoiding TFR’s. Some of the TFR’s popping up while in flight.

Again, this has kind of spun off topic from the OP. But the Stratus has saved my *** a few times.
