Had lunch with a high school friend of mine a month ago. He’s been flying for some 45 years. Suggested I get ADSB so we could, along with some other folks, fly to areas inside of Mode C around the East Coast, where we all live. So, I picked up a uAvionix skyBeacon. That being the least expensive way to get ADSB, I felt. Now, all this time later I still have not passed a single FAA PAPR flight test. Failure to pass the test means your system is not in compliance as far as the FAA is concerned. Hundreds of dollars in fuel and some dozen hours of flight time… all for nothing. As it turns out, the first unit was defective. Only after many emails to tech support (they were not taking calls as they were at some aviation event) and several hours on the phone with them later on did they suggest I return the unit for a new one. That solved one issue. The missing altitude output. I still was failing what is called NIC and NACp on every flight. As I have since learned, this has to do with the skyBeacon’s GPS reception failing or dropping out during some portion of my flight. If it does at all, you fail the PAPR test! With the help of my high school buddy, who happens to be a top avionics service technician, and another flying buddy who is an electrical engineer at a major defense aviation manufacturer…. We came up with the reason for the failures. The GPS receiver in the skyBeacon is not up to the task nor is it installed properly within the unit for adequate reception. We did come up with a potential fix and, so far, it appears to work. Had breakfast with my former CFI. Some 38 years of flying. Also has the skyBeacon on his Cessna 172. Flys all over the coast doing these medical “angel” flights for folks who need fast transportation after an operation or procedure. Asked him about any issues with his skyBeacon. He said, “nope, works fine”. I ran his tail number and he’s failing just as I am and he does not even know it. Avionics shops do not want anything to do with this device. Two shops in my area said they do not install them or service them. The idea uAvionix has put forth that the average A&P can verify this is working in 10 minutes is ludicrous. They are deceiving us. One last thought. Once installed, the ADSB must be on all the time you are flying. That is a formal rule. There is a case where a gal with 60 years of flying did a stupid stunt and her ADSB cut out. She lost her license because the FAA claims she turned off the ADSB so as not to be detected. She said she did not but has no way to prove it. Did she or did the GPS fail on her? My advice to anyone looking at purchasing this device to get into ADSB is DON’T!
