Who here has no need/intention to add ADS-B OUT?

[Tailwind_Fan]

I laugh because my old Tri Pacer has the old ELT on the rear passenger door, and I have no intention of installing an ADSB out functionality on it. I do have an ADSB In stratux that I put together last year. There’s a lot of airspace in Eastern and central California that doesn’t require ADSB, and on the odd occasion that I need to travel into that airspace I’ll use the online access tool.

US transponders use 978 for Mode C hence UAT ADSB, and 1070 is Mode S for that version. That’s how airplanes talk to each other. The gig frequency is the satellite connection. The sat connection with a GPS location transmitted is the functional difference between it and TCAS. The boxes got smaller and cheaper. TCAS was probably $100,000 box when it came out.

Nothing like the ole Atlanta Class B Airspace to keep you on your toes!

Ha. My home airport is a half mile or so outside that airspace. I really, really, need to install the Stratus ESG that's sitting on a shelf in my basement...

You still need a mode c transponder, though. If you already have one of those (I don't) then adding ADS-B isn't that big a deal.

My home airport is just inside the mem mode c veil, if the FAA would have limited it to the class b so I could fly under the shelf, I would not have installed it.

I think the latest from uvionics (or whatever it is) has a transponder included. The unit fits in the taillight socket.

What is this online access tool that can eliminate the ADSB requirement?

One of the Fly Baby crowd just installed one of these. Small control head in the cockpit, combined transponder/ADS-B out in the tail. Sounds like a pretty slick unit. Cost was about the same as my Microair transponder and my Skybeacon installed, with a lot less hassle.

Uavionics keeps stepping the game up.
The UAT uses the 976 MHz freq area for distance measurement by using the DME signals. The 1070 freq area is standard signal and the mode S setups can calculate distance internally. The FAA hoped all the GA VFR would have bought UAT and left the 1070 for the IFR, but gadget hungry, most went all the way. The FAA waver is per flight. There is a page on the FAA site to schedule.

 

[Bill-Higdon]

Because I have family in Canada I would need 1070 Mhz to fly up to visit them and the Uavionics tailbeaconx checks multiple for a very good price

Nice. How close to the river are you?

Normally 1/4 mile but getting closer day by day. Runway may start flooding next week ...

(Second flight this morning of N214FL RV-4 Mazda 13B Renesis (50 min flight). Too over-propped to develop full horsepower and too restrictive openings in/out of radiators (A/C evap cores) for proper coolant flow. I guess they don't call it "experimental" for nothing.)

You will have access to C and B airports by calling the ATC facility and requesting a deviation from ADSB requirements.

You MIGHT be able to do this once or twice, but from what I've read, it you use it to get out of ADS-B you'll get a paddling. It's supposed to be to get to a shop that can install the units. So far I have not heard of anyone getting a nastygram.

I know you can zig zag all over and miss airspace

You might want to look at a map. LOTS of non-ADS-B area out there. I can fly PA->FL and maybe add 50-100 miles to get around a Mode-C veil and some Class C's. Thing is, transit through a Bravo is never a given, even with VFR corridors. And for me, the major PITA is the DC area with its own special rules to transit.

The 10k altitude restriction seems arbitrary, why 10K? Why not up to Class 'A'? Mode C worked fine for decades. IIRC Centers do have *some* ADS-B integration, but that high up Radar LOS should be pretty good.

 

[Marc Zeitlin]

The 10k altitude restriction seems arbitrary, why 10K? Why not up to Class 'A'?...

Because the ADS-B required airspace is effectively the same as transponder required airspace, and transponders are required above 10K ft. (with the 2500 ft. AGL exception).

So if you need a transponder to fly somewhere, you also need ADS-B now. You'd have to go back the transponder requirement setting period to determine why they chose 10K ft. MSL.

 

[radfordc]

I'm thinking...No

 

[TFF]

No because you got them at gun point.

I doubt you'll ever hear of someone getting a nastygram because it's permitted under the FARs.

There are two published deviations in the ADSB reg. One for when your ADSB is inop and you need to get somewhere to get it repaired. The other is for when ADSB is not installed with no limits or limitations on when, where or how often.

Good to know. Thanks.

Is it a Narco?

Sorry Bill for taking so long, but here is what I found out about the transponder in the 150. It's an ARC Aircraft Radio, RT359A, Serial # 414201114, 14 volt. It's original equipment from Cessna I believe.
