Hi Bob II,
I misunderstood; thanks. The IFD 540 is great. So far mine has been flawless as has been the Comant GPS/COM antenna and the AXP 340 integration. Really pleased at this point. I hope Avidyne can build some momentum. Jim |

Simpson,
Something I did notice, while it may be minor, using the WOW from the IFD540 causes the XPNDR at boot up to go in-air for approximately 24 seconds until the IFD540 finishes booting, at which point the XPNDR jumps to GND. I dunno what problems that will cause at a large airports with ground radar or ground based ADS-B solutions. As I type this I realize, while I can't confirm how mine was wired, but wouldn't using a "Low when Ground" make the failure mode to take the XPNDR to GND mode on an IFD failure? Ryan |

Hi Jim-
Anything you find out is welcome, especially if it may indicate that I am not looking at the latest manuals. My question is not with the actual wiring, but with the setup of the AXP340 in terms of properly interpreting the weight on wheels signal from the IFD540. I hope that you are continuing to enjoy your new toys. I think we are on the home stretch. Regards, Bob

PS. I'm waiting for the release of the MLB100. If it produces aural warnings (e.g., "traffic, 12o'clock") and displays weather and traffic on the 540 that is probably the way I will go.
I wish it were dual band ADS-B In though. |

Bob II,
I thought I saw updated info. on the weight on wheels wiring to the 340 in the IFD 540 Installation Manual. I'll check when I get a chance. I remember thinking the 340 manual was outdated. Regards, Jim |

Hi Simpson-
Thanks for working to get the STC documentation up on the website. While looking to see what was out there, I came across a draft of the AXP340 Installation Manual for the STC installation with an approved position source for ADS-B. While perusing that manual, I noticed that Table 13 in Section 7.5.6 does not actually specify the weight-on-wheels configuration to be used in the AXP340 when it is connected to the weight-on-wheels output of the IFD540. That is, is the IFD540 weight-on-wheels output "low when ground" or "low when airborne"? I suppose this will be obvious when both units are installed, but it would be nice to have complete configuration information for the two Avidyne products in advance. Can you check into this and let us know the answer? Thanks. Bob Siegfried, II |

(AXP340 ADS-B STC Status Update - 3 Apr 2015) FAA handler just told us, he"should be able to get us the certificate next week" about 45 min ago. I'm optimistic but I'll believe it when I see it. |

(AXP340 ADS-B STC Status Update - 24 Mar 2015)
Just spoke with the local cert office project manager who is running this STC program through the FAA cert wickets. He thought there was virtually no chance for signoff this week. There is some reason to think we might have signoff by 3 Apr but based on historical progress, I'm not terribly optimistic on that date. We'll see. |

(AXP340 ADS-B STC Status Update - 21 Mar 2015)
The FAA analysts finished the review of the compliance data on Friday and they gave their thumbs up to our local FAA ACO cert office. That's the review we've been waiting on for about 6 weeks. Hopefully our local office will now quickly finish their paperwork signoff and issue the STC. Maybe this week? Can't tell for sure at this point but we're told that's all they were waiting on.

Jake, Thank you. Currently my shop is saying they'll be done "early next week" with my 540/340 installation, and they're one of those that is unwilling to activate the ADS-B Out absent STC approval as their interpretation of the regs is that the specific combination STC is required. That's why I've been following this closely; as much as I like the shop I'd prefer to avoid a return trip to activate ADS-B Out. Regards, Jim |

(AXP340 ADS-B STC Status Update - 14 Mar 2015)
Some progress to report - the analyst in DC promises to look at the data on this coming Wed (18 Mar) so hopefully a thumbs up from him will get the local Boston office moving on the signoff and all these various (unwarranted) installer concerns become OBE. |

Good Evening, this is getting totally off the subject of ADS-B so please excuse one more dumb comment. Flying has a safety ratio roughly equivalent to riding a motorcycle. It is not a real safe thing to be doing. We who fly are taking a calculated risk. Nice to try to make it safer, but if you want the highest degree of safety available in aviation, stick to riding the airlines. Beyond that, buy the best toys you can afford, and LOOK OUT The Window!!
Happy Skies, Old Bob

... and look for traffic (ahead) that is keeping the same relative position on the windshield.
But that said, GA aircraft are all but invisible more than 1nm away, even in the best of circumstances. See & Avoid is a worthy axiom, but it falls far short of assured safety.

No Argument with that point. Nevertheless. even the fanciest electronics will not see non transmitting traffic. Your eyeballs can see conforming as well as non comforming traffic as long as you are looking in the best direction. Look where you are going and don't spend time looking for traffic on the black box that is not in front of where you are going! Happy Skies, Old Bob |

I don't think anyone is counting on black boxes to save them. They're just another tool in the toolbox.
After having an uncertified ADS-B transceiver and yoke-mounted display in my aircraft, and having it point out all sorts of aircraft that have come within 3 miles of me without me ever seeing them even when I'm looking for them dilligently, as well as all the times that ATC has called out nearby traffic that I've never seen, it really rams home the point that the the ol' Mark I Eyeball and the prime directive of See And Avoid are not infallible guarantees of safety, any more than black boxes are.

I note with some dismay that many folks seem to be counting on the black boxes to advise them of traffic in the area. We who do occasionally fly airplanes with NO transponder can legally fly in at least ninety per cent of the US airspace below ten thousand feet (even higher in mountainous terrain) and there is no way anyone can see us without looking out the window. I hope none of us get so reliant on panel toys that we quit looking. I like having my new toy to play with, but I sure hope I do NOT let it consume the time I should be spending looking out the window. Remember what happened to Bob Collins when he was showing off his new 430s? 2020 mandates will NOT address that issue. Happy Skies, Old Bob |

+1
Also enabled and checked out 100% per FAA. Don't know what all the fuss is with the installers, guess they are afraid of a FAA audit that they activated something without STC. If you can't wait it is probably turned off in 540 maintenance menu. Pretty simple to turn it on, there by releasing the shop from any action. I also believe it is some what of a safety of flight issue, while not seeing every aircraft out there it does help to see most.

Well, last I checked, I'm not paid by the FAA. ;-) Shops are of course not authoritative in their interpretation either, but it goes for their shop and you have to live with it. In any case, ADS-B is not required, and from what I understand most ATC units can't do anything with the information even if they can now see it, it is just our own impatience with a cool new feature! I am enabled, and did check out 100% at that faa.gov email address. * Orest |

Orest,
Your interpretation of the regs may or not be accurate, but either way is not authoritative. My shop is among those who will install it but will not configure it to broadcast as they believe it has not yet been approved by the FAA. I'm hoping Avidyne gets the STC before the shop completes the installation. |

And to add, the STC is NOT required until 2020. But many installers are nervous about paperwork.

It has a TSO, which is good enough for mode S, Technically you need the TSO
to operate ADSB out. However, according to Avidyne, the STC is imminent

My installer is telling me that there is no STC basis for the 340 installation as simple S-xpdr (NOT ADS-B out). Tell me that is not true!! My a/c is a Cessna R172K.

Still no movement on the part of the FAA. They are waiting on some data assessment from one of their own guys in the DC office and that has not come yet. The local FAA office doesn't know when the data analysis will pop out of DC so we continue to wait. |

My shop turned on the ADS-B piece in September. There are varying opinions on whether an STC is required at this time. I think it will be required for 2020 compliance, but I personally don't think it is now. Regards

The update is there is no update. The data is languishing in FAA hands. We're hopeful something pops out late this week or early next week. Our FAA contact has told us to check back in mid-week this week.
