Would it not be simpler to just say:
OPERATION USING THE INTERNAL POSITION SOURCE IS PROHIBITED. USE OF THE EXTERNAL POSITION SOURCE IS REQUIRED.

That way everybody could use the same placard. It's not like the external position source is ever going to be different for the pilot. Any changes in the aircraft's future configuration are the responsibility of the maintenance person.

You would have to specify that the external position source is a certified accepted one - either by model number or reference to the TSO covering it.

Placard
 
David,

I agree with your response from a global perspective - mine is being approved as an individual AMOC, not a global one. The Global AMOC, when published, should provide for language for whatever alternative approved devices are connected.

The original language in the AD referred to the only unit type certified to perform this function. Since my individual AMOC seeks to replace that specific device type with another specific device type, the consensus was to specify that device type. The initial discussion centered around entries in the POH - which we are not required to publish and/or maintain for Owner Built and Maintained aircraft so this was the compromise agreed to.

The Global AMOC, when published and accompanied by hardware (added cost) and software (added time) changes may replace the individual AMOCs for those of us that get them - but the individual AMOC provides for immediate post-2020 compliance regardless of further vendor actions or timelines. The individual AMOC may require me to stay with the current software revision until a later one is approved by a Global AMOC or AD update - meaning we may have boxed ourselves in to a corner - but it is a known corner, with known timelines, costs, and features!

This is a great product at an initially great price and I want to use it long-term - without waving my checkbook every time I turn around!

If your external source fails for some reason, would you switch to the internal source, or fly with no ADS-B position reporting? Is switching something that could be done in flight?

Switching in flight
 
Based on the way this system is designed and usually installed, it takes an external computer to reconfigure the GPS source - something that you would not do in flight!

In talking with Bill at OSH, he shared the following:
  1. He has applied to the FAA for a Global AMOC. This has nothing to do with the activities that Ralph and I have mentioned previously on VAF. He actually voiced his frustration that somebody else would submit an AMOC.
  2. He stated he can't sell the new units, upgrades, or release 5.0 until the AMOC is approved by the FAA.

In thinking about our conversation, it started to bug me quite a bit. Bill's comment was why would anyone submit an AMOC independently since he clearly wasn't going out of business. I think that's the perception that he doesn't understand. Due to Bill's complete lack of communications, failure to return voice mail or email. I've had similar issues with Scott Edwards. Since there were no updates for months on end, what other conclusions would a normal individual come to?

If Bill had simply stated that he needs to get a Global AMOC approved, but the schedule is outside his span of control due to the FAA process, it would have most likely appeased most folks. If he was transparent and just communicate what he was working on and trying to get done, most folks to would trust him and extend to him the courtesy of trusting in his efforts. Unfortunately, since he chose not to communicate his direction, intent, or next steps, most folks were extremely frustrated.

I'm share with him my frustration, specifically the problem with the display port 2 not being able to transmit traffic or weather. He stated that would be resolved with 5.0 of the software.

To be honest, I'm still sitting on the fence about proceeding with the upgrades. I've got my unit working with the GTN-650 and an individual AMOC (hoping a Global AMOC coming later). So I'll be compliant soon. I'll have to study the upgrade later to see if it makes sense for me to purchase. My concern would be that if you don't get the upgrade, some future release of the software may not function properly.

I have been watching this from the sidelines still deciding what direction to take. I had originally planned to install the Navworx EXP unit and my normal luck with this sort of thing should have resulted in me sharing the suffering with so many of you. However, for some unknown reason I waited this time...

I have to say that at this point I doubt that I would choose a Navworx product regardless of the ultimate outcome of all of this, and the main reason for that is the inexcusable way in which Navworx have conducted themselves especially in the area of customer communication.

All companies make mistakes. It's what you do after the mistake that separates one company from another.

Along with an airplane deal I wound up with a Navworx -EXP brand new in the box. So, what should I do with it? :confused::confused::confused:

Follow the lead of the manufacturer:
1. Talk as if you know what you're doing.
2. Make lots of promises.
3. Collect money from a buyer, but don't send him anything.
4. After a while, send him the box but tell him he can't use it.

Unfortunately that seems to be the way of things.

I don't have a dog in this fight, I was hoping Bill would pull his head out and save the day for the good of the community, it appears that's not going to happen.
