You designed some little tool that was used at a heavy water reactor...I operated a heavy water reactor for 10 years.
Brent, you could save all of us a lot of time, speculating, wondering, concern and doubt if you just came clean with everyone and spell out, in a straightforward and frank manner, who you work for, what your relationships are, what your financial interests are and who you aren't involved with.  Why should you do this....quite simply, when one takes a position is a sordid affair of this matter and imply or state specific, unique knowledge and information and required that everyone else simply has to take your word for it...well, you owe it to people to be straightforward about where you're coming from, what's your agenda and where your conflicts of interest lie. If you are unwilling to do this honorable thing, then limit or eliminate postings that are long on opinions and void of facts.

That dog you don't have in this fight sure barks a lot. 

I will assume you are not the reactor operator that made the "little" mistake that caused the fuel rod to disintegrate that caused the reactor to be shut down that caused rolling blackouts through the capital city of a South American country that my "little tool" was able to clean up in 8 weeks, saving 3 years worth of reactor down time that would have otherwise been required. It was indeed "some little tool"!  In retrospect, it may have been more germane to mention our work with Reverse Osmosis and Ultra Filtration systems used in the batch preparation of dialysate for home hemodialysis machines.

As for your other questions, I work for Regan Designs and some of our clients are listed on our web site. As I said back on 1/6:

"
My company designed the original Sierra Flight Systems IDU-I (hardware, not the software) and built some of the early production systems. We had an ongoing relationship to support D2's manufacturing and service efforts. D2 folded owing us a significant sum. Is the Pinpoint mine? I wish. We did do some consulting. The nature of which and for whom I am not at liberty to say."

As I said back on 1/9: "
we do not receive royalties or commissions from this product. (Pinpoint) "

Regarding "
who you aren't involved with", it is a long list. There are about 6 billion people to consider, plus corporations, government agencies, LLCs...........

It is not my policy or intent, nor have I actually asserted that  everyone "simply has to take my word for it" in matters of consequence. Quite the contrary, I  encourage everyone to do their own research, talk to those with first hand knowledge or, better yet, to acquire their own, direct empirical knowledge. The Experiment Aircraft  category is about education and the best teacher is first hand experience.

Your suggestion that the "honorable" thing for me to do is to disclose confidential information for the sole purpose of saving you some time and wonderment is, on its face, absurd. It only took me a few minutes to discover your company deals in nuclear power plant water quality equipment.  How much time have I saved you by reposting information that was posted on this list 10 days ago and is available on our web site?

The Xbow 42x had a known and demonstrable problem(s) that were (are) related to the GPS and some "power sequencing issues" (per Xbow). It was reported (although not directly experienced by myself) that keying the mike would jam the GPS and cause the AHRS to start rolling. A member of this list reported experiencing this phenomenon while in IMC and, to his credit, declared an emergency and was able to land safely. COM frequency interference is a known issue and addressed by DO160E emission and susceptibility limits. Xbow has claimed to have the problem(s) fixed on more than one occasion only to find out the fix was not in hand. When you combine these independently verifiable facts with Xbow's recalcitrance to answer the "What happens to the 42x when you lose GPS signal?" question, a wise man would want more than Xbows word that the problem is fixed. If it were a certified product we were talking about, the FAA would require comprehensive testing and documentation.  I could be Nic Machiavelli himself recommending that GPS signal loss be tested on the current 42x "fix" and it would be no less a good idea.

If the 42x is now finally fixed then GREAT! Good for them and good for their customers. The last thing anyone wants is to have an AHRS that  rolls over and shakes at the sound of a COM carrier.

My agenda is to improve the safety of as may of my fellow flyers as practical.  I work towards that goal on a daily basis and am currently working on the design of the next generation CFS display system.

I sign my postings with my full and real name and detailed contact information is available on our web site, hardly the act of a devious and secretive person.

As to the heart of your criticism, my ability to keep confidential information confidential, I make no apologies.

As to eliminating my postings on this list, if Marv or others whose opinions I respect suggest this as a prudent course then I will happily comply.

In conclusion I wonder if Chuck sees the irony in his own words. Standing in a pool of information he is as Tantalus, unable to drink the knowledge, but vigorously opines on the excess of opinions.

Reply if you must, but I have said all I should need to say.
