Yes, at a minimum its unclear what they are trying to convey and certainly misleading. Im always suspicious when the axis labels are missing units (Time is in.Time units). It looks like the marketing department took control of the web page from the engineering staff.

After going thru major fixes on my Tailwind I had a couple of test flights to check things out. I took a look at Flightaware.com to see the flights and they came up but the airspeeds were very erratic. Positioning/tracking looked great, just airspeed was crazy. I decided to pull an ADS-B report from the FAA to see what that stated. They came back with no report found on either flight. They suggested I send in the GPS/Transponder for repair. Any thoughts on what would cause the FAA to throw out a flight, ie: not create a report. I don't have the detail on what info is broadcast on ADS-B so maybe someone might know of a document that explains the process.

Is it erratic in flight? If so, then it's probably a GPS problem and the transponder is just sending out the bad data that it's receiving. If that's not it, then you might try a couple of things. First, make another flight, being sure to climb to at least a few thousand feet, fly a few straight legs of several minutes each, and talk to ATC to confirm that they can see you and are receiving all of the ADS-B data that they normally expect. If ATC reports a problem, or you still can't get an ADS-B report from the FAA, then go to the nearest avionics repair station and get the transponder tested. Only if those two things show problems would I remove the transponder and send it for an expensive repair.

Of course, I've been less than impressed with EX since they 1st started hyping their stuff on the VAF forum; it was obvious that their spokesperson knew a whole lot less than they pretended. 1st question about the graphs in question: Why is the supply voltage changing, if we're talking about an aircraft (or car, or motorcycle, etc) charging system? If properly sized, the alternator output voltage isn't going to vary in normal operation. Makes me wonder if they were really trying to show the relationship between charge voltage and charge current, which should have been plotted as x/y, without time on the graph at all. -------- Charlie Read this topic online here: http://forums.matronics.com/viewtopic.php?p=511168#511168 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
