WIlliam inputted the test strikes and it displayed correctly on the Garmin 430 and incorrectly (180 degrees out) on the Chelton. I am running 5.0. There was no overrirde of mag heading or anything like that as I was the person doing the manipulation of the knobs on the Garmin. Be that as it may, no matter what the problem is-- hardware-- software or whatever, the Chelton is displaying stormscope strikes incorrectly and I concur with Hal, in that we need to be very careful relying on stormscope/ Chelton information until this problem (on more than one aircraft) is researched and resolved. I appreciate William's and L3's hard work this weekend at the Lancair flyin trying to resolve Stormscope issues and your looking into this matter further. BTW, I do suspect 5.0 at this time as I have had an opportunity to observe lightning strikes and not see anything on the Chelton at the expected range and bearing... just my 2 cents. Regards, Jeff Edwards [ first, I've not hear of any issues... (other than skin map pains) if the wx500 gets heading from a gps, and you are on the ground the heading will be 0 or gosh knows what if the GPS is chasing selective availability ... the correct way to wire the wx500 is to the EFIS as it has a real heading, not gps track... (plus it makes the strikes really zip around when you are on the ground about to make a stupid flight) heck, if its ok on the 530 and bad on the CFS, you KNOW its a heading input problem... anyway, go into CFS maint mode and bring up the test wx500 page, and it has a cell quadrant test.. that will tell you for sure if its working.. as for the heading from gps or efis, well, look at the jumpers and wires going into the wx500.. email me if you want the wiring docs.. I can't imagine an issue, but this seems to be a hot one, so I'll just sit back -Rob ]
