Hal,

I have contacted the software team at Chelton and will let you know = the=20 outcome asap. I will tell you that I haven't heard of any problems = with=20 the stormscope displaying properly due to software. Any and all = problems=20 have been either installation related and on two occassions the WX-500 = was=20 defective. Usually, it is mis-wired or the jumpers haven't been = set=20 properly on the WX-500.

Chelton has, in fact, passed the full level of L3 qualification = testing=20 with the the L3 Stormscope. This testing was extensive and was = performed=20 at L3's engineering facility with Chelton's software = team present last=20 fall. There is nothing wrong with the display of strike data on = the=20 Chelton system and it has been approved by L3.

I suspect the = field=20 service tech from L3 was having trouble running his test set. The=20 stormscope sends strikes with a heading parameter when installed = properly and=20 with the proper jumpers in place. The heading parameter is the = heading the=20 strikes are relative to. If the stormscope has valid heading info = (from=20 one of several sources, including the EFIS), then the strikes come in = with a=20 proper mag heading attached to them. If the stormscope has no = heading=20 info, the aircraft will use its own heading to display the = strikes. This=20 is correct operation. I suspect he has overridden the stormscope's = source=20 of mag heading or not provided the proper input from his test set for = mag=20 heading. It is unfortunate that William jumped to conclusions and = condemed=20 the improper operation of your Chelton instead of discussing = his findings=20 with his co-workers back at L3.

In any case, I am double checking everything with Chelton to verify = everything on our end. Also, I spoke to a customer Sat. evening = just=20 before I left the fly-in that has the WX-500 hooked up with his Chelton = and a=20 MX-20. He has over 200 hours on the system and verified that when = he=20 receives strike information, it displays (correctly) on both displays in = identical quadrants.
