How does that actually perform when you are = in a valley somewhere? I used to have TIS-B. I loved it when and where it worked but there = were enough discrepancies + the fact that you had to have line of sight = to the Radar facility that I was really enthusiastic about getting my = ryan 9900BX. The very best thing about TIS-B is that it showed me how = much traffic I wasn't seeing. However, the delay and coverage issues = are real. One incident I had, I was at the range limit of the = Sacramento facility when I saw a blip at less than two miles 10 O'clock. = I looked up and there was a mooney headed straight at me. I dove to = the right and no sooner than he had passed my tail, he disappeared off = the screen. If I had been a mile further south I never would have seen = him. Another incident: as I was going into Palo Alto I had several = targets coming up at me. One was 12 O'clock and reported as 300' below = me and climbing. I was about to climb when I spotted it already above = me. That is where the delay was really a problem. Dico, IMO in a IVP you will be very happy to have an active system like the = avidyne TAS 600 or 605. The former is only $8490 and you can install = it yourself. The latter list is a little over $10,000. (You can = probably find it cheaper....or you can find someone who is gaga over = ADS-B and make them an offer....) You'll find it works much more = reliably, regardless of geography and doesn't have the delay of going = through a ground station. The 600 gives you coverage up to 18,500 above which you have radar = separation because you will be IFR. http://www.avidyne.com/products/tas600/index.asp http://www.avidyne.com/downloads/brochures/AV645_Retail_PL.pdf Colyn On Jul 16, 2012, at 10:09 AM, Sky2high@aol.com wrote: Dico, =20 For the present and future, consider ADS-B. =20 Here is an example: =20 http://skyvisionxtreme.com/ =20 Scott Krueger =20 In a message dated 7/16/2012 7:13:32 A.M.
