Phil C6 Posted December 21, 2020 Posted December 21, 2020 (edited) Hi, in the past the explanation of some players about chaffs effectiveness was chaffs are not very effective because it lost speed very fast... Ok, but at high altitude wind can be very strong and while beaming the speed of the cloud of chaffs could be faster than the closure speed of the agressor and defender (and maybe enough fast for don't be filter by the radar?), so the chaffs cloud must be visible on the radar no? DCS take the wind in consideration about the chaffs? Best regards Edited December 21, 2020 by Phil C6

They'll still fall out of the res cell of the radar very quickly, they could still be filtered out with range gatting. They'll still take a few seconds to fully bloom to their maximum RCS size after deployment. After which they'll disperse slowly over time and lose their effectiveness. Not only that but the resources (not to mention having an accurate picture of its rcs) to keep track of the chaff for more than say 5-10 sec after deployment may not be worth it. Not to mention that the wind would have to be quite quick, even more so if its not blowing right at the targeted radar. Plus the kinds of altitudes were talking about may be quite high (highly variable though), for example chaff heading directly at a radar with a fictional 55kts notch. Over georgia right now the altitude where the winds are that fast is in excess of 18km. A few areas (DCS wise) like a few sections of the central US and most of syria that altitude is much lower (as of this post) is only ~6-8km (is probably highly variable though). But if its even at a 45° angle the necessary wind speed would have to be doubled. I think there are bigger fish to fry before doing this but again may be worth investigating sometime in the far future. Edited December 23, 2020 by nighthawk2174
