The >10 rockets, 1.5x altitude rule is for model rockets, not HPR. For HPR, it says "When conducting a simultaneous launch of more than one high power rocket I will observe the additional requirements of NFPA 1127." Personally, I think that is bad wording, since most people (including myself) don't know what NFPA 1127 says. It seems like a safety code should be self contained. Luckily the new rules don't take effect until August, so we will all have time to break out copies of NFPA.

Nope. The change is to treat mass launches of that size as if they are complex rockets on terms of standoff. This does not alter the range sizes (different table) which is where the 1/2 the maximum altitude rule comes in.Since ROC's range layout already accounts for complex rockets, this doesn't really affect us.During our stand down period, the ROC board is reviewing our range layout and procedures to continue our safety focus.Allen Terseness and mis-spelling courtesy of my iPhoneOn Apr 20, 2012, at 3:07 PM, Wedge Oldham <wedgeoldham@xxxxxxxxx <mailto:wedgeoldham@xxxxxxxxx>> wrote:So Goblins on Ks with an expected altitude of 10k need to be setup 15000 feet from the flightline?!?!?On Apr 20, 2012 2:53 PM, "David Erbas-White" <derbas@xxxxxxxxxxxxxxxx <mailto:derbas@xxxxxxxxxxxxxxxx>> wrote:Don't know if folks have seen it yet, but as of this summer the new guidelines for mass launches (anything more than 10 rockets) simultaneously means the stand-off distance is 1.5 times expected maximum altitude (NAR rules, but drawn from NFPA, so I would expect TRA to follow suit if they haven't done so already).
