bholleran Posted November 11, 2011 Share Posted November 11, 2011 I have recently been looking into getting a new reserve and would like some help understanding the certification. If you look at the following link it might help to understand my question. http://www.apcoaviation.com/products.asp?section=emergency&product=mayday Extract is this. SPECIFICATIONS Mayday----Area [m2]--Gores-------Weight [kg]-----Sink Rate [m/s] -------Max Load [kg]--Certification 16_______23_______16_______1.863________6.3 (at max load)_____106__________DHV 18_______30_______18_______2.220________5.4________________120__________SHV 20_______37_______20_______2.690________5.4________________160__________AFNOR/CEN Bi_______47_______18_______3.250________5.4________________200__________AFNOR This is a particularly odd example. Can someone please explain the different standards to me. As I thought that the afnor standard was normaly used at 75% of the max load to get the correct usable figure. So in the above example the bi on the old afnor standard would have a 5.4 m/s at 150 kg. And a 6.8 m/s at 200 kg as that was the rate that was used on the afnor standard. I thought that the afnor/cen was the new afnor standard and that the 160kg was the tested figure and gave a genuine 5.4 m/s. If this is the case then it seems wrong that the the bi is less than the 160 given the extra meterage of the canopy. And I have no idea about the other two standards. Please note it is not just about this reserver it is more the standards so that I can get a true like for like comparison. Thanks Barry Please help.
