As I come close to my SR20 delivery, I have started looking closer at the usesful load capabilities. This has entailed looking at the CG tables in the POH, as well as phoning an “in the know” individual at Cirrus.
My conversations with the individual at Cirrus lead me to believe that they are very optimistic about getting a 100 pound increase in total weight (taking it up to 3000 pounds)certified in late spring.
Looking at the going rate of 2050 “bare”, adding stormscope, 3blade, C configuration, and leather, it brings it up to the 2100 pound range. This is close to the 2100-2117 pound level that has been reported on this great web site.
Taking the 2117 pound / 296069 moment example of one recent production airplane, it brings up some important issues, I think. First, the useful load full fuel is 447 pounds without the max weight increase, and 547 with it. Looking at the 447, it appears to be even less that that, because I think that if you put heavy people up front (200 pound pilot, 225 pound co-pilot, for example), you have a CG problem that has to be remedied by putting weight in the back. This, of course, further reduces the useful load.
The max weight increase will be a huge help, not only because of the weight increase, but also because using all that weight would presumably be taken by baggage or a rear seat passenger, either of which addresses the CG issue. On the other hand, if the max weight is not increased, carrying two big people in the front can be a problem, as it appears to me.
Anyone else have any experience in dealing with this issue? Am I correct in my computations? What are the experienced current owners doing about this.
I’d very much appreciate any input. Also, I’ve done what I think is a pretty useful Excel spreadsheet that helps analyze this, and would be happy to send to anyone interested via a return to e-mail.
