brendanw Posted February 18, 2008 Share Posted February 18, 2008 So, I hope I'm starting this thread in a reasonably sensible spot given that W&B is such an integral part of flight preparation and operations. We're in the midst of our first flight preparations, W&B being part of the picture. May I suggest to the folks who run this site that a section titled 'First Flight Preparations' be added to the main page? Anyway, here's what we have ... We weighed our Cozy IV for the first time this past Saturday and all is well. We came in at 1184 - 592 on the right main, 591 on the left main, and 11 (10 lb nose ballast) on the nose. I'm now knee deep in the W&B Excel spreadsheet that I downloaded from the Cozy Builders site. Our CG is at 110 in, which is right about where it should be!!! Questions: 1) According to the spreadsheet, a setup with a 210 lb pilot, full fuel and zero nose ballast would be beyond the aft CG limit. Putting 10 lbs of ballast in the nose gets you just fwd of the aft CG limit. Is this generally what everyone else gets? 2) If I add a 200 lb co-pilot to the above configuration (10 lb nose ballast), we're fwd of the fwd CG limit, requiring aft ballast. 35 lbs in the "baggage compartment" seems to get us just aft of the fwd CG limit. Again, is this generally what everyone else gets? 3) Assuming the one would need to maintain the aircraft in ground-level condition to fill the fuel tanks all the way up, do you normally stand there and hold the nose down while someone fills the tanks? What's the general MO here? Thanks for your input at this most exciting time!! Brendan and Don Quote Link to comment Share on other sites More sharing options...
