kgassmann Posted November 6, 2012 Report Share Posted November 6, 2012 does anyone have a good spreadsheet for calculating weight and balance or could provide me with examples? Thanks. Link to comment Share on other sites More sharing options...
Flying Bozo Posted November 6, 2012 Report Share Posted November 6, 2012 Go to http://www.skybound.nl/cgi-bin/service/wb/index.cgi and put in your specifics for your plane and you will be amazed at how it works. Larry Link to comment Share on other sites More sharing options...
Doug G. Posted November 6, 2012 Report Share Posted November 6, 2012 Or, do a search for "Weight and Balance" on this forum and you will also find some examples. I use one provided by N9922Z that works very well once I put my info in. Link to comment Share on other sites More sharing options...

FastEddieB Posted November 6, 2012 Report Share Posted November 6, 2012 does anyone have a good spreadsheet for calculating weight and balance or could provide me with examples? Thanks. By all means use a good spreadsheet if you can find one. Probably very good examples already given here. But if you know your way around any spreadsheet program, there will be benefit in rolling your own. Start with weight x arm = moment, dividing by 1,000 (or whatever) as appropriate. If you do come up with one, review it carefully, and maybe even post it here for error checking. Good luck! Link to comment Share on other sites More sharing options...
Runtoeat Posted November 6, 2012 Report Share Posted November 6, 2012 Here's a link to my spreadsheet "N9922Z" referenced here. I made this when I originally purchased my CTSW but it can be modified to work with just about any aircraft. Go to "tools" "protection" and select "unprotect sheet" to unlock the cells. The parameters of the sheet can then be changed to match one's aircraft weight, etc. N9922Z W&B worksheet_100210.xls Link to comment Share on other sites More sharing options...
airhound Posted November 6, 2012 Report Share Posted November 6, 2012 Weight and Balance relative to legal flight. Regarding required onboard Weight & Balance ARO(W) documentation....Is it a W&B data sheet found in the POH or Logbook with builders info, or must on do one for each flight? Which one is it that the FAA courtesy inspector will ask for? Link to comment Share on other sites More sharing options...
FastEddieB Posted November 6, 2012 Report Share Posted November 6, 2012 You need a current, updated weight and balance in your plane. The "Sample Plane" in the POH does not make it. You do not need one filled out for every flight. But in theory you should KNOW that if you did fill one out, you would be within both weight and balance limitations. Here's a "cheat sheet" I use when I have passengers (for my Sky Arrow, but you get the idea): All reasonable loadings result in a CG within limits. Good news is I'm now closer to 183 lbs, giving me a little more "wiggle room". Link to comment Share on other sites More sharing options...

Scrapman1959 Posted November 18, 2012 Report Share Posted November 18, 2012 Hey gassman, been away from the site for awhile. If you still want a an inflight adjustable radiator cover send me an e mail at Fred@ccrrecycling.com I guess that goes for anybody else too.

coppercity Posted November 19, 2012 Report Share Posted November 19, 2012 Anyone know what regulation states you need to carry a weight and balance in your aircraft? I know under preflight action you need to know the gross weight, but can't find where it's required to be in the aircraft. Link to comment Share on other sites More sharing options...
CT4ME Posted November 19, 2012 Report Share Posted November 19, 2012 any help here? http://www.askacfi.c...-w-in-arrow.htm Some have said w&b must be figured before flight, but paperwork isn't needed in the plane... wouldn't POH have w&b info in it? tim Link to comment Share on other sites More sharing options...
FastEddieB Posted November 19, 2012 Report Share Posted November 19, 2012 Remember that CFR 91.103 has an all-inclusive "gotcha": Each pilot in command shall, before beginning a flight, become familiar with all available information concerning that flight. (bolded mine) If you came to grief on a landing and the aircraft was found to be either over gross or out of limits, I think they could hang you on that one. If you were within limits, I still don't feel that carrying a computation for a particular flight is necessary. What is necessary is that the pilot is familiar with all normal loadings and what it takes to get out of limits. Link to comment Share on other sites More sharing options...
airhound Posted November 20, 2012 Report Share Posted November 20, 2012 I think it takes a little more than showing specific aircraft POH W&B data and guesstimating your load factors and CG verbally infront of an inspector, or even an instructor during a BFR or training. At the very least, to be convincing a pilot should be able, without hesitation, to demonstrate the process followed to derive the particular flights W&B. So its about methodology; do we just whip out our precalculated/templated cheat sheets to show the FAA Inspector, during his courtsey inspection, the specific load data for PAX, baggage, and fuel that our particular flight is based on in the template? Or, why not just do it on the GPS Wt and Balance Ap during flight planning/preflight, and show him that you did do diligence. But I think the cheat sheet method, since its paper, should work as long as it represents the loads fairly close to the particular flight. Has anyone undergone a Courtesy Inspection?

FastEddieB Posted November 20, 2012 Report Share Posted November 20, 2012 Has anyone undergone a Courtesy Inspection? If you mean "ramp check", I've had exactly one in 35+ years of flying. It was at Ft. Lauderdale after returning from the Bahamas and going through customs. IIRC, they just wanted to see the aircraft's registration and airworthiness certificate, and my license and medical. Not a big deal, unless you don't have one of the required documents, of course!

Ian Posted November 20, 2012 Report Share Posted November 20, 2012 Here's one I put together for the CTLS - a bit of a hybrid with weights in lbs but volumes in litres - be grateful for any comments. Cheers Ian CTLS_wb.xls Link to comment Share on other sites More sharing options...
207WF Posted November 28, 2012 Report Share Posted November 28, 2012 To me, the practical thing is mostly weight. Fuel fuel plus how much? (376 # in my bird). Less the weight of all the stuff that lives in the plane (take it out and weigh it. 43# in my case). Then, if the humans and bags weigh more than #333, how much fuel do I have to leave behind? In the CT, the more you load the more aft the CG tends to go, but it is almost never out of the envelope. If it gets close, move some heavy stuff from the bag bay to under the seats or in front of the rudder pedals. WF Link to comment Share on other sites More sharing options...
paul m Posted January 8, 2014 Report Share Posted January 8, 2014 While I was waiting for my Jubilee to arrive I went searching for useful IPad apps and found this one for W&B. Aviation W&B its called. Easy enough to set up a template for your plane. What I really like over an excel solution is that you can do it on your iphone or ipad right at the airport, see the results real time and also email a copy to yourself of the output. I thought the 10 bucks was worth it for these benefits. I know Fltplan.com's mobile app now does this as well (and is free but they need to set up the template for you). Here are some screen shots. The last one is what the emailed output looks like. Link to comment Share on other sites More sharing options...

I think there is a built-in profile for the CTLS, I just modified it to match the W&B numbers for my CTSW. I think the app costs $10...well worth is and much easier than futzing with spreadsheets, IMO. Link to comment Share on other sites More sharing options...
paul m Posted January 8, 2014 Report Share Posted January 8, 2014 The template that was there needed enough changes for my plane that I just decided to create a new one. I submitted it for sharing. Not sure how long that takes. I agree. $10 bucks is worth the convenience and features. Link to comment Share on other sites More sharing options...
S3flyer Posted January 8, 2014 Report Share Posted January 8, 2014 I put together a spreadsheet (sorry Andy ) for my Sting and quickly discovered that was no way to get the Sting out of CG. I varies fuel, co-pilot and baggage and I was still safely in the envelope. I had to go 2x baggage, empty fuel tank and throw in a 230 co-pilot to get 0.2 inches aft of CG. In short, the only thing I do now is mentally determine the weight and I'm good to go provided I'm at a legal weight. Just curious, is it practical to get a CT out of CG?
