I have found a number of programs that will work out the weights and balances of the 601 XL. But they are all in pounds and mm. Is there any difference in just using Kilos instead of pounds or is there some other formula to use. We have submit our findings to the RAA here in OZ in Kilos and mm

 

 



Thank you

Ian,



A W&B calculation is a measurement of ratios. The weight of four bananas,

one cucumber length from a pivot will balance eight bananas, one half of a

cucumber length from the pivot (assuming the weight of the bananas and the

lengths of the cucumber are similar).



Just use the same parameters throughout the calculation.



Cheers

Ian,

 

 Numbers is numbers.  I used the same spreadsheet to run W&B in pounds and mm (for me); and in pounds and inches (for the FAA). I don't think your program will know the difference, unless you make an issue of it.

 

 Of course, your numbers will be upside down  (;>)

Hi Ian,



I'm not sure the responses to your weight and balance question were 

really clear.  I agree with all of the ones I've seen, but they don't 

tell you what to do.



I believe you can use any set of units for your calculations and you 

will still get the correct CG result.  The key is to convert ALL 

measurements to the same new units.  This includes the empty weight 

and moment for your plane and the weight and location of all added items.



Good luck,



Paul

Like others have said, just plug in kilos and mm into the program and  

the result will be in kilos and mm regardless of what the output from  

the program says. If you are using an Excel spreadsheet for your  

calculations, you can change the text labels from pounds to kilos and  

then everything will look right. It won't change the calculations one  

bit.
