    Default Weight and Balance

    Attached is a simple Weight and Balance spreadsheet I put together for my Carbon Cub (SN123 w/ empty weight 915 lbs). The yellow cells are the input cells. I thought some of you may find this useful. I have attached it a s a PDF because I could not figure out how to attach it as an Excel file. If anyone knows how, please let me know.

    Nice work Richard, I had a simple spreadsheet like that for both of my RVs. Once you do a few scenarios you will memorize where the limits are, but this a great tool to use to get you there.

    .xls file attachments were not on the "approved file type" list. I went into the admin module and added it so you're good to go if you want to repost the xls file.

    Randy, add .act files to the list and I will upload my FliteStar aircraft file for the Carbon Cub.

    Consider carboncub.act version 1. I have not adjusted performance data to account for +/- ISA temperatures.

    My current problem is to find a way to operate my airplane close to the POH cruise and power numbers. I definitely still have more calibration to do. Here is a screen shot where I set the RPM to 2130 close the the maximum cruise RPM limit on the placard for 2,000' which is 2150 RPM. I also leaned to 50 degree ROP. I just finished calibrating my fuel flow so I think it is right. The Dynon says I am developing 37% power, but the fuel flow is 6.2 GPH. (BTW the oil temperature in this shot is higher because I had tape over 1/3 of the cooler).



    The POH cruise table says at 2,000' and 2150 RPM I should be doing 89 mph TAS and burning 4.4 gph @44% power. I have 26" tires on the airplane and I am going 96 mph TAS as you can see in the screen shot and burning 6.2 gph indicating 37% power. So something is not right. Could be the RPM is not calibrated. I have not found a way to calibrate RPM in the Dynon.

    Anyone have ideas?
