 |
|
Hello,
i am a bit confused as I have a W&B sheet from ZENAIR with a max 30% of MAC (or max 450mm rearward CG) and I have from CZAW max 35% of MAC (or max 525mm rearward CG).
The strange thing is on my 1st 601xl from CZAW it was like the W&B from Zenair.
anyone any clues???
thanks
CH601xl (RTF from CZAW)

The LAA, who usually go OTT with approvals and testing, publish a document called a TAD for all amateur built aircraft. This document has some useful info regarding weights, CoG limits, operating speeds etc. Generally the info within the TAD will have been checked by a thorough flight test program performed on the first completed example of the type to be completed.
For the 601XL see
http://www.lightaircraftassociation.co.uk/engineering/TADs/162B%20ZENAIR%20CH601-XL.pdf
where theCoG range is given as 300 to 520 mm aft of datum (datum is leading edge).
I hope that this is useful info.
Andrew.
