I will check these POH figures against our 172N but presume they will be the same. Can you clarify, in Skydemon there is an option above the envelope figures for empty weight, Centre of Gravity (lon), and Centre of Gravity (lat). Where in the POH link will I find the correct figures and how do these affect the graph itself? https://www.instagram.com/liam548/

Group: Forum Members Posts: 72, Visits: 261	thanks Steve, much appreciated. I will have to look in the POH although as I understand aircraft have to weighed periodically anyway so maybe it is recorded elsewhere. https://www.instagram.com/liam548/

Group: Forum Members Posts: 37, Visits: 157	Hi again Steve I'm afraid that even after a year I am still unable to get to grips with W&B in SD. I have a screen shot of what happens when I enter my details in the report but can't seem to attach it here. is there another way? buy the way when I enter all the weights etc nothing shows in the box. help mogas
