Narrative:

In completing the load manifest for (air carrier X) flight (#) it requires a process of using a graph with slanted lines and drawing vertical and horizontal lines for each zone. When doing this the vertical and horizontal lines can vary slightly slanted, which will effect where the cg outcome lies. When doing the load manifest for flight (#) the lines may have not been exactly vertical therefore the cg may have been affected by this. I believe this could be prevented if a straight edge was required to be used in completing the load manifest.

Narrative: IN COMPLETING THE LOAD MANIFEST FOR (ACR X) FLT (#) IT REQUIRES A PROCESS OF USING A GRAPH WITH SLANTED LINES AND DRAWING VERT AND HORIZ LINES FOR EACH ZONE. WHEN DOING THIS THE VERT AND HORIZ LINES CAN VARY SLIGHTLY SLANTED, WHICH WILL EFFECT WHERE THE CG OUTCOME LIES. WHEN DOING THE LOAD MANIFEST FOR FLT (#) THE LINES MAY HAVE NOT BEEN EXACTLY VERT THEREFORE THE CG MAY HAVE BEEN AFFECTED BY THIS. I BELIEVE THIS COULD BE PREVENTED IF A STRAIGHT EDGE WAS REQUIRED TO BE USED IN COMPLETING THE LOAD MANIFEST.
