5	Instructions:
6	Enter data in the yellow cells only
7	Enter Pilot weights in either lb or kg - not both. If both fields are used it will default to the lb column.
8	If a data cell turns red, you have exceeded the maximum allowable value for that item
9	If the Total mass and CG location cells are green it is safe to fly. If they are red it is not safe to fly
