The Basic Empty Mass (BEM) and the Basic Empty Mass Center of Gravity (CG) position are typically noted on the aircraft weighing report. This report is prepared after the aircraft has been weighed, and it provides important information about the weight and balance of the aircraft. The information from the weighing report is used to calculate the weight and balance for each flight, and this information is typically recorded on the load and trim sheet. So, while the BEM and CG position are not directly noted on the load and trim sheet, they are derived from the information on the weighing report and used to complete the load and trim sheet.
