Weight And Balance; Table 4-12 Weight And Balance Calculation Example - Garmin GI 275 Installation Manual

4.8 Weight and Balance

The aircraft weight and balance record must be updated after the GI 275 system is installed by following
the procedures typically detailed in Section 8 of the aircraft maintenance manual. Practices defined in
Chapter 10, Section 2, Weighing Procedures, of AC 43.13-1B Aircraft Inspection and Repair are
acceptable.
The aircraft Equipment List must be updated to include items that are added, removed, or relocated. The
updated list must be dated, include the name (and certificate number) of the person that updated the list,
and be retained with aircraft records. A sample calculation is shown in Table 4-12 below.
