TM 55-1520-240-23-11SECTION IIUSE OF FORMS AND CHARTSUSE OF FORMS AND CHARTSG-4. Instructions for use of the forms and charts. There are two parts to the weight and balance problem.First, one must have correct information as to the basic weight and moment. Second, gross weight and balancemust be maintained within weight and center of gravity limits with the addition of load. The first part is controlledby basic weight check list and basic weight and balance record after the basic weight and balance have beendetermined by weighing the aircraft. The second part is carried out on form F with the aid of a balance computer orloading data charts or graphs.NOTEThe DD Form 365-series forms shall have no security classification until filled in. The forms, whenfilled in, shall take on the security classification of the aircraft for which they are used.G-5. Forms. The standard system of intermediate maintenance weight and balance control requires the use ofseveral different forms and shall be presented as samples in this appendix. They are identified as follows:a.Record of Weight and Balance Personnel, DD Form 365 (Figure G-1).b.Basic Weight Check List, DD Form 365-1 (Figure G-2).c.Airplane Weighing Record, DD Form 365-2 (Figure G-3).d.Basic Weight and Balance Record, DD Form 365-3 (Figure G-4).e.Loading Data, Charts and Graphs. Chart E (Figure G-5).f.Weight and Balance Clearance Form F, DD Form 365-4 (Figure G-6).G-6. Record of Weight and Balance Personnel, DD Form 365 (Figure G-1). Listed at the top of this form are theaircraft designation and serial numbers. The form provides a continuous record of the name and grade (civilianor military) of weight and balance personnel responsible for the records, the station, the date assigned, and thedate relieved. All entries shall be complete and legible.G-7. Basic Weight Checklist, DD Form 365-1 (Figure G-2). The basic weight checklist is a tabulation of alloperating equipment that is or may be installed and for which provision for fixed stowage has been made in a definitelocation in the aircraft. It gives the weight, arm, and moment/constant of the individual items for use in correctingthe basic weight and moment on DD Form 365-3 as changes are made in this equipment. When check marks areentered in the IN AIRCRAFT column, it serves as the inventory of equipment included in the basic weight andmoment/constant.a.Inventories shall be made periodically, and when:(1)The aircraft undergoes modification, major overhaul, or repair.(2)The aircraft is received at a new base.(3)Changes in equipment are made for a different type of operation or mission.(4)The aircraft is reweighed.(5)The pilot reports unsatisfactory flight characteristics (tail or nose heaviness).b.The manufacturer of the aircraft placed check marks in the IN AIRCRAFT column to identify the items ofequipment in the aircraft for the delivery condition. This delivery inventory shows equipment included inthe initial basic weight entry on DD Form 365-3.c.Subsequent checklist inventories shall be carried as follows:G-3
