WEIGHT AND BALANCE HANDBOOK is the primary tool utilized for what?
Maintaining weight and balance control of the aircraft.
The handbook shall take the _______ security classification of the data contained therein.
DD FORM 365.
Record of Weight and Balance Personnel is used to provide a continuous record of weight and balance personnel responsible for maintaining the aircraft weight and balance handbook and preparation of DD Form 365-4
DD FORM 365-1
CHART A- BASIC WEIGHT CHECKLIST RECORD is completed collection of DD Forms 365-1 for particular aircraft. A list of basic weight equipment and other items, by aircraft compartment, which are/may be, installed in the aircraft.
DD FORM 365-2; FORM B- AIRCRAFT WEIGHING RECORD
Used to record data obtained from the aircraft weight and balance measurement.
DD FORM 365-3; CHART C- BASIC WEIGHT AND BALANCE RECORD
Continuous series of completed DD Forms 365-3. It's a continuous and permanent record of aircraft weight, moment or index, and center of gravity position.
CHART E- LOADING DATA
Contains loading data, charts, graphs and other info necessary to perform acft loading control (W&B flight clearance computations) and to accomplish actual weighings to ensure the acft remains within its weight and balance limitations.
DD FORM 365-4; FORM F- WEIGHT AND BALANCE CLEARANCE FORM
Records the weight, moment or index, and center of gravity calculations for a specific acft to ensure the acft remains within its w&b limitations.
CALCULATION AIRCRAFT CENTER OF GRAVITY (C.G.)
The c.g. of loaded acft can be calculated when the weights & arms of the items which make up the acft gross weight are known. This can be done by using moments. The relationship between weight, arm and moment is:
WEIGHT x ARM = MOMENT.
sometimes design, manufacturing and maint. changes cause the acft c.g. to exceed it's limits. This is usually corrected by addition of permanent ballast that always remains in the acft. When the ballast is added to counter the temporary removal of an item or to balance a particular configuration, it's called temporary ballast.
NAVAL AIR SYSTEMS COMMAND RESPONSIBILITIES
NAVAIRSYSCOM shall maintain overall responsibility for establishing the requirements, procedures, and forms format for USN/USMC acft W&B control.
Naval Air Systems Command
The acft manufacturer inserts all identifying data on the title page of the W&B Handbook and completes all other applicable charts prior to delivery of the acft
Shall ensure that reporting custodians establish an effect system for weight and balance control of acft assigned to their command
REPORTING CUSTODIAN RESPONSIBLITIES
- -R.C. shall establish effective operating procedures for W&B control of assigned acft to their command.
- -Shall designate a qualified W&B Officer, and any additional qualified W&B personnel IAW OPNAVINST 4790.2
- -Shall ensure that W&B control system requirements and procedures of this manual, and related technical documentation, are complied with IAW mgmt procedures of OPNAVINST 4790.2 and OPNAVINST 3710.7. THe W&B control system requirements and procedures shall include but not necessarily be limited to ensuring:
- *W&B handbooks for all assigned acft, including newly received acft, are complete, current and maintained in the correct format.
- *afct are configured with proper amounts of ballast required to maintain the acft within the prescribed c.g. limits throughout its flight. The addition of ballast must not impair the structural integrity of the acft and therefore any new ballast must be approved by NAVAIRSYSCOM before it can be installed. Whenever ballast is required to balance an acft after the removal of equipment, ballast may be placed in the vacant equip mounts up to the weight of the removed equip.
PERSONNEL QUALIFICATION REQUIREMENTS
Personnel assigned the responsibility for accomplishing the various administrative and record keeping functions for W&B control of assigned acft must qualify by graduation from one of the FASO W&B classes.
Personnel assigned responsibility for weighing acft must be qualified by graduation from one of the FASO weight and balance classes, successful completion of the Society of Allied Weights Engineers acft weighing course or NAVAIRSYSCOM accepted equivalent, plus have actual experience with active participation in minimum of 20 acft weighings covering at least 4 different TMS acft, of 6 weighings of specific TMS acft when the individual will be weighing only this TMS acft. Weighing experience must have been obtained within the previous year.
Personnel designated as Lead W&B Specialist at the NADEPS must be qualed by graduation from one of the FASO W&B classes, successful completion and the Society of Allied Weights Engineers acft weighing course or NAVAIRSYSCOM accepted equivalent, plus have 12 months of continuous actual experience in weighing acft with active participation in minimum of every 60 acft, including at least 5 different TMS acft. Weighing experiences must have been obtained within previous 2 years.
CLASS 1 ACFT
Are those whose recommended weight and c.g. limits sometimes can be exceeded by loading arrangements normally employed in operations and therefore need loading control.
CLASS 2 ACFT
Are those whose recommended weight and c.g. limits can more readily be exceeded by loading arrangements normally employed in operations and, therefore need a lighter degree of loading control
