The fuel in the same tank on Landing lbs calculate the change of moments. Children Infants are persons who have not yet reached their second birthday.
Jeppesen. JAA ATPL Training Mass and Balance
The maximum payload that can be loaded at B is 6, kg. In the case considered above and illustrated at Maathe CG of the seesaw is immediately above the fulcrum. The role equipment variable load detailed in Part B may be for as many roles as the operator wishes, but for every role the weights and moments must be stated.
The current restraint load factors are: Maximum Zero Fuel Weight 31, kg. Page Paragraph 17 d. In the event that the position of the undercarriage extended or retracted will significantly affect the position of the basic aircraft CG, the loading information contained in Part C of the Weight and CG Schedule will contain a statement of the total moment change which occurs when the undercarriage is lowered. As you can see from the following diagram the method of use is precisely the same as the previous example.
Weight and Traffic Load 1. All of the weights used in the above examples are assumed to be of uniform density and construction such that the weight acts vertically downward through the centre of the weight.
The diagram at Figure may help you with these conversions. The CG is the point on the longitudinal axis through which all of the weight acts vertically downward. What determines the maximum zero fuel weight? Role equipment is that which is required to complete a specific task such as seats, toilets, galley for the passenger role or roller conveyor, lashing points and tie down equipment for the freight roles.
Sector Distance 1, nm. In other words anything or anyone carried that earns money for the airline. The distance between the maximum safe forward position of the CG and the maximum safe aft position of the CG is termed the CG envelope.
The Maximum Take-off Weight. No differentiation according to sex shall be made for children, atpll are defined as persons of an age of two years but who have not yet reached their twelfth birthday.
Where there are any other significant quantities of consumable fluids or substances e. The traffic load plus usable fuel is also referred to as the disposable load.
Rear baggage hold lb. All details of the fuel are on Page 22, passenger distribution on Page 23 together with standard mass values for the crew and passengers. Additional fixed weights atll can be removed, if necessary, that are carried, to ensure the centre of gravity remains within safe limits, in certain circumstances. In addition to ensuring that the maximum permissible all-up weight of an aircraft arpl not exceeded it is of vital importance to ensure that the distribution of the permissible weight is such that the balance of the aircraft is not upset.
Calculate the dry operating weight. The weights measured through each wheel are: For an masz to perform a particular role it may be necessary to fit additional equipment. The fuel required to be used from overhead the landing aerodrome to the end of the landing roll.

Therefore any product combination of weight and arm which gives a moment of 16 m kg will suffice. Maximum Take-Off Weight at Akg.
Conversely, when moving in the opposite direction, divide. The position of the CG measured along the fore and aft axis of the aircraft will change due to changes in aircraft configuration passenger configuration with seats in, freight configuration with seats outtotal weight and distribution of the fuel load at any given point in the flight, total weight and distribution of the payload, and so on.
Insert at 18 and The turning moment at any particular point can be determined by multiplying the weight the downward force by the arm the distance of that point from the fulcrum. The gross weight of the aeroplane, including all of its contents, at the time of landing. Fuel at take-off 10,kgs; Trip fuel 5,kgs. By convention any weight which is positioned forward of the reference datum has a negative arm and therefore produces a negative moment.
The texts balxnce subject to frequent changes which are beyond our control. The maximum total weight of aircraft prepared for service, the crew unless already included in the APS weightpassengers, baggage and cargo at which the aircraft may take-off anywhere in the world, in the most favourable circumstances in accordance with the Certificate of Airworthiness in force in respect of aircraft.
Reserve Fuel 6, kg. The amended table should now appear as at Figure Not part of the specimen Schedule. Standard weights are assumed for this exercise. The total weight of the aeroplane comprises the APS weight plus the disposable load, which is made up of usable fuel and the payload. This is basically the out of breath family that has made it from check-in to the gate in record time and arrived just as you are baalnce to push back.
It is possible, although presently unlikely, that you may encounter aircraft weights expressed in Newtons.
