The following examples illustrate the method of calculating the weight and arm of empty aircraft with various datum positions. Aeroplanes that have been modified but the effects on the weight and balance are unknown must be re-weighed. Klixon Knots 2U Korry Electroni. This Appendix contains acceptable means of compliance in respect bslance Weight and Centre-of-Gravity ,ass Loading and Distribution Schedules provided in accordance with the requirements. Infants shall be weighed together with their accompanying adult.

The effectiveness of a load spreader is established by its thickness, not its overall size. C of G arm 3 ft aft of datum. The magnitude of the pitching moment will depend on the magnitude of lift and weight forces, but also on the distance between the centre of gravity and the centre of pressure.

Additional fixed weights which can be removed, if necessary, that are carried, to ensure the centre of gravity remains within the safe limits, in certain circumstances. The weight of fuel contained in particular tanks must be included in the zero fuel mass when it is explicitly mentioned in the Aeroplane Flight Manual limitations.

If it isn’t you must find your error before proceeding. This is a structural limitation imposed to ensure that the airframe is not overstressed.

This should include the lever arms of fuel, oil and other consumable fluids or substances in the various tanks including agricultural material in hoppers which, if necessary, should be shown diagrammatically or graphically; lever arms of passengers in seats appropriate to the various seating layouts; mean lever arms of the various baggage holds or compartments.

Enter the weight of the item in the weight column. This is the basic weight plus role equipment.

031 Aircraft Mass & balance (JAA ATPL theory)

Maximum Landing Mass 54, kgs. Where there are any other significant quantities of consumable fluids or substances e.

Determine the traffic load which can be mas from A to B. Fuel is delivered in litres, imperial gallons or US gallons, but of course must figure in the load sheet calculations in pounds or kilograms. This is the fuel used from departure to destination aerodromes and may be minimised by operating at the most economical pressure altitude accounting for the temperature and wind component, but not below the minimum safe balanve.

Material, usually thick wood, utilised to protect the aircraft floor, including ramps, jass provide a continuous pathway over which wheeled vehicles may transit when being positioned in the fuselage prior to lashing down without exceeding the maximum area limit at any point.

Now complete the pro forma and plot the results for the following examples. Maximum Take-Off Weight at B 37, kg. Therefore weight and mass are synonymous.

The position of the centre of pressure depends on the angle of attack, with the C of P moving slowly forward as the angle increases, and then rapidly backwards at the stalling angle. Faithful adherence to the fuel management procedures as laid down in the AFM will ensure that the CG remains within the specified limits during the flight.

Rear baggage hold lb. Lab One Inc Lamar Technolog.

Imperial Units are shown on the specimen. The person preparing the mass and balance documentation must be named on the document. The maximum weight at which an aircraft may commence taxiing and its equal to the maximum take-off weight plus taxi fuel and run-up fuel.

The seesaw is said to be in equilibrium or to be balanced, and will therefore rest in a horizontal position. How much freight must be added to hold arm 5 ft.

Otherwise the weight of each person must be determined by weighing. Where it is necessary to use S. Fill in the pro forma and plot the results. In addition the Weight and Centre-of-Gravity Schedule for aircraft the Maximum Total Weight Authorised of which does not exceed kg, shall contain instructions for the determination of the halance weight, the total load moments and resultant CG positions.
