The moment change for the outboard tanks x is 84, in.

Aircraft Mass & balance (JAA ATPL theory).

Perrone Leather Phillips 66 Avi. The manual load and trim sheet shown at Figure looks complex but is in fact straightforward. The fuel required to proceed from the destination to the alternate aerodrome in the prevailing conditions.

This is known as role equipment, an example would be the passenger seats, toilets and galleys, which may vary in quantity for a large public transport aircraft. If the aircraft has not been re-weighed, the revised Weight and Centre-of-Gravity Schedule shall contain a statement that calculations have been based on the last Weight and Balance Report, or other information, and the known weight and CG changes.

Some aircraft have more than one CG envelope.

Incorrect loading of the aircraft could have immediate and devastating consequences. 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 weights measured through each wheel are: The centre of gravity is that point on the longitudinal axis through which all of the weight acts vertically downward. Now add all of the moments together to get, in this case,inch-pounds.

Similarly, when converting imperial gallons to pounds the volume must be multiplied by 10 x the specific gravityor to convert pounds to imperial gallons the volume must be divided by 10 x the specific gravity of the liquid. Columns shall also be provided for recording an example of a typical aircraft loading calculation. The date and reference number of the Weight and Balance Report, or, as appropriate to the weight, other acceptable information upon which the Schedule is based, shall be given.

The moment of this force is equal to the product of the weight and the distance at which it is placed from the fulcrum. Recording of Mass Values.

All the data regarding the medium range jet transport aeroplane are contained in the white pages of the CAP Henkel Loctite Henkel Structur. The weight of the aircraft shown in the weight schedule the basic weight plus such additional items in or on the aircraft as the operator thinks fit to include. The following examples illustrate the method of calculating the weight and arm of empty aircraft with various datum positions.

How much freight must be added to a hold 10ft forward of Datum to move the CG 1ft forward. 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. Reserve Fuel remains unused 7, kg. Aft cabin baggage area lb. Insert at 18 and Basic equipment is that which is common to all roles plus unconsumable fluids such as hydraulic fluid. The layout of the seats, baggage stowage areas and fuel tanks is shown at Figure and Figure Figure shows only three of the infinite combinations possible.

Calculate the maximum traffic load.

The position of the centre of pressure depends on the angle of attack, with agpl C of P moving slowly forward as the angle increases, and then rapidly backwards at the stalling angle.

If one now jass mass and weight as being synonymous, then 1 kilogram is equal to 9. Imperial Units are shown on the specimen. Fleet Mass and CG Position a Chapter 10 Page 2 For a fleet or group of aeroplanes of the same balancce and configuration, an average dry operating mass and CG position may be used as the fleet mass and CG position, provided that the dry operating masses and CG positions of the individual aeroplanes meet the tolerances specified below.

Therefore weight and mass are synonymous. The revised baggage distribution is therefore as shown in the table which follows.

That part of the oil lubrication system that cannot be removed due to the construction of the system. How much freight must be added to hold arm 5 ft. Basic aircraft Arm It may be impossible to distribute the traffic load such that the centre of gravity of the laden aircraft remains within the safe specified limits, in which case some of the traffic load may have to be off-loaded. The landing weight is the take-off weight less the total weight of fuel used in flight.

Fuel at take-off lbs in tank 10ft forward of Datum. Chapter balanfe Page 8 Forwards 3g Rearwards 1. Chapter 9 Page 12 d Operators have the option to submit a detailed survey plan to the Authority for approval and subsequently a deviation form the revised standard mass value providing this deviating value is determined by use of the procedure explained in the Appendix. Orcon Corp Organic Product. Determine the maximum payload that could be loaded at A and B.

If any last minute change occurs after the completion of the mass and balance documentation, this must be brought to the attention of the Commander and the last minute change must be entered on the mass and balance documentation. Every effort has been made to ensure the validity and accuracy of the material contained herein, however no responsibility is accepted for errors or discrepancies.

All public transport aircraft are divided into Classes in which the types have similar levels or performance. C of G 2 ft aft of datum. The revised standard mass values can only be used in circumstances consistent with those under which the survey was conducted. The restraint factor for fixed wing aircraft is expressed in multiples of the force of gravity.
