Verification of Cargo Weights


This Commercial & Business Aviation Advisory Circular (CBAAC) is intended to remind air operators of the requirement to use the actual cargo weights in Weight and Balance Control.


This CBAAC applies to all air operators operating under Subparts 701, 703, 704, and 705 of the Canadian Aviation Regulations (CARs).


  • Sections 602.07, 703.37, 704.32 and 705.39 of the CARs.
  • Sections 723.37, 724.32 and 725.39 of the Commercial Air Services Standard (CASS).
  • Guidance Material, Subparts 703, 704 and 705 of the CARs.


On October 20, 2004, the Transportation Safety Board of Canada issued Aviation Safety Advisory A04H0058-1 entitled - Cargo Handling - Verification of Cargo Weights.


The referenced CARs and CASS are specific. In reference to weight and balance control the regulations and standards refer to " ...the actual weight of cargo... "

The intent of the CARs is to ensure that the actual weight of the cargo, including the weight of the contents, the packing material, the packaging, the pallet or unit load device (ULD), the strapping, the wrapping and any other device or material being transported with the cargo is accounted for in the total weight of the cargo. This weight may be obtained by either weighing each built pallet or ULD at the point of loading, or by adding the actual weight of all the components of each pallet or ULD.

It is not acceptable to use the advertised weight of the product inside a box as the actual weight of the box. The weight of the packaging and the box itself must be considered in addition to the weight of the product inside.


Air operators are requested to verify that the actual weights of cargo are used as intended in the standard, in their approved weight and balance system.

The actual weight of cargo being the weight of the contents, the packing, packaging, straps, box, pallet, and / or container.


This CBAAC will remain in effect until further notice.
