When loading cargo onto an aircraft, it is important to ensure that the cargo is properly secured and stabilized to prevent damage during transit. One common method of securing cargo is to use pallets and pallet nets to create stacks of cargo, which are then lashed down using lashing straps or other tie-down equipment.

To build a pallet stack, cargo handlers first lay out a pallet net on the base of the stack, and then begin loading cargo onto the net. As each layer of cargo is added, another pallet net is placed on top, with the cargo placed on top of the net. This process is repeated until the desired height of the stack is reached.

Once the stack is complete, cargo handlers must then secure the stack using lashing straps or other tie-down equipment. The number of lashing straps required will depend on the size and weight of the stack, as well as the loading position on the aircraft. It is important to use enough lashing straps to ensure that the stack is securely tied down and will not move during transit.

In some cases, additional cargo may be loaded on top of a pallet stack, provided that the maximum gross weight of the aircraft is not exceeded. However, it is important to carefully monitor the weight of the cargo and the stack to ensure that it is within the allowable limits for the specific loading position on the aircraft.

Note: Pallet stacks should not exceed 24 pallets on passenger aircraft
