The methodology for maximum package size loading is based on a mathematical method allowing the calculation of maximum package size tables.

This method does not in principal differentiate between bulk loading and cargo system loading.

However, some restrictions have to be considered:

• Some cargo systems generate pre-determined pallet trajectories. Envelope curves depending on the pallet size and the possible trajectories have to be determined first.

• Door geometric limitations (with or without cargo loading system)

• Turning limitations due to weight, load geometry and conveyance capability

• Securing requirements

This document is not intended for airline operational use. It should be used by engineers performing calculations or developing computer programs to produce Maximum Package Size tables specified in AS1825.

Purpose:

The purpose of this document is to provide mathematical support to establish and verify max. package loadability and max. package size tables for given cargo hold dimensions.

This standardized methodology shall be:

• applicable for any given aircraft and each compartment

• based on a defined and practicable loading procedure

• exact for the range of maximum size packages within a rectangular contour envelope

• referenced as basic methodology, to identify geometrical variants
