Cargo Compartments Maximum Package Size Calculation Methodology

HISTORICAL
AIR4899
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.

Environmental Degradation of Composite Materials

CURRENT
ARP6287
In accordance with § 4.11 of AS36100, materials used in the construction of pallets, nets, and containers shall take into account the effects of environmental conditions, such as temperature, humidity, and UV degradation, expected in service. In accordance with (E)TSO-C90, the applicant shall consider environmental degradation due to aging, ultra-violet (UV) exposure, weathering, etc., for any materials used in the construction of pallets, nets, and containers. The purpose of this Aerospace Recommended Practice (ARP) is to provide guidelines for the basic requirements to be considered regarding environmental degradation effects when qualifying composite materials in the design to fulfill the (E)TSO-C90 Minimum Performance Standard. Material qualification is the verifying of a materials attributes and characterizations, which are typically determined through testing.

AIR4165A
This SAE Aerospace Information Report (AIR) is intended to assist the user (aircraft manufacturer/airline) in the following areas: a In the decision of whether or not to plan for the installation of a powered drive system in the cargo loading system (CLS) during the definition of the aircraft on-board cargo loading system. b If a powered drive system is decided upon, to provide general requirements to be considered during the preparation of component specifications for the powered drive units (PDUs) to be used. This provides a selection of criteria in order to obtain an optimum PDU for the application considered.

The tests are static in nature to minimize complexity and cost of required testing facilities. As far as practical, applied static loads should take into account the combined static and dynamic loads anticipated in service. It is intended that tests shall be non-destructive in nature and not result in damage unless ultimate load conditions are employed. Test equipment and methods of testing described are not meant to be restrictive. Alternate equivalent methods to accomplish the desired results may be employed. In selected cases, tests may be repeated under ultimate load conditions when required for substantiation of analytical data. If this becomes necessary, the parts deformed may be removed and replaced prior to the retest.
