Air cargo unit load devices — Performance requirements and test parameters

This document specifies the minimum requirements for airworthiness approval of air cargo pallets, nets and containers, generally designated as air cargo unit load devices (ULD). This document is intended to provide a uniform technical reference for air cargo unit load devices approval. As a prerequisite, it is presupposed that the applicable general civil aviation requirements and the aircraft manufacturer's approved Weight and Balance Manual are followed. This document defines the minimum performance requirements and test parameters for air cargo unit load devices requiring approval of airworthiness for installation in an approved aircraft cargo compartment and restraint system that complies with the cargo restraint and occupant protection requirements of EASA CS-25 or 14 CFR Part 25, except for the 9,0 g forward ultimate inertia force of § 25.561(b) (3) (ii). This document applies to airworthiness approved air cargo unit load devices intended for carriage on board civil transport category airplanes type certificated under EASA CS-25 or 14 CFR Part 25, or equivalent. This document exclusively applies to unit load devices airworthiness approval and testing parameters. It does not apply to aircraft design or aircraft operating requirements, which are provided by the approved Weight and Balance Manual for each aircraft type. Other aspects that do not directly pertain to air cargo unit load devices airworthiness approval and testing are not covered by this document and are defined in other International Standards (see Bibliography), e.g.: — ULD design specifications, — ULD in service damage limits, — ULD restraint malfunction limitations, — ULD test methods, — ULD load distribution models, — ULD maximum allowable contours, — ULD CG (centre for gravity) location control means, — ULD pressure equalization methods, — ULD utilization guidelines. Air cargo unit load devices qualified prior to publication of this document were approved in accordance with the requirements of ISO 8097:2001. This document is intended as a TSO approval reference for all new models of unit load devices in the sizes and types it covers, in replacement of ISO 8097. For air cargo unit load devices the size or type of which is not covered in this document, see the requirements of ISO 8097:2001, if their size or type is contained therein, or other equivalent criteria, if not. NOTE 1 ISO 8097 is based on USA National Aerospace Standard NAS 3610 revision 10:1990, Specification for Cargo Unit Load Devices. NOTE 2 The requirements for cargo covers are not defined in this document, except insofar as net restraint is incorporated therein.

Air cargo unit load devices — Load distribution model

This document defines the industry agreed model for load distribution on air cargo unit load devices (ULD) bases to apply the maximum allowable centre of gravity (C.G.) eccentricity. Its purpose is to establish a common reference load distribution algorithm for: a) comparable and repeatable ULD testing methods, or equivalent numeric simulations; b) aircraft structure and cargo systems design assumptions, consistent with existing airframers practices; and c) definition of operators unit load devices utilization rules and cargo build-up training programs. It applies to all types of unit load devices intended for use on board civil transport aircraft and airworthiness approved in accordance with the performance requirements and testing parameters of either ISO 21100 or, as applicable, ISO 8097. It also applies to non-airworthiness approved (non-certified) containers as defined in ISO 4118, the utilisation of which is controlled by the provisions of the aircraft type's Weight and Balance Manual and other airframe manufacturer's documents.

Aircraft — Deicing/anti-icing methods on the ground

This document establishes the minimum requirements for deicing/anti-icing methods on the ground of main line and regional airplanes, in accordance with ICAO, Document 9640-AN/9401) and the relevant civil aviation requirements, to facilitate the safe operation of main line and regional civil transport airplanes during icing conditions. This document does not specify requirements for specific aircraft model types. Airlines' published manuals, procedures or methods supplement the information contained in this document. Frost, ice or snow deposits, which can seriously affect the aerodynamic performance and/or controllability of an aircraft, are effectively removed by the application of the procedures specified in this document. It is the airplane operator's responsibility to consult airplane manufacturer's aircraft operations manual, aircraft maintenance manual and service letters to determine any limitations/restrictions relating to the use of deicing/anti-icing methods meeting this document for the type and model of airplane to be treated.

Aircraft — Tow bar attachment fittings interface requirements — Part 2: Regional aircraft

This document specifies the interface requirements for tow bar attachment fittings on the nose gear (when towing operations are performed from the nose gear) of conventional tricycle type landing gears of commercial civil transport aircraft. Its purpose is to achieve tow bar attachment fittings interface standardization by aircraft mass category (which determines tow bar forces) in order to ensure that a single type of tow bar with a standard connection can be used for all aircraft types within or near that mass category, so as to assist operators and airport handling companies in reducing the number of different tow bar types used. This document is applicable to all new models of regional aircraft within the specified maximum ramp mass range which enter service or are designed after its date of publication. It does not apply to previously in service regional aircraft models, which present a considerable variety of tow bar attachment fittings. However, a simple retrofit modification is described that may make certain in-service fittings compatible with a tow bar head in conformity with this document, where deemed appropriate in order to facilitate operation of such aircraft types at airports. This document is applicable to regional commercial transport aircraft airworthiness certified under FAR/EASA-CS Parts 25 with a maximum ramp mass of ≤ 50 000 kg (110,000 lb). It does not apply to — aircraft airworthiness certified under FAR/EASA-CS Parts 23 as commuter category aeroplanes, and — aircraft airworthiness certified under FAR/EASA-CS Parts 25 but with a maximum ramp mass of > 50 000 kg (110,000 lb), which are covered by ISO 8267‑1. Where a family of existing or contemplated aircraft types bridges two mass categories, use a single tow bar attachment fitting interface for all of them, and consider the use of the standard dimensions for the higher mass category, be it part of this document or ISO 8267‑1, throughout the family. NOTE As far as practical, this document was defined in order to be compatible with as many existing aircraft types as possible in the mass category concerned.

Aircraft — Ground service connections — Locations and types

ISO 10842:2017 specifies the locations and types of aircraft ground service connections in order to optimize ground services both fixed and mobile, for the seven different services hereafter: - 400 Hz electrical power; - preconditioned air for cabin conditioning; - pneumatic power for jet engine start; - potable water; - lavatory service (draining, flushing); - aircraft refuelling; - interphone (headset) connections. It focuses on these aircraft services because: - these connections are those most frequently used during aircraft airport turnaround operations; - in terms of economic benefit, they have the greatest impact through improved efficiency. ISO 10842:2017 is intended to apply to any new type of main line commercial transport category aircraft designed or built after its publication. In addition, it is expected that any substantially modified new derivative aircraft type in the same category (derived from a previously existing type) will, insofar as technically and economically practical, meet the requirements of this document, if specified in the aircraft type specification established between customer airline(s) and manufacturer. It is not the intent of this document to restrict in any way the basic design of any future types of civil passenger transport aircraft. It aims, however, at clarifying for aircraft design engineers the design characteristics which would make it difficult or impossible for a new type of aircraft to be adequately serviced from existing airport facilities. Should basic aircraft design requirements impose on a future model certain characteristics not complying with the present document: - either alternative methods of servicing the aircraft will have to be implemented; or - existing facilities in the airports where such a new type of aircraft is to operate will require some degree of modification/rework; or - additional interface devices/equipment will be required in order to service such a new type of aircraft; in either case resulting in increased aircraft servicing constraints and operating cost.
