用途:航空货物托盘及其货物约束网构成飞机单元装载装置，由行业标准定义，并根据NAS 3610的要求，根据技术标准订单（TSO）C90c认证适航性。这保证了它们的设计对兼容机型的飞行具有本质安全性。然而，实际的飞行安全也要求正确使用这些经过认证的设备:大量事件表明，如果装载或限制不当，经过认证的ULD仍可能危及飞行安全。 因此，本ARP旨在提供公认的行业标准方法，以在准备空运货物托盘装载到飞机上时达到最佳安全水平，同时考虑到ULD适航认证要求、飞机制造商重量和平衡手册中表达的一般要求，以及根据经验确定的各种潜在关注领域。因此，本ARP提供了符合飞行安全目标的推荐实用方法，旨在作为承运人、托运人和货物装卸代理在建立自己的航空公司时的共同基础- 众议院出版物和员工培训计划。本ARP假设，任何准备好的空运货物托盘在放行装载到飞机上之前，都应由经过适当培训的合格人员进行检查，并发现其符合所有适用的飞行安全要求。在任何情况下，本ARP不得取代适用适航法规（见FAR第25部分）或飞机制造商的重量和平衡手册的要求。适用范围:本ARP旨在适用于由单个或多个商业货物组成的任何适航认证空运货物托盘，用于装载在民用运输飞机（无论是货机还是载客飞机）的下层、主甲板或上层。 其适用范围包括在地面场所内准备的所有托盘，无论是在托运人设施还是机场货物仓库，包括拟在“浮动”（即未完全受系统约束）位置装载到飞机上，需要系在飞机结构上而不是托盘轨道上的货物。其规定可能不完全适用于“预装载”托盘的情况，即:。，空托盘装载到飞机上，用作地板，货物随后在其上运送，并在货舱内装上托盘。 在这种情况下，操作员需要确定并实施适用的标准。本ARP不适用于为军用运输机准备的空运货盘，也不考虑军用飞机的任何具体标准。然而，任何情况都不排除将其用作指南。在这种情况下，它与军事运营商有关，以确定并实施任何其他适用标准。

Purpose:Air cargo pallets and their cargo restraint nets constitute aircraft Unit Load Devices, defined by industry standards and airworthiness certified based on Technical Standard Order (TSO) C90c in accordance with the requirements of NAS 3610. This guarantees their design to be intrinsically safe for flight on board compatible aircraft types. However, actual flight safety also requires these certified pieces of equipment to be properly used: numerous occurrences have demonstrated a certified ULD can nevertheless jeopardize flight safety if loaded or restrained in an inadequate manner.Accordingly, this ARP aims at providing recognized industry standard methods to achieve the best attainable level of safety when preparing air cargo pallets for loading on board aircraft, taking into account the requirements to be met as a result of the ULD's airworthiness certification requisites, the general requirements expressed in the aircraft manufacturers Weight and Balance Manuals, as well as the various potential areas of concern identified based on experience.This ARP therefore provides recommended practical means of compliance with flight safety objectives, intended to be available as a common base for carriers as well as shippers and cargo handling agents when establishing their own in-house publications and staff training programs.This ARP assumes any air cargo pallet prepared shall, prior to release for loading on board an aircraft, be inspected and found satisfactory by competent, suitably trained personnel responsible for checking it meets all applicable flight safety requirements.This ARP shall not, under any circumstance, supersede the requirements of applicable airworthiness regulations (see FAR Part 25) or the aircraft manufacturer's Weight and Balance Manual.Field of Application:This ARP is intended to apply to any airworthiness certified air cargo pallet built up from either a single or a number of pieces of commercial cargo, intended to be loaded on lower, main or upper deck of a civil transport aircraft, whether a freighter or a passenger carrying aircraft.Its field of application includes all pallets prepared within ground premises, whether at a shipper's facilities or an airport cargo warehouse, including those intended to be loaded into the aircraft in a "floating' (i.e., not fully system restrained) position requiring tie-down onto the aircraft's structure instead of the pallet's tracks.Its provisions may not entirely apply in the event of "pre- embarked' pallets, i.e., pallets loaded empty into the aircraft to be used as a floor on which cargo is later brought and palletized inside the cargo compartment. In such a case, it pertains to the operator to identify and implement the applicable criteria.This ARP is not intended to apply to air cargo pallets prepared for military transport aircraft, and does not take into account any specific criteria for military aircraft. Nothing, however, precludes it being used for guidelines in this case, it pertaining to the military operator to identify and implement any additional applicable criteria.
