BS ISO 8267-1:2015规定了机头上牵引杆连接配件的接口要求 传统三轮车式起落架中的起落架（当从前起落架执行牵引操作时） 商用民用运输客运和货运飞机的齿轮。其目的是通过飞机质量实现牵引杆连接配件接口标准化 类别（决定牵引杆力），以确保单一类型的牵引杆 标准连接可用于该质量类别内或附近的所有飞机类型，以帮助 运营商和机场地勤公司减少了不同类型拖车杆的使用。ISO 8267的本部分适用于规定最大值范围内的所有新型干线飞机 坡道质量范围，在发布日期后投入使用或设计。ISO 8267的本部分适用于经适航认证的干线商用运输机 根据FAR/EASA-CS第25部分，最大坡道质量>50000 kg（110 000 lb）。它不适用于根据FAR/EASA-CS第25部分认证的适航飞机，但具有 最大坡道质量≤ ISO 8267-2涵盖了50000千克（110 000磅）。如果一系列现有或计划中的飞机类型连接两个质量类别，则使用单一牵引 杆连接配件接口，为所有这些，并考虑使用标准尺寸的 整个家庭都有更高的群体类别。注:就实际情况而言，ISO 8267的这一部分的定义是为了与尽可能多的现有标准兼容 相关质量类别中尽可能多的飞机类型。交叉引用:EASA CS-25ISO 8267-2购买时可用的所有当前修订版均包含在本文件的购买中。

BS ISO 8267-1:2015 specifies the interface requirements for tow bar attachment fittings on the nose gear (when towing operations are performed from the nose gear) in conventional tricycle type landing gears of commercial civil transport passenger and freight 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 part of ISO 8267 is applicable to all new models of main line aircraft within the specified maximum ramp mass range, entering service or designed after its date of publication.This part of ISO 8267 is applicable to main line commercial transport aircraft of 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 of 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 8267-2.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 throughout the family.NOTE As far as practical, this part of ISO 8267 was defined in order to be compatible with as many existing aircraft types as possible in the mass category concerned.Cross References:EASA CS-25ISO 8267-2All current amendments available at time of purchase are included with the purchase of this document.
