ISO 8267-1:2015规定了商用民用运输客货飞机常规三轮车式起落架中前起落架上牵引杆附件配件的接口要求（当从前起落架执行牵引操作时）。 其目的是通过飞机质量类别（决定牵引杆力）实现牵引杆连接配件接口标准化，以确保具有标准连接的单一类型牵引杆可用于该质量类别内或附近的所有飞机类型，从而协助运营商和机场处理公司减少使用的不同牵引杆类型的数量。 ISO 8267-1:2015适用于规定的最大坡道质量范围内、投入使用或在发布日期后设计的所有新型干线飞机。 ISO 8267-1:2015适用于根据FAR/EASA-CS第25部分认证的适航性主线商用运输机，最大坡道质量为>；5万公斤（11万磅）。 它不适用于根据FAR/EASA-CS第25部分认证的适航飞机，但其最大坡道质量为≤ 5万公斤（11万磅），这是ISO 8267-2所涵盖的。 在一个现有或设想的飞机类型的家庭桥梁两个质量类别，使用一个单一的拖曳杆附件拟合接口为他们所有，并考虑使用标准尺寸为更高质量类别在整个家庭。 注:就实际情况而言，ISO 8267本部分的定义是为了与相关质量类别中尽可能多的现有机型兼容。

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. ISO 8267-1:2015 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. ISO 8267-1:2015 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.
