标准摘要
[中文适用范围]： 本文件适用于无杆牵引车（TLTVs），这些车辆与客机前轮起落架接口相连，该类飞机的最大滑行质量介于10,000 kg至50,000 kg（22,000 lb至110,000 lb）之间。 本文件不适用于在其发布日期之前制造的无杆牵引车。 它规定了通用设计要求、测试和评估要求、维护、校准、文档记录和可追溯性要求，以确保牵引车辆施加的载荷不超过起落架或其转向系统的 设计载荷，或不影响前起落架的认证安全寿命极限，或在飞机推出和/或维护拖行操作期间产生稳定性问题。 [外文原描述]： ISO 20683-2:2016 is applicable to towbarless aircraft towing vehicles (TLTVs) interfacing with the nose landing gear of civil transport aircraft with a maximum ramp mass comprised between 10 000 and 50 000 kg (22 000 and 110 000 lb), commonly designated as "regional aircraft." The requirements for main line transport aircraft with a higher maximum ramp mass are specified in ISO 20683‑1. It is not applicable to TLTVs which were manufactured before its date of publication. It specifies general design requirements, testing and evaluation requirements, maintenance, calibration, documentation, records, tracing and accountability requirements in order to ensure that the loads induced by the tow vehicle will not exceed the design loads of the nose gear or its steering system, or reduce the certified safe life limit of the nose gear, or induce a stability problem during aircraft push back and/or maintenance towing operations. It specifies requirements and procedures for towbarless tow vehicles (TLTVs) intended for aircraft pushback and gate relocation or maintenance towing only. It is not intended to allow for dispatch (operational) towing (see Clause 3). Dispatch towing imposes greater loads on nose gears and aircraft structure due to the combination of speed and additional passenger, cargo, and fuel loads. It does not apply to towbarless towing vehicles interfacing with aircraft main landing gear.
