标准摘要
[中文适用范围]： 本文件适用于与干线民用运输飞机的前轮起落架接口的无杆牵引车（TLTVs），最大停机坪质量超过50000公斤（110000磅）。区域运输飞机的最大停机坪质量较低的要求在ISO 20683-2中规定。对于本文件发布之前制造的无杆牵引车不适用。本文件规定了一般设计要求、测试和评估要求、维护、校准、文档记录和可追溯性要求，以确保牵引车施加的载荷不超过前起落架或其转向系统的设计算载荷，或降低前起落架认证的安全寿命限制，或在飞机推出和/或停机位重新定位或维护牵引操作中引发稳定性问题。本文件规定了适用于飞机推出和停机位重新定位或维护牵引的无杆牵引车（TLTVs）的要求和程序。它不旨在允许用于放行（操作）牵引（见第3章）。放行牵引对前起落架和飞机结构施加更大的载荷，因为速度与乘客、货物和燃料载荷的结合。本文件不适用于与飞机主起落架接口的无杆牵引车。 [外文原描述]： ISO 20683-1:2016 is applicable to towbarless aircraft towing vehicles (TLTVs) interfacing with the nose landing gear of main line civil transport aircraft with a maximum ramp mass over 50 000 kg (110 000 lb). The requirements for regional transport aircraft with a lower maximum ramp mass are specified in ISO 20683‑2. 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 pushback and/or gate relocation or maintenance towing operations. This document 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. This document does not apply to towbarless towing vehicles interfacing with aircraft main landing gear.
