BS ISO 20683-2:2016适用于与机头连接的无牵引杆飞机牵引车（TLTV） 最大坡道质量在10000到10000之间的民用运输飞机起落架 50000公斤（220000和110000磅），通常被称为“支线飞机”对 ISO 683规定的最大质量运输干线为更高的飞机。事实并非如此 适用于出版日期前制造的TLTV。它规定了一般设计要求、测试和评估要求、维护、校准、， 文件、记录、追踪和问责要求，以确保 牵引车辆产生的牵引力不得超过前起落架或其转向系统的设计载荷，或 降低前起落架经认证的安全寿命极限，或在飞机推进过程中引发稳定性问题 倒车和/或维修牵引操作。本文件规定了无拖车杆牵引车（TLTV）的要求和程序 仅适用于飞机后推和登机门重新定位或维修牵引。这并不是为了允许 调度（运行）牵引（见第3条）。调度拖航会对前起落架和前起落架施加更大的载荷 由于速度和额外的乘客、货物和燃料负载的组合，飞机结构。本文件不适用于与飞机主起落架连接的无牵引杆牵引车。交叉引用:ISO 6966-1ISO 6966-214 CFR第25部分ISO 9000ISO 9001SAE ARP591SAE ARP59116SAE ARP5285购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS 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.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.Cross References:ISO 6966-1ISO 6966-214 CFR Part 25ISO 9000ISO 9001SAE ARP5911SAE ARP5916SAE ARP5285All current amendments available at time of purchase are included with the purchase of this document.
