The purpose of this specification is to provide airplane operators and tow vehicle manufacturers with:
General design and operating requirements pertinent to test and evaluation of towbarless tow vehicles. Specific design requirements are provided in ARP4852A and ARP4853A.
Test and evaluation requirements. The results of these test evaluations will determine if the loads induced by the tow vehicle will exceed the design loads of the nose gear, reduce the certified safe life limit of the nose gear, or induce a stability problem during pushback and/or maintenance towing operations.
This document specifies general test requirements and a test evaluation procedure for towbarless tow vehicles (TLTV) intended for pushback and maintenance towing only. It is not meant for dispatch (operational) towing (see definitions in Section 3). Dispatch towing imposes greater loads on nose gears and structure due to additional passenger, cargo, and fuel loads. Airframe manufacturers may require submittal of test results for evaluation or may provide information which allows TLTV manufacturers or airlines to self-test or evaluate the towbarless tow vehicles themselves. Refer to the airframe manufacturer's documentation for evaluation requirements and detailed testing procedures that may be different than contained in this specification.
TLTV manufacturers may elect to prepare and provide customers or regulatory agencies with a “Certificate of Compliance” or equivalent documentation as evidence that successful testing and evaluation of a specific tow vehicle/airplane type combination has been completed in accordance with this ARP and/or the applicable detailed airframe manufacturer’s documentation. This certification will allow usage of the vehicle on specifically designated airplane model types. The certificate should be established under an appropriate quality control program meeting the requirements of ISO 9000 Series or equivalent.
This specification requires that the TLTVs under consideration be maintained and operated in a serviceable condition. In addition, the vehicle to airplane interface protection system shall be calibrated periodically. This information is defined in ARP5284 and ARP5285.
This document was prepared with the assistance of Airbus, Boeing, and McDonnell Douglas.

AGE-3 Aircraft Ground Support Equipment Committee
AGE-3 is the Aircraft Ground Support Equipment Committee that addresses all aspects of airport, ground support equipment and associated systems that interface or require compatibility with the aircraft. The objectives of the Committee are:
- Develop and maintain technical standards, specifications and reports related to aircraft ground servicing and in particular to:
- Airport Ground Support Equipment (GSE)
- Aircraft to GSE interface
- GSE operation, maintenance and operator training
- Airport facilities and systems that have a direct relationship to and interface with GSE
- GSE environment related issues, including noise and emissions.
- Provide a forum for exchange of technical information related to aircraft ground operations where issues can be addressed and resolved.
- Coordinate and harmonize worldwide standards development with CEN TC 274, ISO TC 20/SC9, IATA GSEE and other standardization groups.
- Promote the global use of high quality standards and practices within the aircraft ground servicing scope.
- Promote research and innovation in any topics related to the scope of the Committee.
Participants in the SAE AGE-3 include OEMs, ground handling companies, airlines, suppliers, consulting firms and other actors across the aerospace and defence industries.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
