This specification covers the requirements for solid-state frequency converters with 480 [or 380] V 3-phase, 60 [or 50] Hz input and 115/200 V, 3-phase, 400 Hz output capable of powering aircraft type loads requiring MIL-STD-704D quality power. The frequency converter shall be a self-contained unit suitable for the environment of intended use. Typical applications include dedicated use at passenger loading bridges (mounted under the bridge in telescoping bridge applications or fixed installation at base of stationary type loading bridges) with weatherproof enclosures or hangar/lab use where indoor fixed or portable units can be used.
This Aerospace Recommended Practice includes the following areas: basis for system requirements; selection of materials coupled with hazards and safety; configuration of design; system operation; and evalua tion testing.

This specification prescribes general requirements for marking of aircraft ground support equipment and other vehicles (i.e., runway sweepers, firetrucks, refulers, etc.), used on or near the flight line area with retro-reflective materials.
This SAE Aerospace Recommended Practice (ARP) applies to Point-Of-Use, Central and Mobile Pre-Conditioned Air Equipment. It does not apply to aircraft mounted equipment.
This SAE Aerospace Information Report (AIR) describes the characteristics and effects of using no-break power transfer (NBPT) methods when switching between auxiliary-power unit (APU) and ground-power unit (GPU). The GPU may be: a Point-of-use solid-state frequency converter, engine-generator, or motor-generator b Central system powered by motor-generator or solid-state frequency converter
This SAE Recommended Practice which defines the terms and tabulates the limits of the characteristics for various protective devices used in conjunction with 400-cycle ground power for civil aircraft is intended to assist the airlines in standardizing on 400-cycle protective systems. The limits found to be acceptable in the civil aircraft industry are presented.
The purpose of this specification is to provide airplane operators and tow vehicle manufacturers with: a General design and operating requirements pertinent to test and evaluation of towbarless tow vehicles. Specific design requirements are provided in ARP4852A and ARP4853A. b 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.
The purpose of this specification is to provide airplane operators and tow vehicle manufacturers with: a General design and operating requirements pertinent to test and evaluation of towbarless tow vehicles. Specific design requirements are provided in ARP4852 and ARP4853. b 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, or are within the aircraft manufacturer’s limits so that they do not affect the certified safe limit of the nose gear. The results of these test evaluations will also determine if a stability problem may occur during pushback and/or maintenance towing operations with the tested airplane/tow vehicle combination. This document specifies general test requirements and a test evaluation procedure for towbarless tow vehicles (TLTV) intended for pushback and maintenance towing only.
This SAE Aerospace Information Report (AIR) describes procedures for use in the field to determine if 115/200 Volt, 400 Hz aircraft external electrical power connectors are excessively worn, which may result in the inability of the external power plug to be retained, intermittent electrical performance and arcing.

The scope of this SAE Recommended Practice covers specialized internal combustion engine powered equipment used in support of aircraft operations. The equipment may be self-propelled, truck mounted, trailer mounted, skid mounted or stationary. It does not include construction equipment or equipment designed primarily for operation on highways or within factories or building areas. NOTE: Equivalent methodology is provided in (CEN) EN 1915-4, Aircraft ground support equipment - General requirements - Part 4: Noise measurement methods and reduction, to be used for measurements conforming to the EU Machinery Directive
