The purpose of this SAE Aerospace Recommended Practice (ARP) is to standardize locations of aircraft ground service connections to accommodate the trend toward fixed systems, which use the passenger boarding bridge and/or underground “pop-up” or pit systems as a source of utilities. It must be recognized that, in standardizing the locations of the aircraft service connections, they must continue to be served efficiently in those instances where mobile ground support equipment is used. There is an ever increasing number of fixed installations for aircraft servicing. The objectives to be met by standardizing the locations of the aircraft service connections are the following:

This SAE Aerospace Information Report (AIR) is intended to cover all airport 50 or 60 Hz electrical systems as well as all electrical utilization equipment that is attached to those systems.

This SAE Aerospace Information Report (AIR) covers, and is restricted to, hands-on servicing/maintenance of industrial lead acid batteries used solely for motive power and exclusively for ground support equipment (GSE). It does not address or pertain to automotive-type SLI (starting-lighting-ignition) batteries or any other types of batteries (such as nickel-cadmium, zinc, or lithium batteries) which may be on-board airport GSE for either motive power or auxiliary uses. Similarly, the battery servicing and charging facilities described herein are those intended exclusively for industrial lead acid batteries.

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 following recommendations and suggestions are made for consideration for procurement of new equipment, or modification to existing equipment where practical. Excluded from this AIR is mobile ground equipment, such as fork lift trucks and front end loaders, that have a functional requirement for simultaneous vehicle motion and accessory operation.

This recommended practice outlines the general requirements of a continuous duty, electric motor-driven brushless alternator unit for supplying 400 Hz electrical power to high performance commercial transport aircraft. This specification is for a single motor-generator set with one or two outputs. The generator set will generate at the aircraft voltage of 115/200 volts. This unit may be used in a central system of small size or in hangar or electronic shop applications. Power characteristics of this unit at the receptacle will meet MIL-Standard-704 requirements. Other limits which are necessary to meet specific conditions must be specified by the purchaser.

This SAE Aerospace Recommended Practice (ARP) outlines recommended ramp pavement marking standards for proper guidance and positioning of GSE on commercial transport aircraft parking and handling stands (gates), in line with International Civil Aviation (ICAO) recommendations applicable to airport aprons. Throughout this document, the minimum essential criteria are identified by use of the key word “shall”. Recommended criteria are identified by use of the key word “should” and, while not mandatory, are considered to be of primary importance in providing safety effective ramp markings. Deviation from recommended criteria should only occur after careful consideration and thorough service evaluation have shown alternate methods to provide an equivalent level of safety.

The tow vehicle should be designed for towbarless push-back and/or maintenance towing of regional type aircraft as specified in 1.3. The design will ensure that the unit will safely secure the aircraft nose landing gear within the coupling system for any operational mode. The purpose of this towing procedure is to achieve a safer and faster operation than is possible with conventional towing equipment.

The present Aerospace Recommended Practice specifies for airplane operator and tow vehicle manufacturers the basic testing requirements for towbarless tow vehicles to be used on the nose gear of conventional tricycle type landing gears of commercial civil transport aircraft with maximum ramp weight between 8600 kg (19 000 lb) and 50 000 kg (110 000 lb), commonly designated as “regional aircraft”. Its purpose is to achieve testing results, or equivalent computer modeling, demonstrating that the loads induced by the tow vehicle will not exceed the design loads of the airplane’s nose landing gear and associated structure, reduce the certified safe life limit of the nose landing gear, or otherwise compromise the airplane’s structural integrity and airworthiness certification.

This Recommended Practice outlines the electrical performance characteristics for a continuous duty, diesel or gasoline engine driven brushless alternator unit for supplying 400-Hertz electrical power to commercial transport aircraft. It is intended to assist the airlines in standardizing recommendations for various sizes and configurations of equipment and it is a guide for the preparation of detailed specifications. The unit is primarily intended to supply power to the aircraft during passenger loading and unloading, and during servicing operations. The combination of the equipment specified herein and the interconnecting cables(s) between the 400-Hertz alternator and the aircraft shall provide power characteristics at the aircraft receptacle which meet MIL-STD-704 requirements for Category "B" equipment. Other limits which are necessary to meet specific conditions must be specified by the purchaser.
