Ground Support Equipment Hydraulic Systems, Design and Installation, Recommended Practices for

2022-12-16
CURRENT
ARP4943A
This SAE Aerospace Recommended Practice (ARP) covers the design and installation requirements for hydraulic systems (up to 8000 psig [56 MPa]) for ground support equipment (GSE). This ARP is derived from AS5440, which provides hydraulic system requirements for aircraft. The recommendations herein are primarily intended for GSE that exchange hydraulic fluid with the aircraft, such as hydraulic service carts, rather than GSE with non-interfacing hydraulic systems. The GSE may be mobile, portable, or stationary.

Electrical Connectors for Use in Battery Powered Ground Support Equipment

2020-09-23
CURRENT
ARP1892B
This SAE Aerospace Recommended Practice (ARP) describes a two-pole electric connector for use in battery powered ground support equipment, i.e., traction batteries. Alternatively, the connector can have two or more auxiliary contacts for auxiliary circuits. A handle may be added as an option to assist in connecting and disconnecting.

Aircraft Markings for Ground Support Equipment Alignment

2020-04-24
CURRENT
AS6896
The purpose of this document is to provide a standard for aircraft fuselage markings located at the doors used for ground servicing operations. These markings can be used by all GSE that will dock at the aircraft. These markings may be used for one or several phases of the GSE positioning relative to the aircraft process: GSE alignment during approach, GSE final docking, and GSE auto leveling. It is not the purpose of this standard to describe the different technologies, cameras, or other equipment that can be mounted on GSE to utilize these markings. The aircraft that may use these markings will have a fuselage diameter of 3 m or more.

Design and Safety Criteria for Passenger Boarding Stairways

2012-03-28
CURRENT
ARP836C
This SAE Aerospace Recommended Practice (ARP) is broken into various categories for convenience and ease of identification. It is the purpose of this document to provide certain criteria for the design and selection of stairways, for the boarding of passengers onto an aircraft. The criteria presented are limited to those factors which affect the safety of the passengers and are coordinated, where applicable, with the practices of the architectural profession, with respect to the design of stairways. The recommended practices are applicable to both mobile variable-elevation type stairways and to fixed-elevation stairways of the type built into an aircraft fuselage.

Aircraft Maintenance Jacks - General Requirements

2011-01-14
HISTORICAL
AS4775A
This document covers the general requirements for hydraulic aircraft jacks. It can be applied to tripod, unipod, and axle jacks that may be used on open ramp areas as well as in the aircraft hanger. Throughout this Aerospace Standard, the minimum essential criteria are identified by the key word “shall”. Recommended criteria are identified by use of the key word “should”. 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 term “vertical load” throughout this Aerospace Standard is defined as the force imposed on the aircraft jack at the airframe jack point.

Ground Equipment - 400 Hertz Ground Power Performance Requirements

2011-01-14
HISTORICAL
ARP5015A
This SAE Aerospace Recommended Practice (ARP) covers the requirements for ground power equipment that supplies 115/200 V, 3-phase, 400 Hz output capable of powering aircraft type loads requiring MIL-STD-704E/DFS-400 quality power. All forms of ground power including mobile and fixed systems are addressed by this document. High voltage (270 V DC) systems are not included in this specification.

Cushion Tow Hitches Test

2006-02-09
HISTORICAL
AIR1353B
The main purpose of this test was to determine the application advantages of cushion tow hitches in comparison to the commonly used rigid tow hitch type fitted on heavy aircraft towing tractors. As diverse opinions emerged about its suitability since the introduction on the market of this new tow hitch type, it was intended to physically measure and evaluate the damping capability of this cushioned tow link when applied in practice.
