This SAE Aerospace Information Report (AIR) considers the following major areas: 1 major components and their ratings; 2 selection criteria for optimum design balance for electrical systems; 3 effects of operating conditions and environment on both maintenance and life of components; 4 trouble signals - their diagnosis and cure.

This SAE Aerospace Recommended Practice (ARP) applies to the air delivery systems such as flexible ducting, aircraft connectors, TAD tubes, and hose management systems for Pre-Conditioned Air Equipment (central systems, point of use systems, and mobile units) used on commercial aircraft. This standard will establish minimum performance requirements and a method to test the performance of the entire air delivery system in three areas: 1) air tightness 2) temperature losses and 3) energy losses.

This SAE Aerospace Recommended Practice (ARP) outlines the basic general design requirements for ground support equipment used in the civil air transport industry. It is intended to assist in standardizing requirements for various configurations of equipment. For procurement of equipment, sections of this document should be specified with due consideration of the functional and environmental requirements of the equipment, and to the relative cost of satisfying those requirements.

This SAE Aerospace Recommended Practice (ARP) describes the standards on telemetry data retrieval on ground support equipment (GSE), focusing on wiring requirements, connectors, signal definitions and communication protocols applicable in the industry.

This document outlines the functional and design requirements for baggage/cargo tow tractors used for airline services.

This SAE Aerospace Information Report (AIR) 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. Comprehensive design requirements for passenger stairs can be found in the industry documents listed under 2.1.3, 2.1.4, and 2.1.5 hereafter. 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.

This SAE aerospace recommended practice (ARP) covers the requirements for external ground power equipment supplying 115/200 V, three-phase, 400 HZ output power measured at the aircraft receptacle. All forms of 400 Hz ground power including mobile and fixed systems are addressed by this document.

The tow vehicle should be designed for towbarless movement of aircraft on the ground. The design will ensure that the unit will safely secure the aircraft nose landing gear within the coupling system for any operational mode.

This SAE Aerospace Information Report (AIR) identifies and summarizes the various factors that must be considered and evaluated by the design or specifying engineer in establishing the specifications and design characteristics of battery-powered aircraft tow tractors. This AIR is presented in two parts. The first part is simply a summarization of design factors that must be considered in establishing vehicle specifications and design characteristics. The second part refers particularly to the performance characteristics of an aircraft tow tractor. Some definitions, formulas, data, and an example are provided mainly for assisting the specifying engineers of potential buyers and users of aircraft tow tractors in the evaluation and comparison of their requirements with the performance capabilities of the various tow tractors offered by the tow tractor manufacturers.

This SAE Aerospace Recommended Practice (ARP) describes three general types of Ground Support Equipment (GSE) battery chargers. The battery charger typically requiring up to 8 hours to recharge a 100% discharged battery, hereafter called “Conventional Charger.” A charger, hereafter called “Opportunity Charger,” which has the ability to charge at a slightly faster rate than a conventional charger. A charger, hereafter called “Fast Charger,” which has the ability to charge at a much faster rate than a conventional charger. Recommendations that apply to all types will refer generically to “charger.”

This SAE Aerospace Information Report (AIR) provides information about impulse loads that occur during normal aircraft towing operations. An instrumented tow bar was used to characterize towing loads. Suggestions to minimize impulse loads by reducing the tow bar to tow vehicle gap are described.

This SAE Aerospace Recommended Practice (ARP) outlines the functional and design requirements for a b self-propelled belt conveyor for handling baggage and cargo at aircraft bulk cargo holds. Additional considerations and requirements may legally apply in other countries. As an example, for operation in Europe (E.U. and E.F.T.A.), the applicable EN standards shall be complied with.

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.

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 Recommended Practice (ARP) covers the design and installation requirements for hydraulic systems (up to 8000 psig [56 MPa]) for ground support equipment (GSE). The GSE may be portable or stationary.

This SAE Aerospace Standard (AS) defines interface configurations for the ground air conditioning service connection on commercial transport aircraft. In addition, it defines the clearances required to accommodate the connection of ground air conditioning hose couplings. Two types of service connections are included. The Type A connection (Figure 1) is a slotted ring with integral locking pads and is comparable to the MS33562 connection. The Type B connection (Figure 2) is a flanged tube with external locking lugs (Figure 3). The Type B connection has the same interface dimensional requirements as the Type A connection.

This document describes:

The provisions of this standard cover minimum performance requirements and design parameters for Preconditioned Air units (PCA) devices supplying air the aircraft cabin. It identifies the need for interim and future performance improvement for ground equipment delivery systems, to meet industry requirement for reducing airborne compounds or particulates (“source types”) in aircraft cabin and flight deck.

Incidents where a piece of ground support equipment or personnel damages an aircraft under the control of ground or maintenance operations that requires corrective action by aircraft maintenance personnel. Operations include, but are not limited to servicing, line maintenance, heavy maintenance, and aircraft movement, e.g., marshalling/pushback/tow/reposition/taxi.
