Aircraft Ground Air Conditioning Service Connection

2022-09-30
CURRENT
AS4262B
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.

Passenger Access Means Docking Indicator for Cabin Crew

2022-05-02
CURRENT
AS7995
This SAE Aerospace Standard describes the system used by passenger boarding stairs (PBS) mobile passenger boarding ramps (PBS) and boarding bridges (PBB) to inform on-board cabin crew about the docking status of the PBS/PBR/PBB and whether it is positioned such that it is safe to open the aircraft door. Current practice calls for the PBS/PBR/PBB operator to knock on the aircraft door to inform the cabin crew that it is safe to open the aircraft door. New technologies being incorporated into PBS/PBR/PBB such as remote control systems and autonomous driving vehicles are entering the market. As such, new/updated controls and/or procedures are necessary to ensure continuing safe operations.

Aircraft Ground Service Connections Locations and Type

CURRENT
ARP4084B
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:

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.

Nose Gear Towbarless Tow Vehicle Basic Test Requirements

2012-09-24
HISTORICAL
ARP5283A
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.

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.

Nose Gear Towbarless Tow Vehicle Basic Test Requirements

2005-02-10
HISTORICAL
ARP5283
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.

ARP760
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.

ARP1348A
This SAE Aerospace Recommended Practice (ARP) applies to airline trailer equipment with four wheel running gear pulled and steered through an integral tow bar, for use on airport ramps and other airport areas for transporting baggage, freight, and other materials. This ARP can apply to any airline/airport trailer chassis regardless of its equipment; the trailer bed can be designed to carry either bulk baggage/cargo, or a cargo unit load device by means of a rollerized conveyor system, or a piece of aircraft servicing equipment (e.g., ground power unit, air start unit, etc.).
