Aircraft — Ground service connections — Locations and types

ISO 10842:2017 specifies the locations and types of aircraft ground service connections in order to optimize ground services both fixed and mobile, for the seven different services hereafter: - 400 Hz electrical power; - preconditioned air for cabin conditioning; - pneumatic power for jet engine start; - potable water; - lavatory service (draining, flushing); - aircraft refuelling; - interphone (headset) connections. It focuses on these aircraft services because: - these connections are those most frequently used during aircraft airport turnaround operations; - in terms of economic benefit, they have the greatest impact through improved efficiency. ISO 10842:2017 is intended to apply to any new type of main line commercial transport category aircraft designed or built after its publication. In addition, it is expected that any substantially modified new derivative aircraft type in the same category (derived from a previously existing type) will, insofar as technically and economically practical, meet the requirements of this document, if specified in the aircraft type specification established between customer airline(s) and manufacturer. It is not the intent of this document to restrict in any way the basic design of any future types of civil passenger transport aircraft. It aims, however, at clarifying for aircraft design engineers the design characteristics which would make it difficult or impossible for a new type of aircraft to be adequately serviced from existing airport facilities. Should basic aircraft design requirements impose on a future model certain characteristics not complying with the present document: - either alternative methods of servicing the aircraft will have to be implemented; or - existing facilities in the airports where such a new type of aircraft is to operate will require some degree of modification/rework; or - additional interface devices/equipment will be required in order to service such a new type of aircraft; in either case resulting in increased aircraft servicing constraints and operating cost.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
This document specifies standardized locations and types of main line transport aircraft ground
service connections to accommodate the growing trend toward fixed systems which use the passenger
boarding bridge and/or underground “pop-up” or pit systems as a vehicle for sources of utilities. In
standardizing the locations of aircraft service connections, they should, however, continue to be served
efficiently in those instances where mobile ground support equipment (GSE) is used.
The objectives of standardizing the locations of aircraft servicing connections are:
— reducing ramp congestion and equipment interference around the aircraft, and minimizing the
chance of aircraft damage from mobile ground support equipment (GSE);
— allowing for optimization of ground services, both fixed and mobile, specifically 400 Hz electric
power, preconditioned air for cabin conditioning, pneumatic power for jet engine start, potable water,
lavatory service (draining, flushing), aircraft refuelling, and interphone (headset) connections;
— standardizing the locations of service points around the aircraft to allow airport planners and
facility engineers to design fixed servicing systems to serve all aircraft easily and efficiently, as well
as to provide additional standards and parameters for mobile ground support equipment (GSE) that
connects to the aircraft.
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 serviceable, economical and practical aircraft
ground service connections layouts. Deviation from recommended criteria should only occur after
careful consideration and thorough service evaluation have shown alternate methods to provide an
equivalent level of efficiency.

INTERNATIONAL STANDARD ISO 10842:2017(E)
Aircraft — Ground service connections — Locations and
types
1 Scope
This document specifies the locations and types of aircraft ground service connections in order to
optimize ground services both fixed and mobile, for the seven different services hereafter:
— 400 Hz electrical power;
— preconditioned air for cabin conditioning;
— pneumatic power for jet engine start;
— potable water;
— lavatory service (draining, flushing);
— aircraft refuelling;
— interphone (headset) connections.
It focuses on these aircraft services because:
— these connections are those most frequently used during aircraft airport turnaround operations;
— in terms of economic benefit, they have the greatest impact through improved efficiency.
This document is intended to apply to any new type of main line commercial transport category aircraft
designed or built after its publication.
In addition, it is expected that any substantially modified new derivative aircraft type in the same
category (derived from a previously existing type) will, insofar as technically and economically
practical, meet the requirements of this document, if specified in the aircraft type specification
established between customer airline(s) and manufacturer.
It is not the intent of this document to restrict in any way the basic design of any future types of civil
passenger transport aircraft. It aims, however, at clarifying for aircraft design engineers the design
characteristics which would make it difficult or impossible for a new type of aircraft to be adequately
serviced from existing airport facilities. Should basic aircraft design requirements impose on a future
model certain characteristics not complying with the present document:
— either alternative methods of servicing the aircraft will have to be implemented; or
— existing facilities in the airports where such a new type of aircraft is to operate will require some
degree of modification/rework; or
— additional interface devices/equipment will be required in order to service such a new type of
aircraft;
in either case resulting in increased aircraft servicing constraints and operating cost.
