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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 27470 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 9, Air cargo and ground equipment.
Introduction
This International Standard specifies the minimum functional, performance and safety requirements to be
taken into account by manufacturers for the design of catering vehicles intended to service the upper deck of
very large capacity aircraft. It identifies the various concerns to be taken into consideration to ensure vehicle
safety for operators and aircraft.
Throughout this International Standard, 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 safe, economical and usable aircraft catering vehicles.
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.

INTERNATIONAL STANDARD ISO 27470:2011(E)

Aircraft ground equipment — Upper deck catering vehicle —
Functional requirements
1 Scope
1.1 This International Standard specifies the minimum functional, performance and safety requirements for
a catering vehicle capable of transporting and loading/unloading in-flight service (catering) equipment and
supplies into or from the upper deck of very large capacity aircraft, as well as the main deck of these or other
aircraft types.
1.2 The intent of this International Standard is not to specify equipment design, but rather to define
minimum functional and performance requirements and highlight those criteria which are known to be
essential to an efficient and safe operation on civil transport aircraft in the environment of international airports.
1.3 This International Standard specifies the worldwide requirements recognized by aircraft and vehicle
manufacturers as well as airlines and catering agencies. In addition, it shall be applied with due reference to
the national governmental regulations of the country where the vehicle is to be operated. The main though not
exclusive areas in which such national regulations may apply are:
⎯ general requirements applicable to road vehicles;
⎯ sanitary requirements regarding design, cleaning and disinfection of vehicles used to carry food for
human consumption;
⎯ stability and other safety requirements applicable to elevating equipment carrying personnel in the
elevated position.
Nothing in this International Standard, however, shall be deemed to supersede any locally applicable law or
regulation, unless a specific exemption has been obtained for this purpose from the appropriate Authority.
1.4 Certain requirements of this International Standard are specifically dictated by overwing access to doors
of certain aircraft types, and may not apply to other aircraft types. However, the intent of this International
Standard is that any upper deck catering vehicle shall be capable of safely handling this specific situation.

accordingly meet all applicable requirements of ISO 10841.
3.1.3 The vehicle's dimensions, laden weight and other characteristics shall satisfy all the applicable
government regulations for vehicles to be used on public roadways.
3.1.4 The vehicle shall be equipped with a fully enclosed elevating van body with a front platform, capable
of reaching heights between 2,54 m (100 in) and 8,40 m (330 in) above the ground.
3.1.5 The allowable load capacity in the elevating van body should be no less than 3 500 kg (7 700 lb). A
4 500 kg (10 000 lb) load capacity is recommended, consistent with the number of standard trolleys
(see 3.3.1) required.
3.1.6 The vehicle's driver shall have maximum unobstructed view of the platform and aircraft interface or
potential interference areas (e.g. engines, wing) under all operating conditions. Particularly, for final
positioning to the aircraft at walking speed, the driver's position while at the steering wheel shall provide a free
upward line of sight towards these critical areas. This visibility field may be achieved through appropriate
window section(s), equipped with wiper and defrosting, in the cab's roof, and either:
a) the front platform in its fully retracted position leaving the visibility field unobstructed; or
b) the front platform being raised enough during final positioning to leave the visibility field unobstructed.
3.2 Overall dimensions
3.2.1 The overall height of the vehicle in the fully lowered position shall not exceed 4,00 m (157 in), in order
to be compatible with standard airport infrastructure.
3.2.2 The van floor's height in the fully lowered position should not exceed 1,62 m (64 in) for docking.
3.2.3 The overall width of the vehicle in a driving condition (with stabilizers retracted) should meet locally
applicable governmental regulations.
3.2.4 The overall plan view dimensions of the vehicle shall be kept to a minimum, consistent with intended
payload (see 3.3.1). In order to facilitate main deck use on aircraft other than very large capacity ones, it is
recommended that the vehicle's overall length should preferably not exceed 12,20 m (40 ft).
3.2.5 The vehicle's overall swept turning radius shall be kept to a minimum, and should preferably not
exceed 12,20 m (40 ft).

overhanging capability and continuous staff and trolley access to any aircraft upper or main deck door. The
platform floor shall provide an anti-slip surface throughout its whole area.
3.4.2 The geometry of movable platform(s) shall be such as to adequately accommodate the safe opening
and closing of upper deck doors, but also provide a standard interface with main deck doors. Steps at
junctions between platforms shall not exceed a height of 25 mm (1,0 in), and shall include a ramp at an angle
not exceeding 15° with the horizontal plane, in order that handling of trolleys be as smooth as possible.
3.4.3 A safe operator position shall be provided on either the fixed part of the platform or the forward part of
the van body to allow direct visibility of the aircraft interface area during vehicle positioning. It shall be within
reach of the upper control panel (see 5.2) and protect the operator against risk of falling while the platform's
movable part(s) and corresponding guardrails or side panels are not yet in the extended and locked-in position.
3.4.4 In order to prevent the hazards that can result from handling heavy items high above the ground
without a safeguard, all movements of movable platforms should be powered and controlled from the upper
control panel (see 5.2).
3.4.5 In order to facilitate positioning at the interface with aircraft upper deck doors at night and under poor
visibility conditions, an adequate working light shall be provided on the platform or forward exterior face of the
van body, to provide the platform and aircraft interface area with a minimum illumination of 200 lx (18,5 ft-
