9、. 10 ISO 10842:2006(E) iv ISO 2006 All rights reservedForeword 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.
10、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 Internat
11、ional 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 Stand
12、ards 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 subjec
13、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10842 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 9, Air cargo and ground equipment. ISO 10842:2006(E) ISO 2006 All rights reserved vIntroduction T
14、his International Standard 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 as a vehicle for sources of utilities. In standardizing the locations of airc
15、raft service connections, they must, 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: to reduce ramp congestion and equipment interference around the
16、 aircraft, and to minimize the chance of aircraft damage from mobile GSE; to allow 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 (drainin
17、g, flushing), aircraft refuelling, and interphone (headset) connections; to standardize 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 additiona
18、l standards and parameters for mobile GSE that connects to the aircraft. It is not the intent of this International Standard 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 cha
19、racteristics 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 International Standard, either alt
20、ernative 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 ty
21、pe of aircraft. Each of these cases will result in increased aircraft servicing constraints and operating cost. 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” an
22、d, 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 alternative
23、methods to provide an equivalent level of efficiency. INTERNATIONAL STANDARD ISO 10842:2006(E) ISO 2006 All rights reserved 1Aircraft Ground service connections Locations and types 1 Scope This International Standard specifies the locations and types of aircraft ground service connections in order t
24、o optimize ground services, both fixed and mobile, for the following seven services: 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.
25、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 International Standard applies to any new type of main line comm
26、ercial transport category aircraft designed or built after its publication. In addition, it applies to any substantially modified new derivative aircraft type in the same category (derived from a previously existing type), insofar as technically and economically practical, if specified in the aircra
27、ft type specification established between customer airline(s) and manufacturer. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、craft civil passenger and/or freight transport aircraft with a maximum ramp mass over 50 000 kg (110 000 lb) 3.2 maximum ramp mass MRW maximum ramp weight maximum mass allowable for an aircraft type when leaving its parking position either under its own power or towed, comprising maximum structural
32、take-off mass (MTOW) and taxiing fuel allowance 3.3 nose landing gear NLG aircraft nose landing gear in a conventional tricycle landing gear layout 3.4 aircraft ground support equipment GSE any piece of mobile equipment, whether or not powered or self-propelled, purpose designed, built and used for
33、ground handling, servicing or field maintenance of civil transport aircraft on the ramp area of an airport 4 Requirements 4.1 General 4.1.1 The standardized ground service connections locations shall provide efficient servicing configurations in either of the two possible airport gate layouts (see F
34、igure 3). Open ramp parking, where all services are rendered by mobile GSE/vehicles. The objectives shall be to minimize ramp congestion and the possibility of servicing vehicles interfering with each other or with the aircrafts structure. Passenger boarding bridge parking, where services can be ren
35、dered either by mobile GSE/vehicles, or by fixed facilities conveyed by the bridge. The objectives shall be to minimize the length of the various cables/hoses concerned and the possibility of their interference with each other or with mobile GSE/vehicles still required. 4.1.2 All connections shall b
36、e of the type specified according to their purpose in Clauses 5 to 7 and should be placed at the locations specified according to their purpose in Clauses 5 to 7. 4.1.3 In addition, the ground service connections shall be selected in order to minimize the resulting design, weight and space occupancy
37、 penalties on board the aircraft itself. ISO 10842:2006(E) ISO 2006 All rights reserved 34.2 Location reference 4.2.1 Since the passenger boarding bridge constitutes the primary means to convey certain utilities to the aircraft, unless otherwise specified the aircraft main-deck passenger door(s) sha
38、ll be used as the reference point for the location of connections appropriate for these utilities. As a result, it is necessary to separately consider the two cases given in 4.2.2 and 4.2.3. 4.2.2 Aircraft with a single main-deck door capable of being used for passenger access located forward of the
39、 wing (see Clause 6). 4.2.3 Aircraft with two main-deck doors capable of being used (separately or simultaneously) for passenger access located forward of the wing (see Clause 7). Such aircraft can, depending on the airport gate layout, be serviced either with two passenger boarding bridges, or with
40、 one located at the most forward door (number 1L), or with one located at the most aft door (number 2L). NOTE Aircraft main-deck passenger doors are numbered 1, 2, 3, etc., from the aircrafts nose toward its tail, with index L if they are on the aircrafts left-hand side and R if they are on its righ
41、t-hand side. 4.2.4 For two utilities, electrical power supply and interphone connection, the appropriate reference point is not the passenger doors but the aircrafts nose landing gear for all aircraft (see Clause 5). 4.3 Connections height 4.3.1 With reference to the ground, the connections for all
42、services covered by this International Standard should be located, whenever the aircraft structures height allows, at a point where ground personnel can easily make connection from a standing position on the ground, without the use of ancillary access equipment. 4.3.2 The requirement in 4.3.1 applie
43、s at least to the interphone (headset) connection(s). 4.3.3 The requirement in 4.3.1 does not apply to the aircraft fuelling connections. 5 Connections locations and types (all aircraft) 5.1 Electrical power 5.1.1 As regards the location of 400 Hz electrical power connection(s), the most critical ca
44、se is considered to be aircraft towing with 400 Hz power being provided from the tractor. Accordingly, the reference point used shall be the aircrafts nose landing gear. 5.1.2 A 90 kVA connection receptacle or receptacles meeting the requirements of ISO 461-1 and ISO 461-2 (6-pin connector) shall be
45、 provided for 400 Hz electrical power. The connection(s) should preferably be vertical so as to avoid the possibility of pin misalignment under the weight of the cable. When power requirements dictate two or more connections, minimum clearance requirements shall be considered, and it shall remain po
46、ssible to perform aircraft towing using only one of the connections. 5.1.3 The connection(s) shall be located no more than 1,5 m (5 ft) from the aircrafts nose landing gear. 5.2 Interphone (headset) 5.2.1 As regards the location of ground interphone (headset) connection(s), the most critical case is
47、 considered to be aircraft towing with an interphone link being established with the tractor. Accordingly, the reference point used shall be the aircrafts nose landing gear. 5.2.2 At least two headset female connections shall be provided for interphone connection. 5.2.3 These connections shall be lo
48、cated on or left of the lower centre line of the fuselage, not more than 1,5 m (5 ft) from the aircrafts nose landing gear. ISO 10842:2006(E) 4 ISO 2006 All rights reserved5.3 Fuelling 5.3.1 A pressure fuelling connection or connections meeting the requirements of ISO 45 63 mm (2,5 in) in diameter s
49、hall be provided. 5.3.2 One or two fuelling connections should be provided on each wing, as dictated by the design minimum fuelling flow requirements and appropriate to minimize ramp congestion. 5.3.3 The fuelling connection(s) location on the wing shall be determined in order to minimize access height and the possibilities of interference with mobile GSE/vehicles performing other services on the aircraft in the course of usual cargo or passenger operations. As a general rule
