SCOPE 1.1 Purpose This document provides functional, dimensional, structural, and environmental requirements for vehicle transport devices u
11、sed to transport vehicles in wide-body aircraft. These devices are intended for use either in conjunction with NAS 3610 or AS36100 approved air cargo pallets or with specially designed and approved air cargo pallets. The unit load device (ULD) shall facilitate alteration for carriage of general carg
12、o during return haul. Pallet nets used in conjunction with existing pallets in order to restrain general cargo are also described in NAS 3610 and AS36100. The minimum essential criteria are identified by use of the word “shall“. Recommended criteria are identified by use of the key word “should“, an
13、d while not mandatory, are considered to be of primary importance in providing dependable, economical, and practical vehicle transport devices. Deviation from recommended criteria should occur only after careful consideration, extensive testing, and thorough service evaluations have shown alternate
14、methods to be satisfactory. It is the intent of this document to specify minimum air and ground handling features and to ensure interchange capability and compatibility with present and future air transport and ground handling systems. It is not the intent of this document to specify equipment desig
15、ns. 1.2 Type A, B, C The unit load devices specified herein shall be designed primarily for the transport of vehicles and alternately for the transport of general air cargo in an acceptable and profitable manner. This SAE Aerospace Recommended Practice (ARP) establishes three types of transport unit
16、s for carriage of vehicles in cargo compartments of certified civil transport aircraft. The term vehicle is used so as to encompass the possible transport of vehicles such as golf carts, light commercial vehicles, motorbikes etc. in addition to cars / automobiles. Type A (lower deck) and Type B (mai
17、n deck) will be used for carriage of one vehicle in conjunction with an air cargo pallet secured within an aircraft restraint system designed to be compatible with NAS 3610 or AS36100 approved ULDs, primarily in a random intermix with general cargo pallets. Type C (main deck) will be used, in order
18、to maximize volume utilization, for carriage of two or four vehicles as either a full or part charter operation (see Figure 1). The equipment covered by this ARP are units that interface with suitably approved / certified ULDs (typically air cargo pallets). It does not seek to bring into being any n
19、ew type of ULD, although nothing prevents a potential new ULD being developed which uses this ARP as a guide to the design process. a. Type A: Will be used for carriage of one vehicle on the lower deck of both freighter and/or passenger wide body aircraft, in conjunction with either a 60.4 in x 125
20、in (1534 mm x 3175 mm), a 88 in x 125 in (2235 mm x 3175 mm) or 96 in x 125 in (2438 mm x 3175 mm) air cargo pallets. b. Type B: Will be used for carriage of one vehicle in slanted configuration on the main deck of freighter wide-body aircraft, in conjunction with either 88 in x 125 in (2235 mm x 31
21、75 mm) or 96 in x 125 in (2438 mm x 3175 mm) air cargo pallets. NOTE: Max allowed angle for slanted car position is 40 degrees. When the vehicle is loaded lengthwise in an aircraft, the lower end must face forward to cover angle of attack at takeoff. CAUTION: The angle of the vehicle storage in the
22、transport device is to be checked as some vehicles are not permitted to be transported at a certain angle due to potential spillage or overflow of liquids (hydraulic / battery / lubricants, etc.). SAE INTERNATIONAL ARP1554D 3 OF 19c. Type C: Will be used for carriage of two or four vehicles in a dou
23、ble level configuration on the main deck of freighter aircraft, in conjunction with: 1. either NAS 3610 or AS36100 approved air cargo pallet(s) , 2. or specially designed and approved air cargo pallet(s) matching the width of vehicles in order to ensure maximum use of aircraft volume. 1.2.1 Two kind
24、s of Vehicle Transport ULDs are identified: a. general purpose vehicle ULDs, useable as a single unit or in a vehicle charter mode but with a variety of models / types fitting the geometry constraints b. dedicated vehicle ULDs designed to optimize volume and handling efficiencies with a single defin
25、ed vehicle model when used on regular charter programs. SAE INTERNATIONAL ARP1554D 4 OF 19FIGURE 1 - GENERAL ILLUSTRATION OF UNIT TYPES SAE INTERNATIONAL ARP1554D 5 OF 191.3 Design Objectives 1.3.1 Accommodate as many vehicle types and sizes as is feasible within the aircraft envelope with emphasis
26、on those most frequently shipped. 1.3.2 Ensure profitable return haul usage with general air cargo. 1.3.3 Ensure accessibility and compatibility to meet the minimum dangerous goods requirements for preparation of vehicles for shipment. 1.3.4 Protect vehicles from damage. 1.3.5 Ensure maintainability
27、 using standard high quality aerospace practices. 2. APPLICABLE DOCUMENTS The following publications form a part of this document to the extent specified herein.

REQUIREMENTS 4.1 Dimensions 4.1.1 Type A Shall adapt to a pallet length of 125 in (3175 mm) and should have an adjustable width range of 58 in
42、 (1473 mm) to 88 in (2235 mm) and/or 96 in (2438 mm). 4.1.2 Type B Shall adapt to a pallet length of 125 in (3175 mm) and should have an adjustable width of 88 in (2235 mm) or 96 in (2438 mm). 4.1.3 Type C Shall adapt to a pallet length of 196 in (4978 mm) or 238.5 in (6058 mm) and should have an ad
43、justable width range with, at least, 62.5 in (1588 mm), 88 in (2235 mm), and 96 in (2438 mm) fixed positions. 4.2 Airworthiness Approval 4.2.1 The unit together with its base pallet shall be approved for installation in the aircraft type(s) for which it is intended 4.2.2 The unit together with its b
44、ase pallet shall meet all the applicable requirements of the approved Weight and Balance Manual(s) of this (these) aircraft type(s) 4.2.3 Airworthiness requirements compliance can be achieved in one of two ways: a. Where possible, through the base pallet being approved under TSO C90 in reference to
45、AS36100 or NAS 3610, with the units structure being considered as a palletisation accessory (see ARP5486 para 8.4.1 and 8.4.3), subject to all the following conditions being met: no modification of the base pallet as approved The loads imposed on the pallet edge rails by securing the loaded unit sha
46、ll not exceed the capability of the pallet edge rail. These loads shall be applied to the edge rail at positions either the same as those defined for net attachment in the pallets TSO C90 airworthiness approval, or as close as possible to such defined points. SAE INTERNATIONAL ARP1554D 8 OF 19Note a
47、ircraft pallet nets are not generally recommended for restraining vehicles, and any tie-down straps (general purpose or purpose built) used as primary restraints shall meet the requirements of AS5385C (ISO 16049-1). compliance with the intended aircraft(s) maximum area load, running load, and ULD C-
48、of-G range at the intended aircraft positions. NOTE: This usually requires stiffening / load spreading members to be part of the devices structure. b. Where the pallet cannot be, or remain, TSO approved (e.g. due to its being a special size, the pallets approval becoming invalid due to modification
49、of the pallet, or the device being permanently attached to the base pallet such that the whole consitutes an integral unit). Under these circumstances, the whole unit must be approved under a STC or alternative approval procedure (see ARP5486 para 8.4.2) 4.3 Construction 4.3.1 Units shall be rugged, weatherproof, and lightweight. 4.3.2 Components shall not permit liquids, sand, or debris to accumulate within. 4.3
