Vehicle Transport Unit Load Device (ULD)
Description / Abstract:
Purpose
This document provides functional, dimensional, structural, and environmental requirements for vehicle transport devices used 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 cargo 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", and 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 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 designs.
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 units 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 (main 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 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 new 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 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 3175 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 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.).
c. Type C:
Will be used for carriage of two or four vehicles in a double 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.
Two kinds 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 defined vehicle model when used on regular charter programs.
