Terminology and conventions. The text of the International Standard has been approved as suitable for publi

Wherever the words “International Standard” appear, referring to this standard, they should be read as “Bri
9、tish Standard”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This doc

This will be indicated in the amendment table on the inside front cover.BS M67:1988 BSI 11-1999 1 1 Scope
11、and field of application This International Standard specifies symbols for the pictorial standardization of aircraft cargo-handling systems for unit load devices (ULDs). These symbols are applicable to all aircraft cargo-handling systems for underfloor as well as for main-deck systems. The conveyanc
12、e, guidance, restraint, power drive unit and the degree of automation for the total cargo-handling system can be depicted using the symbols. 2 Symbol system Each cargo symbol consists of a basic symbol, which represents basic functions, such as a physical function, a load direction, etc. In the draf
13、ting of the symbols account has been taken of factors such as maximum simplicity, intelligible geometry, optical similarity and good retainability. The symbols are designed to be self-explanatory, and they are used alone or in combination to generate multiple components. A symbol characterizes a com
14、ponent function, but not the detail design and manufacturing method. The standardized symbols are suitable for use with computer-aided design. All symbols are given with an explanatory description in the Table. An example of how combinations of symbols are built up is given inFigure 1. 3 Application
15、 An example of the application of some of the symbols to a typical semi-automatic underfloor cargo system for the latching and guiding of pallets and containers is given inFigure 2. Table Symbols Reference No. Component Symbol Description 1 Latch a Retractable/relocatable restraint mechanism, capabl
16、e of bearing a horizontal load perpendicular to its load-carrying side. 2 Double-acting latch a Retractable/relocatable restraint mechanism, capable of bearing a horizontal load perpendicular to both of its sides. 3 Stop a Fixed restraint, capable of bearing a horizontal load perpendicular to its le
17、ngth. 4 Vertical restraint Horizontal protrusion from the upper part of a fixed or retractable restraint, capable of bearing a vertical load. 5 Overridable Device which will cause the automatic overriding of a component in which it is incorporated. 6 Fixed guide Fixed position device, capable of gui
18、ding along its length and of bearing a horizontal load perpendicular to its length. 7 Retractable guide Retractable/relocatable position device, capable of guiding along its longest side and of bearing a horizontal load applied against its longest side. 8 Omnidirectional transfer area Panel or area
