BS ISO 11532:2018,Aircraft ground equipment – Graphical symbols.The size is 3.1M.You can download BS ISO 11532:2018 pdf file here.
This document is a compendium of all graphical symbols generally used on aircraft ground support equipment. Included are relevant symbols used in the automotive industry, as standard commercial chassis often form part of the equipment.
Manufacturers are encouraged to select those symbols needed for the type(s)vof equipment they produce. Users of equipment can also take an excerpt from the content of this document for staff training purposes depending on the equipment concerned.
BS ISO 11532:2018 establishes common graphical symbols for use on all types of aircraft ground support equipment.
They have been compiled for the benefit of those who deal with such equipment, such as airlines, airport handling agencies, airport authorities, manufacturers, etc., in order to facilitate fast and accurate identification of controls, indicators and decals of powered and unpowered equipment.
The presentation of this document is based on the recommendations of ISO/TC 145, Graphical symbols.
BS ISO 11532:2018 is also intended to promote standardization of terms for controls, indicators, etc. for aircraft ground support equipment and alleviate language problems.
These graphical symbols are intended to be placed on all new equipment and retrofitted on all existing equipment as far as possible.
4 General requirements
The symbols shall be as given in Clause 5, except for any deviations necessary to reproduce an accurate representation of the driver’s or operator’s line of sight. All symbols required are listed in Clause 5 and most are defined in ISO 7000.
Symbols on controls and tell-tales shall contrast well with their background (preferably light symbols on a dark background).
The symbols and tell-tales shall be recognizable by the driver or operator from his usual position without causing hazard or unavoidable stress.
On equipment directly docking onto aircraft, the slow docking speed shall be identified in opposition to travel speed by the”turtle”(20.09.07.52)and”hare”(20.09.07.53)symbols defined in ISo 3287, and the very slow final docking speed shall be identified by the”snail”symbol(20.09.07.54)
The corresponding speed ranges shall be as specified in ISO.
