Abstract : This document presents a general methodology for developing Airway Facilities (AF) symbols and provides guidelines for the coding of visual symbols and auditory signals. Coding refers to the characteristics of a symbol that developers can change to improve its interpretation or message content. These coding guidelines should not be considered exhaustive but rather represent a compilation of the most important items to consider when developing visual or auditory symbols. The decision to use a visual symbol, an auditory signal, or both, will depend on the nature of the displayed information, operational conditions, and users requirements. A list of questions for determining the best coding technique is provided. AF symbols represent facilities, equipment, services, and status information such as alarms and alerts. These guidelines also provide a systematic methodology for developing symbols that will help in the creation and testing of effective symbols.
