Abstract : Instrument approach procedure (ZAP) charts play a large rote in contributing to the success or failure of approaches and landings. Paper ZAP charts have been criticized for excessive clutter, for text sizes that are too small to read, and for inadequate terrain representation.The electronic presentation of approach information may counteract these criticisms by providing automatic or pilot controlled filtering of the information displayed. However, without careful attention to human factors issues early in the design and development of electronic ZAPs (EZAPs), new problems may result. The goal of this project was to develop preliminary guidelines for designers and certifiers of EZAPs to assure that EZAPs help rather than hinder pilots during approach and Landing. To identify potential human factors problems in the design of EZAPs, current paper ZAP charts and the instrument approach task were studied. Pilots were interviewed and Literature describing the information requirements of the task and the cognitive implications of the task were reviewed. A cognitive task analysis was performed. Specific features and functions were identified that may be beneficial to an EZAP. Literature was reviewed in the areas of cognitive psychology, human-computer interaction, and aviation to identify design concepts and principles for the design of these features and functions. Guidelines were developed from the design concepts and principles and, finally, prototypes of EZAPs were designed in accordance with the new guidelines.
