Electronic Depiction of Instrument Approach Procedure (IAP) Charts. Developmentand Evaluation. Phase 1. Preliminary

摘要

This report describes the research program being conducted at the Volpe NationalTransportation Systems Center on the development of electronic aeronautical charts. The design of electronic aeronautical navigation charts raises many interrelated human factors issues including those pertaining to the physical aspects of the display screens (e.g., location in the cockpit, screen resolution, color capability, brightness range) and those affecting the piLot interaction with the software (i.e., pilot interpretation of the information presented). A limited amount of research has been conducted on the design of electronic chart systems for instrument approach procedure (IAP) charts. The results have indicated that not all of the information printed currently on paper IAP charts is needed to fly instrument approaches. Current issues in electronic chart design are discussed in this report. Results from a study that compared three alternative design formats are also provided. Based on the findings from this study, it was determined that electronic charts are a benefit to pilot situation awareness. Newer design formats that use small amounts of display space are also presented.
