Pilot Identification of Proposed Electronic Symbols for Displays of Aeronautical Charting Information

摘要

Many electronic displays of aeronautical charting information currently use different symbols for common display elements, creating the risk of confusion and misinterpretation. The SAE International Aerospace Behavior and Technology (G-10) Aeronautical Charting Committee, an industry group of subject matter experts, is developing an updated recommendations document that would provide guidance on what symbols to use on these displays. This paper describes a study conducted to evaluate some of the symbology proposed by the committee. Instrument-rated pilots were asked to identify proposed electronic symbols, and to rate their confidence in their response. The goal of this task was to determine whether pilots could correctly identify the proposed symbols, even though they may not be familiar with some of the specific symbols. Most of the symbols were well recognized, but a few were problematic.
