Evaluation of Prototype Air Carrier Instrument Approach Procedure Charts

摘要

The objective of this study was to evaluate the design features of two prototypeInstrument Approach Procedure (IAP) charts. The John A. Volpe National Transportation Systems Center in cooperation with the Air Transport Association's Chart and Data Display Working Group prepared one of the prototypes, and the other was produced by Jeppesen Sanderson. The study was designed to compare each prototype to the current Jeppensen, and to compile the results in the form of recommendations for revision of one of the prototypes or for the design of a new IAP chart. Pilots' opinions of the speed and accuracy with which they could acquire and use the information shown and their preferences for the unique features of each were the primary evaluative measures. Scaling techniques were used to obtain the pilots' opinions, preferences and assessments of each chart's suitability for use in approach briefing, normal approach, and go-around. A total of 91 air carrier pilots from four airlines operating under Part 121 of the Federal Aviation Regulations took part in the study.
