Book Description
The objective of this study was to evaluate the design features of two prototype Instrument Approach Procedure (IAP) charts. The John A. Volpe National Transportation System's 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 Jeppesen chart, and to compile the results in the form of recommendations for revision of one of the prototypes or for the design of a new lAP 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. The results showed that white the pilots were resistant to changes in approach chart design before seeing either of the prototypes, they accepted many of the new features of both prototypes and suggested additional changes after they were introduced to the new ideas. The recommendations for an improved instrument approach chart include features from both prototypes. The recommended chart design is compatible with current chart production and distribution procedures, and it is feasible to introduce it on a phased basis, changing all of the charts at any given airport at one time. It presents the information needed to brief an approach in a "Briefing Strip" at the top of the chart. This strip includes a pictorial of the Lighting to be expected on the runway being used.
