| Abstract | Instrument approach procedure (IAP) charts can be densely packed with information. This high information density can make information difficult to find, particularly in a poorly lit cockpit during turbulence. The Voipe Center's Cockpit Hunan Factors Program conducted a series of evaluations to format IAP chart information to more closely conform to the way pilots actually use the information. All of this work has contributed to the evolution of the Voipe prototype IAP chart format. The prototype's major design features are the briefing strip and iconic missed approach procedure instructions. The briefing strip consists of three rows of tabularized information at the top of the chart. This feature is designed primarily for use in preparing for the approach. Each Information element is given in the order in which it will be used. The pilot no longer has to search through the entire chart to assemble this data. In the profile view, the "up and out" portion of the missed approach instructions is depicted in icons rather than text. This critical information is more easily located than if it were embedded in text. The objective of this study was to determine if the prototype IAP chart format would allow pilots to find information faster and more accurately during actual flight. Ten licensed pilots rated for instrument flight participated as subjects in this experiment. Each of the approaches were depicted in two chart formats: National Ocean Service (NOS) and the Voipe prototype. Pilots took advantage of the prototype's briefing strip to search for information to answer questions. They found Information faster on the prototype chart than on the NOS chart. No difference was found between the accuracy of the answers given when pilots used the prototype and when they used the H0S format. Pilots found information regarding the "up and out" portion of the missed approach instructions faster when they used the iconic missed approach instructions on the prototype chart than when they used text instructions on the H0S chart. All pilots preferred the prototype format for executing the missed approach because of the iconic instructions. Most pilots preferred the prototype format for studying for the approach. None of the pilots preferred the NOS format for executing any approach phase. |
