Licensed mariners carried out two simulated navigation studies testing electronic chart and information display systems (ECDIS) against paper chart navigation. In the first study, six mariners each completed approaches to Halifax, Nova Scotia, harbour with good and bad visibility and a range of wind and currents. Conditions included chart with radar, ECDIS with radar overlay and ECDIS with separate radar. ECDIS produced better performance and a smaller workload than paper charts and the radar overlay was slightly better than the separate radar display. In the second study, six new mariners completed exercises with low visibility and heavy or light radar traffic using ECDIS with radar overlay, ECDIS without overlay and ECDIS with optional overlay. Mariners preferred the optional overlay but all three conditions produced about equal performance. Based on mariners' performance and expressed preference, we recommend that ECDIS systems provide optional radar overlays.

Only two levels of adaptation are used in the most present human engineering projects of information display systems—total and contingent. At the same time experimental and theoretical analysis of the statistical relationships between structures of information display and values of psychological factors of complexity of operators' problem solving shows that three additional levels of adaptation are necessary. There are group, individual and individually—operative levels. Some mathematical methods of evaluation of optimal distribution of information displays between individuals operators, combinations of man with different individual characteristics in one operators group are worked out.

Participant Response

Electronic flight bags have become common place in commercial and general aviation flight decks. These tools provide for a compact and concise methods of carrying charts, procedure manuals, policies, and flight-related communications. On devices with connectivity, these tools can even be used to download real-time weather and file flight plans or even serve as a moving map by connecting a portable GPS receiver. However, with the proliferation of these devices, few studies have searched for any performance differences in pilots between these electronic charts and traditional paper charts. The purpose of this study was to compare pilots response time when answering a series of 30 questions related to instrument approach procedures using an electronic chart display, followed by paper charts. Twenty-seven instrument flight rated participants completed the repeated measures design using a desktop computer. The study simulated an event where the pilot’s electronic flight bag failed, and they had to use paper charts as a backup. The results of the study suggest a significant increase in participant response time when using paper charts compared to electronic ones. Participants response time using paper chart also did not significantly increase from their first trial using paper to their last trial using paper. Additional research should be completed to explore this relationship further and determine if the use of electronic charts are resulting in an unintended degradation of other pilot skills.

New System

The AN/SSN-6 Navigation Sensor System Interface (NAVSSI) Project is a new system being designed with two primary objectives; to serve as the central distribution computer for navigation data to shipboard combat/weapon systems and to serve as the electronic chart display and information system (ECDIS). The NAVSSI will operate the digital nautical chart (DNC) database being developed by the Defense Mapping Agency (DMA). Our goal is for the digital nautical chart to replace the paper chart as a legal means of ownship navigation plotting. This paper will introduce the project and will primarily explore the use of digital nautical charts for ownship navigation with NAVSSI.

Cross Track

The technology breakthrough that Electronic Chart Display and Information System (ECDIS) has brought to modern navigation has the capability to improve the safety of navigation. This could be achieved only when the capabilities of the system are known by an end-user. Cross Track Limit (XTL) is an ECDIS safety parameter, set by the navigator, which enhances the navigational task automation in the function of workload reduction. Determination of factors affecting the value of XTL safety parameter, with special consideration to chart data reliability, is elaborated in this paper. Chart data reliability depends on the quality of chart survey data, which in many cases are outdated and unreliable. Analysis of past research on this subject is used to define the factors affecting XTL. Practices of different shipping companies with regards to XTL are analyzed and compared in order to confirm if there is a uniform practice between them. Nevertheless, shipping companies have a different or no practice of obtaining XTL, which allows the navigator to define safety parameters by a subjective opinion. In this paper, method of XTL determination for a specific vessel is suggested, considering previously defined factors. Finally, crucial influence of survey data to the safety of navigation is presented in this study.

Maritime Navigation

Enhancements in shipboard automation offer the prospect of crew size reductions for navigation tasks. This work was concerned with comparing the structure of navigation tasks using paper charts with the same tasks accomplished using an electronic chart display information system (ECDIS). Voyage planning with paper charts is based on drawing specific voyage segments, measuring distances between waypoints, and annotating the chart with voyage specific information. These tasks change substantially with electronic charts, particularly in terms of how the task is accomplished. Similarly, the manual activities of track keeping are reduced, but the need for a continuous record maintains the use of the paper chart. For both navigation tasks, there is less ability to visualize geographic features continuously with electronic charts because of the keyhole effect created by a CRT display. It is concluded that the design of automated navigation aids should be based not only on the informational aspects of task performance, but also the functional means by which navigators carry out their tasks with conventional technologies such as paper charts.
