Abstract:In order to achieve potential operational and safety benefits enabled by Area Navigation (RNAV) and Required Navigation Performance (RNP) procedures it is important to monitor emerging issues in their initial implementation. Reports from the Aviation Safety Reporting System (ASRS) were reviewed to identify operational issues related to RNAV and RNP procedures. This review is part of a broader effort to understand emerging human factors issues for performance based navigation. A total of 285 relevant reports filed between January 2004 and April 2009 were identified and analyzed. For departure procedures, the majority of reports mention heading or track deviations, which are classified as “lateral” issues. For arrival and approach procedures, the majority of reports mention altitude deviations, which are classified as “vertical” issues. The track and heading issues were often associated with dropped transition waypoints in the Flight Management System (FMS). Altitude deviations during arrival and approach procedures were mainly associated with Air Traffic Control (ATC) “descend via” phraseology. The analysis shows that RNAV and RNP procedure issues are integrated with ATC operations, FMS, and procedure design issues.
