Flightdeck Party Line Issues: An Aviation Safety Reporting System Analysis.
Abstract
This document describes an analysis of the Aviation Safety Reporting System (ASRS) with regards to human factors aspects concerning the implementation of data link into the flightdeck. The ASRS database contains thousands of reports concerning actual or potential deficiencies which may compromise the safety of aviation operations in the National Airspace System (NAS). The purpose of this study was to determine the relative frequency of errors and consequences of decisions based on incorrect information received from the party line. Detailed analysis of the reports revealed two types of errors: those attributed to incorrect transmission of party line information (14 percent error rate) and those resulting from flight crew actions/decisions based on the transmitted information (26 percent error rate). Almost half (46 percent) of the reports concerning incorrect flight crew actions were a result of executing unauthorized clearances due to similar call signs. Further analysis of the incident reports also reveals party line informational (PLI) elements that are determined useful by the flight crews. Based on the reports provided, conclusions are made with regards to the loss of the party line in a data link implementation.
