Safety events in which Electronic Flight Bags (EFBs) were a factor are reviewed. Relevant reports were obtained from the public Aviation Safety Reporting System (ASRS) database and the National Transportation Safety Board (NTSB) accident report database. Of the 67 relevant ASRS reports identified, 32 pertain to use of chart software and 30 pertain to computation of flight performance. Operational outcomes/anomalies and underlying EFB issues are identified. Charts were often in use on the EFB when deviations in heading, altitude, or speed occurred. Zooming and panning the chart display can induce workload and may cause the pilot to miss important information. With flight performance calculations, anomalies included company policy deviations, incorrect computations, and runway incursions. Finally, some pilots who were new to the EFB mentioned that difficulty using the EFB contributed to the event. EFB-related findings from two NTSB accident reports are highlighted. Both of these identified use of an EFB for calculating landing distance as a contributing factor. One issue was that assumptions underlying the performance calculations on an EFB must be presented to the crew as clearly as on paper-based performance tables. A second issue was assessment of the adequacy of training and procedures for using EFB performance calculations functions.
