The Effect of Electronic Flight Bag Use on Pilot Performance during an Instrument Approach

Abstract

For years, paper-based navigation aids have been an integral part of safely operating an aircraft. While these tools have served their purpose well, the technology to replace them with a more productive and efficient device may have arrived. Electronic Flight Bags (EFBs) have quickly become popular for both commercial and private use. This study analyzed the effect EFBs have on pilot performance in a single pilot environment by evaluating the performance of instrument rated pilots at a large  southeastern flight school. The participants (N=14) were asked to complete two instrument approaches in a flight training device. One approach was executed using an Apple iPad® equipped with ForeFlight™ software (the EFB), while paper charts were utilized during the other approach. Deviations in altitude, heading, airspeed, and localizer course from instrument pilot practical test standards were recorded, as was the  time taken for each participant to configure the approach. Statistical  analysis was conducted to determine if a difference existed between the two methods. The results showed a statistically significant increase in every analyzed performance metric when using the EFB. A survey of participants’ perceived workload during the approaches was also conducted, which  revealed participants felt using the EFB decreased their workload.
