Pilot Perception of Electronic Flight Bags at Part 121 Air Carriers
Electronic Flight Bags (EFBs) have been approved for use by pilots in flight operations at many Part 121 air carriers in the United States since 2010. As an automated device replacing paper in the cockpit, there are many human factor issues that relate to operation of the EFB. EFBs have been cited …

System architecture for single-pilot aircraft in commercial air transport operations
Commercial flight operations have seen the consistent reduction of flight crew from five to two over the past several decades. As technology improves and airplanes become increasingly capable of flying themselves, this trend of crew reduction can be expected to continue. Single pilot operations in …
