An electronic flight bag (EFB) is an electronic information management device that helps flight crews perform flight management tasks more easily and efficiently with less paper[1] providing the reference material often found in the pilot's carry-on flight bag, including the flight-crew operating manual, navigational charts, etc.[2] In addition, the EFB can host purpose-built software applications to automate other functions normally conducted by hand, such as take-off performance calculations.[3] The EFB gets its name from the traditional pilot's flight bag, which is typically a heavy (up to or over 18 kg or 40 lb) documents bag that pilots carry to the cockpit.[4]
