High Quality Content by WIKIPEDIA articles! 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. It is a general purpose computing platform intended to reduce, or replace, paper-based reference material often found in the Pilot`s carry-on Flight Bag, including the Aircraft Operating Manual, Flight Crew Operating Manual, and Navigational Charts (including moving map for air and ground operations). In addition, the EFB can host purpose-built software applications to automate other functions normally conducted by hand, such as performance take-off calculations.
