Electronic Flight Bag (EFB)

Definitions

• An electronic display system intended primarily for flight deck or cabin use. EFB devices can display a variety of aviation data or perform basic calculations (e.g., performance data, fuel calculations, etc.). In the past, some of these functions were traditionally accomplished using paper references or were based on data provided to the flight crew by an airline’s flight dispatch function. The scope of the EFB system functionality may also include various other hosted databases and applications
• A portable or integrated device that allows the pilot to carry all necessary aeronautical and performance data, weight and balance, and aircraft checklists in digital form and may allow remote manipulation of the avionics through wireless radio connections.
