NOTE: EUROCAE ED-76A is equivalent to RTCA/DO-200A.

4. DEFINITIONS. The following definitions are specific to this AC and may differ with those definitions contained in other published references.

a. Electronic Flight Bag (EFB). An electronic display system intended primarily for cockpit or cabin use. EFB devices can display a variety of aviation data (e.g., checklists, navigation charts, pilot’s operating handbook (POH)) or perform basic calculations (e.g., performance data, fuel calculations). The scope of the EFB system functionality may also include various other hosted databases and applications. Physical EFB displays may be portable (Class 1), attached to a mounting device (Class 2), or built into the aircraft (Class 3).

b. Electronic Chart Display (ECD). A display device that presents a comprehensive depiction of interactive information and/or precomposed information that is the functional equivalent of a paper aeronautical chart. An ECD may be a device installed in the instrument panel of an aircraft or a portable device. (ICAO, Annex 4, Chapter 20.) An ECD is not a multi-function display (MFD) that is permanently installed into an aircraft that is designed under a technical standard order (TSO). However an MFD may incorporate databases that depict checklists, navigation charts, POH, etc.

c. Precomposed Information. Information that is previously composed into a static, composed state (non-interactive). The composed displays have consistent, defined, and verifiable content, and formats that are fixed in composition.

d. Interactive Information. Information presented on the EFB or ECD that, via software applications, can be selected and rendered in a number of dynamic ways. This includes variables in the information presented based on data-oriented software algorithms, concepts of decluttering, and “on-the-fly” composition as opposed to precomposed information.

5. BACKGROUND. Operators have long recognized the benefits of using portable electronic devices (PED), such as commercially available portable computers, to perform a variety of functions traditionally accomplished using paper references. EFB systems may be used in conjunction with, or to replace, some of the paper reference material that pilots typically carry in the cockpit. EFBs can electronically store and retrieve information required for flight operations, such as the POH and supplements, minimum equipment lists, weight and balance calculations, aeronautical charts and terminal procedures. EFB systems are being developed to support functions during all phases of flight operations. Refer to AC 120-76A for complete details for installation of an EFB.
