s 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.

The EFB gets its name from the traditional pilot's Flight Bag, which is typically a heavy (up to 40 lb/18 kg or more) documents bag that pilots carry to the cockpit. The Electronic Flight Bag is the replacement of those documents in a digital format. EFB weights are typically 1 to 5 pounds (0.5 to 2.2 kg), about the same as a laptop computer, and a fraction of the weight and volume of the paper publications. There are numerous benefits for using an EFB but specific benefits vary depending on the size of the operation, type of applications used, the existing content management and distribution system, the type of applications deployed. Some common benefits include: weight savings by replacing the traditional flight bag, reduced medical claims from handling traditional flight bags, reduced cost, and increased efficiency by reducing or eliminating paper processes. There are also claims of increased safety and reducing pilot workload.

According to the FAA's Advisory Circular (AC No. 120-76A), an Electronic Flight Bag is an electronic display system intended primarily for cockpit

/flightdeck or cabin use.

There are also militarized variants, with secure data storage, night vision goggle compatible lighting, environmental hardening, and military specific applications and data.

EFB devices can display a variety of aviation data or perform basic calculations (including performance data and fuel

 calculations.). 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" crew.

For large and turbine aircraft, FAR 91.503 requires the presence of navigational charts on the airplane. If an operator's sole source of navigational chart information is contained on an EFB, the operator must demonstrate the EFB will continue to operate throughout a decompression event, and thereafter, regardless of altitude. The only way to achieve this capability is by using a Solid State Disk drive or a standard rotating mass drive in a sealed enclosure.

History

The earliest EFB precursors came from individual pilots in the early 1990s who used their personal laptops and common software (such as Spreadsheets and Word Processing applications) to perform such functions as weight & balance calculations and filling out operational forms. One of the earliest and broadest EFB implementations was in 1991 when FedEx deployed their Airport Performance Laptop Computer to carry out aircraft performance calculations on the aircraft (this was a commercial off-the-shelf computer and was considered portable). In addition, FedEx also began deploying Pilot Access Terminals on their airplane in the mid-1990s. These later devices were common laptops that used a certified docking station on the airplanes (to connect to power and data interfaces). In 1996, Aero Lloyd

JetBlue took a different approach by converting all of its operations documents to electronic format and distributing them over a network to laptop computers that were issued to pilots (versus to the airplane).

 airline) became the first to deploy an electronic tech log using GPRS communication, replacing the paper process. Thomas Cook has several years of successful operational experience of an EFB focussed on its UK fleet.

As personal computing technology became more compact and powerful, with extensive storage capabilities, these devices became capable of storing all the aeronautical charts for the entire world on a single three-pound (1.4 kg) computer, compared to the 80 lb (36 kg) of paper normally required for worldwide paper charts. New technologies such as real-time satellite weather and integration with GPS have further expanded the capabilities of Electronic Flight Bags. However, for large commercial airlines, the primary problem with EFB systems is not the hardware on the aircraft, but the means to reliably and efficiently distribute content updates to the airplane.

While the adoption rate of the Electronic Flight Bag technology has been arguably slow among large scheduled air carriers, corporate operators have been rapidly deploying EFBs since 1999 due to reduced regulatory burden and easier cost justification.

Hardware classes

Electronic Flight Bags are divided into three hardware classes and three software types.
Reference FAA Order 8900.1 FAA Inspector Handbook Guidance on FSIMS for the most recent and accurate descriptions:

EFB hardware classes include:
  • Class 1 - Standard commercial-off-the-shelf (COTS) equipment such as laptops or handheld electronic devices. These devices are used as loose equipment and are typically stowed during critical phases of flight. A Class 1 EFB is considered a Portable Electronic Device (PED). Class 1 EFBs may be used to display Type B applications in critical phases of flight provided that they are 'secured and viewable'.

  • Class 2 - Also Portable Electronic Devices, and range from modified COTS equipment to purpose-built devices. Mounting, power (ship's power as primary) or data connectivity of an EFB typically requires the application of an STC, Type Certificate or Amended Type Certificate. (ref: FAA Order 8900.1)

  • Class 3 - Considered "installed equipment" and subject to airworthiness requirements and, unlike PEDs, they must be under design control. The hardware is subject to a limited number of RTCA DO-160

     requirements for software, but this depends on the application-type defined in the Advisory Circular. Class 3 EFBs are typically installed under STC or other airworthiness approval.

Applications

The EFB may host a wide array of applications, categorized in three software categories
(Reference AC 120-76 as amended, for an actual list of examples):

    • Static applications, such as document viewer (PDF, HTML

      system


Note: Type C applications are subject to airworthiness requirements, such as software certification. Type C applications must run on Class 3 EFB.

Regulations

According to the FAA, Class 1, Class 2 and Class 3 EFB may act as a substitute for the paper manuals that pilots are otherwise required to carry with them. While Part 91 Operators (those not flying for hire, including private and corporate operators) can use their Pilot In Command (PIC) authority to approve the use of Class 1 and Class 2 EFBs (which are PEDs), operator with OpSpecs (Part 135, Part 121) must seek operational approval through the OpSpecs process.

EFB users and installers should be aware of recent, clarified guidance for FAA Inspectors. Draft guidance pertaining to EFB operational authorization and airworthiness/certification requirements is maintained by the FAA.

Clarifying the intent of FAA Advisory Circular AC 120-76A, new draft inspector handbook guidance includes the following requirements:
  • PEDs used in a Class 1 or Class 2 configuration must meet the rapid decompression testing requirements of standard RTCA DO-160E.
  • Any data connectivity of PEDs used in a Class 1 or Class 2 configuration to aircraft systems shall be performed in accordance with a Supplemental Type Certificate, Type Certificate or Amended Type Certificate.
  • Any mounting or attachment of PEDs used in a Class 1 or Class 2 configuration to the aircraft shall be performed in accordance with a Supplemental Type Certificate, Type Certificate or Amended Type Certificate.
  • Electronic chart software: The display of own-ship position ('spotter') on the ground must meet the requirements of AC 20-159 and/or TSO C-165.
  • Electronic chart software: The display of own-ship position in flight is prohibited on Class 1 or 2 configurations.

Available EFB systems

FAA rule 91.21 prohibits wireless and cellular electronics in aircraft while taxing and in the air. 91.21 does allow pilots in command to allow non-transmitting devices in aircraft, but only after the PIC tests it under the guidelines of FAA 91.21(6).

There are many software options to create your own EFB, but most are made for T-PEDs, and as stated above, are prohibited in aircraft.

GPS are not EFBs, they are GPS. EFBs have on them the materials you are required to have in your aircraft, that replace your flight bag of materials.
