Electronic Flight Bag (EFB)

The Electronic Flight Bag (EFB) is an electronic storage and display system designed to replace traditional paper products in the cockpit.  EFB devices can also store and display a variety of aviation data or perform calculations such as performance and weight and balance considerations. 

The use of an EFB introduces a wide variety of hazards and risk that must be carefully managed.

Contrary to common perception, the application process for use of a Class 3 EFB on M-Registered aircraft is considerably simpler than a Class 1 EFB and requires less supporting documentation. The IOMAR encourages operators to take advantage of the full functionality of Class 3 EFBs where possible.

The Isle of Man Aircraft Registry is required to “establish criteria for the operational use of EFB functions to be used for the safe operation of aeroplanes/helicopters” and ensure that:

  • The EFB equipment and its associated installation hardware, including interaction with aeroplane/helicopter systems (if applicable) meet the appropriate airworthiness certification requirements.
  • The operator/owner has assessed the risks associated with the operations supported by the EFB functions.
  • The operator/owner has established requirements for redundancy of the information contained in and displayed by the EFB functions.
  • The operator/owner has established and documented procedures for the management of the EFB functions including any databases it may use.
  • The operator/owner has established and documented the procedures for the use of, and training requirements for, the EFB functions.

Prior to completing the application form and ORA, it is recommended that Registry Publication 35 Application for Approval and Safe Operational Use of EFB is read by the applicant.

Subsequently an application for the approval of an EFB system should be submitted for each registered aircraft by the Operator/Flight Operations Representative (FOR) on Form 91 “Application for Approval of an EFB System” which includes the minimum Operational Risk Assessment (ORA) requirement acceptable to the Registry.

The ORA should be completed after the EFB system has been assessed by the EFB Administrator against the standards and guidance in this document.

As part of the ORA, the operator must consider the risks associated with a lithium battery fire and the effects of a rapid decompression.

The following information is available to assist the EFB Administrator/Operator.

Lithium battery fire and THERMAL RUNAWAY

There are videos and additional information available online which will provide support and guidance concerning the potential threat of the lithium batteries within an EFB (or PED) overheating, and the action required to manage a thermal runaway.

Some examples can be found below:

FAA video - Laptop battery fires 

FAA SAFO - Fighting Fires Caused By Lithium Type Batteries in PED

UK CAA video - Lithium batteries:guidance for crew

Transport Canada - Procedures for Fighting Fires Caused by Lithium Type Batteries in PEDs

RAPID DECOMPRESSION TESTS

Jeppesen have conducted rapid decompression tests on Apple iPad products which can be found on their website.

 

An EFB is defined as:

“An electronic information system, comprised of equipment and applications for flight crew, which allows for storing, updating, displaying and processing of EFB functions to support flight operations or duties”.

Note: Isle of Man Aircraft Registry policy is that Portable Electronic Devices (PEDs) that display Type A or B software applications are considered to be EFBs.
