Frequently Asked Questions - Electronic Flight Bags (EFB)
- What is the minimum size for an EFB?
EFBs need to be able to display information in a manner comparable to the paper aeronautical charts and data they replace. They should have a minimum screen size of approximately 200mm measured diagonally across the active viewing area. A PDA can only be used for calculations.
A smartphone is not appropriate or acceptable as either a primary or backup device.
- What is the maximum size for an EFB?
There is currently no maximum size for an EFB.
- What approvals are required for the use of EFBs?
CASA does not approve EFB hardware. An approval will only be required if the device is attached (with a mount) to the aircraft structure.
- Does CASA validate the software on my EFB?
Operators that intend to use software applications for weight and balance will need to have it validated by a weight control authority (CAO100.7). Performance applications will need to be validated by a qualified person and evidence of the validation retained for CASA review if requested.
- What is the legal requirement for a backup to my EFB?
For AOC holders, a backup is mandatory. It is at the operator's discretion whether the backup is another EFB, or hardcopy charts, maps and documents. The requirements of CAR 233(1)(h) are clear in that the pilot must have the latest documents from an approved vendor readily accessible. It is the readily accessible requirement that prompts the need for backup and all pilots need to ensure how they meet that requirement in the event of a tablet malfunction.
An electronic device such as another tablet is an acceptable backup. Private pilots can use tablet devices as a primary means of in-flight documentation, as long as the documentation is from a source authorised under CASR Part 175 Aeronautical Information Management.
- Which products for EFBs are approved by CASA?
Refer to the CASR Part 175 Data service providers information page for a list of approved organisations and services. Data service providers include some organisations or individuals who previously held a CAR 233 (1)(h) approval, and were authorised to publish aeronautical data, information or charts that pilots could use as an alternative to the Integrated Aeronautical Information Package and aeronautical charts published by the AIS provider.
