EFBs are divided into three categories:
Class 1. Completely portable, consumer off-the-shelf electronic equipment to be used by flight crew and never connected in any way to any aircraft system. Unmodified cockpit stowage locations are used when the device, or any associated peripherals are not in use. A communications interface, for example GSM telephone connection or built-in phone card, may be part of such equipment. In such cases, acceptable precautions of inadvertent transmissions will be required.
Class 2. Electronic equipment for which connection to the aircraft and its systems is both possible and permitted. Formal aircraft modifications will be associated with Class 2 equipment.
Class 3. Electronic equipment supplied, supported and permanently installed on the aircraft by the original manufacturer or similar approved organisation. Normal aircraft certification processes are expected to cover Class 3 devices. No additional equipment approval by the CAA is expected to be required.
Prior to the approval for additional electronic devices to form part of an AOC operation, it will be necessary to demonstrate that, when fitted to an aircraft, no additional hazards will result.
Approval should be sought from the assigned Flight Operations Inspector.
Approval should be sought in accordance with existing Modification approval processes.
It should be noted that any approval issued does not verify acceptance by the CAA of the EFB hardware, operating systems or database information. Approval confirms only that the system is capable of performing its intended functions to an acceptable standard.
