EFB power supply

[jaja]

A321 & A330

What are the requirements for EFB powersupply ?

Do we need 2 Independent powersources ?

Is there special requirements for ETOPS operation with the A330 regarding the above ?

Please make reference to appropriate EASA & FAA documents

In general your CAA will be asking to see Operational Risk Analysis as per the document suggested above. If your intentions are reasonable there should be no issues writing up one that will be acceptable.

FWIW.Capt and FO EFB have separate CBs. Independent power supplies.
