requirements" include weight and balance calculations, or performance calculations required by the aircraft's approved flight manual.
(c) functionality level 3 means that the EFB has:
 (i) the functionality of functionality levels 1 and 2; and
 (ii) 1 or more software applications that permit one-way only acceptance of data directly from the aircraft systems for use by the flight crew to satisfy operational requirements; and
 (iii) data connectivity with the avionics systems of the aircraft:
(A) on a one-way, read-only basis; or
(B) to receive or transmit information for aircraft administrative control processes only; and
Note   For example, the link may be via Wi-Fi and as a data link must have system security.
(d) functionality level 4 means that the EFB has:
 (i) the functionality of functionality levels 1, 2 and 3; and
 (ii) 1 or more software applications that permit acceptance of data directly from the aircraft systems for direct input to the aircraft's flight management system to satisfy operational requirements; and
 (iii) data connectivity with the avionics systems of the aircraft that:
(A) is secure; and
(B) does not have adverse effects on the avionic systems of the aircraft; and
(C) has High Intensity Radiated Fields and lightning protection; and
(D) is capable of being overridden by manual input in the event of an EFB malfunction or failure; and
(E) may receive or transmit information for aircraft administrative control processes.
Note   This bi-directional link may be via wireless connectivity, for example, Wi-Fi, and system security must prevent external interference.

2 Software application validation
       2.1This clause applies for a software application (SA) of the kind mentioned in subparagraph (b) (ii) of the definition of functionality level 2 in subclause 1.3 (including when functionality level 2 is adopted for functionality level 3 or functionality level 4).
       2.2Before first use of the SA, or after any updating of the SA, the AOC holder must:
(a) validate the output from the SA for the aircraft to ensure that it complies with the performance limitations set out in the AFM; and
(b) retain written evidence of the completion of this validation for the duration of the validation; and
(c) make the written evidence mentioned in paragraph (b) available to CASA on request.
       2.3If the SA is for use in weight and balance calculations for an aircraft, the suitability of the SA must be validated in writing by a weight control officer (within the meaning of Civil Aviation Order 100.7).

3 Permitted EFB
       3.1The AOC holder's operations manual (the operations manual) must clearly identify the EFB which the holder permits a flight crew member to use (a permitted EFB).
       3.2The identification of a permitted EFB in the operations manual must indicate its class and functionality
