of portable EFBs in an operator’s MEL, but it is a means of controlling any inoperative EFB equipment. Other means may also be agreed with the competent authority. Any EFB function which operates normally may be used. Issue No: MMEL/2

of portable EFBs in an operator’s MEL, but it is a means of controlling any inoperative EFB equipment. Other means may also be agreed with the competent authority. Any EFB function which operates normally may be used. Issue No: MMEL/2
