Tanx for the answer.However my confusion arose from reading the FCTM and the limitation from vol.1.The FCTM states under a note in the climb,cruse...section "The EAI system should be turned on whenever icing conditions exist or are anticipated. Failure to follow the recommended anti ice procedures can result in engine stall, over temp or engine damage".And from the limitations page "Engine TAI must be on when icing conditions exist or are anticipated,
EXCEPT DURING CLIMB AND CRUISE below -40C SAT".
