A320 Anti-Ice protection
Hi everyone,
Just wondering under what conditions pilots and/or Airbus require (who hopefully fly the bus for a living) regarding the operation of the anti-ice system for both engines and the wings. For example on Climbout if the temperature goes below +8 passing 14,000ft would you switch on the engine anti-ice? and for example at +2 passing 16,000ft would you then also switch-on wing anti-ice? Or preferably what temperature dictates the need for anti-ice protection and at what altitude would you then switch them off? I'm interested in both climb and descent aspects, as well as during takeoff and landing, as I understand sometimes OAT dictates the need for ignition on older Airbus A320 family aircraft?

Icing conditions exist when the OAT (on ground and for takeoff), or when the TAT (in flight) is at or below 10 °C, and visible moisture in any form is present (such as clouds, fog with visibility of one mile or less, rain, snow, sleet or ice crystals).
Icing conditions also exist when the OAT on the ground and for takeoff is at or below 10 °C when operating on ramps, taxiways, or runways where surface snow, standing water or slush may be ingested by the engines or freeze on engines, nacelles or engine sensor probes.
FLIGHT IN ICING CONDITIONS
Engine anti-ice
ENGINE ANTI ICE must be ON during all ground and flight operations, when icing conditions exist, or are anticipated, except during climb and cruise when the SAT is below -40 °C.
ENGINE ANTI ICE must be ON before and during a descent in icing conditions, even if the SAT is below -40 °C.
Wing anti-ice
WING ANTI ICE may either be used to prevent ice formation, or to remove ice accumulation from the wing leading edges.
WING ANTI ICE should be selected ON, whenever there is an indication that airframe icing exists. This can be evidenced by ice accumulation on the visual ice indicator (located between the two cockpit windshields), or on the windshield wipers.
And this is exactly what we do, simples!! Airbus FCOM
