Airbus use of engine anti-ice
After reading the Airbus FCTM section on ICE CRYSTALS and how they may have an adverse effect on the aircraft, I am surprised to see how there is no suggestion at all to use engine anti-ice to protect the engines when unable to avoid these conditions.
There are many documented cases in which aircraft engines have been affected and I would think using engine anti-ice would be a sensible thing to do even if the temperature is below the icing conditions range (10C to -40C in cruise).
In the FCOM under normal procedures, IN FLIGHT.. just below the note "In the climb or the cruise phase, when the SAT goes below -40C, the flight crew should turn off the engine anti-ice."
you can read.."If the flight Crew does not apply the recommended anti-ice procedures, engine stall, over-temperature, or engine damage occur."
Why is Airbus using SAT -40C as a limitation for the use of engine anti-ice in cruise regardless of flight conditions.
Any comments on this?
