Switch off engine anti-ice during de-icing?
Hi there!
As usual, apologies if this has been discussed earlier.
I have a question which came up recently.
Do you need to switch off the engine anti-ice during de-icing on the ground?
The Airbus 320 FCOM clearly states that you should prepare the aircraft for de-icing by closing the bleed valves, pushing the ditching button etc. All very good. But what about the engine anti-ice when you de-ice with the engines running in icing conditions? Should you switch those off also so as to prevent fluid ingestion in the cowl anti-ice system? Or do you leave it on to prevent ice buildup on the engine?
I can't find any reference to this..
