I was delayed 1 hour out of EDI today due to ice that built up on the jet fan blades during the inbound descent through freezing fog.

(We then had another 3 hours waiting for a slot due to fog at LHR - but that isn't the point of the post).

If the plane can pick up ice on the fan blades during descent throught freezing fog - obviously they can sort it on the ground. But what happens when we take off through the same freezing fog? Do the fan blades pick up ice - or is it that they spin faster on take off.

It took them 20 miutes to de-ice the engines after the landing - why isn't it a problem on take off?
