Hmmm.
I don't think removing the Icon is a good idé.
There is, after all, a DR Plot, the accuracey of which is dependent on your QMOW.
When you, or more likely, your QM, get a Fix, that's when the Icon can be shifted to it's correct position.
As long as land is visible you get an Automatic Fix.
Warning: Returning to port in Heavy Fog, may not be a good idé.
