At many airfields (possibly most in regional areas), ATC isn't able to be contacted on the ground. So if this change goes ahead, on an IFR flight plan, we would have to stay below 1500ft until a clearance can be negotiated? If so that would rule out a lot of IMC departures such as calculating terrain clearance in the splay (from ERSA) etc. We would need to stay within the circling area, get a clearance, and then depart which i think would raise the risk factor quite a bit if cloud was below 1500ft? Or is there another option i am missing?
