I'm struggling to understand the intent of establishing a control area "with a base which is as low as possible". Isn't 1' AGL 'possible'? Anyone with expertise care to expand?
taking a guess here, but I think you’ll find the SSR coverage is a bit dodgy down low, and the ADS-B isn’t enough to enable a surveillance control service in class C. Therefore what’s being suggested is to extend CTA to as long as the surveillance will allow, then the class D will take over.
