Bell Ringer . In the UK in the UK you will only have ATC coverage from a major airport and then , unless requested , you will sign off as soon as outside their area . I dont think we really want to be in a position where we have to be talking to ATC in class G airspace . We are lucky here to have relatively free airspace and can fly over most of our country without speaking to anyone but that comes at a price and maybe that price is that we monitor ourselves with the tech available . I will now certainly be adding TCAS to my aircraft because like Crab , i have had too many aircraft converge on me and get scarily close.
but it only works if ALL aircraft must have a transponder .
