Why should we pay the EU to let us fly our own planes? The EU also want to fly their planes to the UK, and most of the routes from continental Europe to the USA pass through British airspace. I would expect any nominal payments for these activities would cancel out, resulting in roughly zero net payment in either direction to allow the present situation to continue after Brexit: if there are any payments to be made, for all I know the EU will end up making a net payment to us?
You might want to try looking at a map. There is a lot more EU territory for British aircraft to over-fly en route to various destinations, than there if of the UK for EU aircraft to fly over en route to the US (or Canada, for that matter).
