I´m in Spain until monday evening and i haven´t finished the radar detection circles or the implementetation of the other airport maps yet, so i will post a link for an updated version around wendnesday i guess. thx for all your comments.
I´m not so sure about the AWACS. I think its a lot of work to implement an altitude map to figure out if some plane is hidden. What i could try to do is fake the whole thing by simply defining mountain areas and hide planes as long as they are, say below 100 metres of altitude ? But that´s also quite a lot of work, so it´s more of a long term goal.
