Algol: I did not ask for the return to the older radars, what would be the point? You demonstrate that modern pilots would not be able to use it anyway.
If I am coming up on a large area of activity and need to find the best way through (and I don't have the luxury of a super-airliner like you obviously fly so cannot go over it) I could, using the old equipment, find the route I wanted. Since you don't know what I am talking about there is no point my explaining it to you as to how to go about this, but believe me it was possible.
Modern radar makes all those decisions for me and for a modern pilot that is fine and dandy. Quite often though, the modern radar is wrong.
