Imagine a world........ok, imagine an approach control unit without any strips whatsoever. What! Preposterous! Impossible! Yet many Canadian, US, and other approach units function perfectly well without strips. Strips date back from non digitized radar, when indeed they served a useful function.
It was brutal, when arriving in DXB, to have to go back to writing on paper strips. A complete waste of time and energy, according to all who have lived in strip-less nirvana!
