<<Only headings I give are based on radar. So what headings were you using old man?>>
Headings out of my head - I don't need a radar to determine which direction I want an aircraft to fly in an urgent situation. Example.. Northbound departure lifts off runway 27L as one goes-around on 27R. I instruct the departure to fly a heading to prevent it from turning towards the go-around and then get some vertical separation organised. That's NOT a "radar heading" - that's simply an instruction to a pilot to steer his aeroplane in a particular direction to prevent an incident. I used that technique all my working life - including at two units where there was no radar equipment! Also, as mentioned earlier, I used QGH procedures extensively at one unit where there was no radar and issued headings to aircraft all day long!!
Maybe controllers nowadays are not allowed to use initiative?
