Gonzo -
Quite right, though I was trying to get across the point that the digits 3-6-0- were the proper way to give the heading instruction!
HD,
I have use 90 degrees or more several times when giving avoiding action. Having worked in the military before NATS, I'm not shy in giving AA, though haven't had to do it much since I joined NATS (before people decry my controlling!).
When avoiding action is given, I always teach that finesse goes out of the window. If it has gotten to the stage of needing avoiding action, then no point pratting about giving a heading you think willl achieve 3/5 miles (whatever your minima is), grab a good handful then when you are sure it is sorted, go back and tidy up.
Admittedly more pertinent when controlling fast pointy things that have a tendency to suddenly appear...
