Okay so what happens when several aircraft start squaking 7700. There were alot of a/c needing avoidance at the same time.
Agree on the TRUCE, went on one a few years back at the new prestwck centre before it opened. Very informative for both us and the new contollers. Unfortunately weather never came up. No of the aircrew or ATC bods thought to think of it. (big D'oh moment on my front)
