I am of an age when UK ATCO's had to hold procedural ratings at certain airports.
I had just validated my rating and the first bit of procedural control was an AAC Beaver looking to carry out a QGH to runway 07.
First and ONLY time I ever used it.
I am devastated if QSY has gone. It was always used as shorthand for getting the "early go" ..the phrase used was "after that one you can qsy ops..." i.e. leave this frequency ,go home.
