Well the Swiss use it heavily.
Mostly Marseille are the least likely to use it. Somedays it is not used at all, as I said often when the frequency is a little overloaded and it seems it would help the controller. I was just wondering if some controllers prefer not to use it or of there is a reluctance to use it as it might be seen as a step towards automating your job away?
From a pilots perspective when it works it is fantastic and cuts down the chances of an incorrect read back almost completely and helps prevent loss of comms. It's just a bit frustrating that their seems to be a reluctance to use it in certain sectors.
