I note a number of you have raised the issue of R/T and how some of you feel thats badly taught or you feel ill prepared.
Most ATC units will welcome a visit from PPLs and those learning to fly , if you are uncertain about arranging the visit yourself I am sure your flying club could probably arrange something for you.
To talk to ATC face to face may take away some of the fear of talking on the R/T. They may also be able to give you some guidance on various phrases you may feel uncomfortable with.
R/T to us is a second language we use it day in day out and are very comfortable with it , but we are very aware that when you do not use it very often it can be a struggle.
If in doubt ask , we only bite sometimes
