I'm not quite sure whether the point here's valid or not. Most European controllers really insist the pilots to readback at least the freq given to avoid confusion or maybe for the pilots to not wrongly tuned to somewhere else...happens pretty too often nowdays. Some old cappy used to scream at me when I readback for unnecessary radio chatter it seemed and on the other hand I got screwed by the controller for not reading it back! Went through the jepps and got myself more confused by the way it was worded and sampled out. I'm just seeking the correct way of doing things and hope that someone could shed some light to me! I know it doesn't carry that much of an impact whether you do it or not....but what do they really want us to do???
