Having been in general aviation for a relatively small amount of time compared to most of you guys (12 years), I've noticed most of us have used the 'click' on more than one occation to acknowledge a transmission of information in certain situations. Me included. Although unofficially used it is in most pilots subconcious. I agree the controller should maybe review his safty procedures to eleviate undue stress on an already overloaded pilot but unless more is said about the correct use of the 'speachless' code by our instructors I doubt any of us will realy remember CAP412 for very long.
How many of you even have an up to date copy of CAP 412 any way!?
