Going from what you've posted above perhaps you had better give all your clearances out in duplicate.Or triplicate.
No ....and frankly that is puerile. We are instucted to consider the taxi phase as a "crucial moment"during the flight.You will be,I am sure ,busy. I may also be busy.The guy on final approach for the runway may be "busy".Which is preferable? The clearance unambiguously given(even if it means twice)or I trust to your,mine and the guy at 125 knots infallibility and let things go?.
As far as duplication goes the ENTIRE system is built upon checks and balances. I clear you ....you read it back....you get take off clearance you read it back...the first call to radar you offer your cleared level radar will confirm it.The name of the game is safety.If you have a particular dislike ,well I am sorry .Until there is a better way to do it you will have to bite the bullet.
I agree with you regarding poor r/t however I am not looking at it from that point of view but from the SAFETY point of view.Another thread is dealing with "wheres my traffic" THAT is a waste of R/T time and an interupption to my thought processes,but I am sure you would never try to second guess the guy with the radar!
