Land After....
Speaking as a controller, can pilots please tell me if you ever get any proper training as to what this procedure is and why/when you are likely to hear it. We are not "clearing you to land" as the runway is not clear, we are basically saying land at your discretion, it is down to YOU as to whether you wish to accept this. Readbacks from pilots seem to indicate that some are aware while others have not a clue. Speaking to pilot friends it seems that you can find yourself in the RHS of a 737 without ever having heard of it and consequently causing some confusion very short final one day.
