Acknowledge transmission

[Guest burbles1]

Have been wondering, when you acknowledge receipt of a transmission from another a/c, what the difference is between stating "Copy that" and just a double-click. When do you use which transmission? These transmissions aren't written in any standard phraseology but they are more commonplace than what you'll find in any study book. Is it a case of "know the phraseology for the exam" then do it differently in the real world?

If you use standard phraseologies as per AIP misunderstandings will be reduced.

The double click is not a valid form of acknowledgement under any circumstances. They can be just airwave "noise" in which case the other party has no way of knowing if they were understood or even heard. After all, the radio is used for communication and communication with radio consists of two things...speaking(keep it simple and clear) and listening. The double click has been in existence all my flying life and I don't expect it will die out at any time, but put simply its not good enough.

in the broad sence, if the call is a genuine phrase or instruction, then acknowledge with your call sign, if its just in response to general chat or question, then just a double click

 

eg, ABC traffic is a cessna in your 2 oclock at 2000 ft, you would reply with your callsign.

 

or if your turning final, and an aircraft on the ground asks if you dont mind if he crosses the runway, then just a double click

".... and an aircraft on the ground asks if you dont mind if he crosses the runway, then just a double click"

 

The guy on the ground has no idea if he was heard or not and should he or should he not cross in the limited time available. The crossing pilot must have had some uneasiness about the closeness of the situation to even make the call.

 

I'll stand by the "just not good enough" statement.

 

Cheers

Ok ill re-word the example, you are in the circuit, and someone you know well calls they are departing the circuit for god knows where, and he says to you, have a great day cath ya later, then a double click is fine to acknowledge you have heard his/her sentiments......

 

that better..:big_grin:
