Relaying COMMS

As with all initial calls, the first two things you state are the callsign you are addressing (so the other aircraft) and then your own callsign (so the aircraft knows who is speaking to it). Then you can pass the message: crucially, this must include who you are relaying for as you have no authority as an aircraft to direct traffic. There are several versions of this question on the bank, so you should pick the one that is the closest to this answer.
