Morse Code by Flashing Morse Code by Flashing LightLight
Non Directional Flashing is Morse Code sent from the mast head light, and is used when you want to send a message to more than one ship.
Directional Flashing is Morse Code sent from a and is directed at one ship.
FRX (Flash Receiving Exercises) and FTX (Flash Transmitting Exercises) use Tactical Voice Procedure and Tactical (Alpha Numeric) Call signs.
Audible Morse is no longer used in the Royal Navy, but a good Tactical Communicator will be able to transmit and receive both visual and audible Morse Code.

Saying the Delayed Saying the Delayed Executive MethodExecutive Method
If you wanted to make all ships turn If you wanted to make all ships turn 9090° to starboard, you would SAY ° to starboard, you would SAY over the radio the following:over the radio the following:
Z0, this is A1, execute to follow, turn starboard 9, B2 over.
Call sign for all ships
Your CS
Means “await another message before executing it”
The order
Means you await a receipt
Z0, this is A1, standby.................EXECUTE, C3 over.
Means “Carry out the order......now”
So the radio transmission So the radio transmission would go:would go:
• Z0, this is A1, execute to follow, turn starboard 9, B2 over.

As you can see, it is all done in one message. It is vitally important you repeat the order, so everybody hears it. If by the time you have reached “standby” and your Captain is not ready to action the order, you continue saying “standby”. Standby....standby....standby......Execute. Everybody should receipt the order afterwards.
