CAA AFIS VFR Circuit

Explanation   Exchange
On the first call use both your full callsign and that of the station being addressed. If you have more than one apron, giving your position will help the radio operator identify your location.
“Duxford information, G-VACS, Optional (Radio check 122.080), PA28 on the eastern apron, request taxi information for circuits.”
The AFIS will give you the relevant aerodrome information.  
“G-VACS Duxford information. Taxi holding point E runway in use 24L, left-hand circuit, QFE 1024.
Information such as runway in use, circuit direction and QFE/QNH require read-back.
“Taxi holding point echo. Runway in use 24L, left-hand circuit, QFE 1024, GCS.”
Once at the hold and any necessary checks complete, report “ready for departure”. Note that it is not correct to report “ready for take-off”.
“G-CS holding at Echo, ready for departure.”
The phrase “take-off at your discretion” indicates the point at which the FISO is no longer giving you instructions. You are responsible for determining whether it is safe to take off. You should carefully check that the approach and runway are clear before entering.  
“G-CS Roger, no reported traffic, surface wind 260º/14 kts, take-off at your discretion.”
The term ‘take-off’ should only be used to announce that you are about to take off (in an AGCS or AFIS environment) or read back a take-off clearance from an aerodrome controller.
“Taking off runway 24, G-CS.”
Once established in the circuit, make standard position calls. Adding your intention (for example touch-and-go or landing) to the downwind call will assist the situational awareness of others, particularly in a busy circuit.  
“Downwind 24 touch and go G-CS /// When on final report final”
The term “land at your discretion” is used by AFISOs to aircraft on final. It emphasises that it is the pilot’s decision whether to land or not. It is not a landing clearance as you would receive from an aerodrome controller. You should ensure the runway is clear before landing.
“GC-S Roger, land at your discretion, wind 280º/9 kts.
Respond
“G-CS Roger”
In the UK, AFISOs issue taxi instructions to aircraft on the ground.  
“G-CS taxi to the end of the runway, vacate at Delta and then to the western apron.”
Respond
“Vacate at Delta and taxi to the western apron, G-CS”
If necessary, confirm the correct parking location.
“G-CS, request parking.”
   
“G-CS, park between the brown PA28 and the yellow Super Cub.”
 
“Roger, between the brown PA28 and the yellow Super Cub, G-CS .”
