I've never quite got the hang of what I'm supposed to say at A/G fields - I use them so rarely and they all seem to be different.
The most recent one I took off from, they told me at the desk to book out on the radio. So I called
"xx radio, G-ABCD, taxi for VFR flight to yyyy, three on board"
roughly as I would at an ATC field and got
"G-ABCD, runway in use xx, QNH yyyy"
which worked fine.
If it works it works.
For those who might be students or have an interest our 'book out on the radio' (A/G) is;
"xx radio, G-ABCD request radio check and airfield information, flight to yyyy, 3 POB"
Reply would be - "G-ABCD, xx radio, readability X, runway in use XX right/left hand circuit, QNH xxxx"
The CAA approved RT examiner chap conducting my A/G exam suggested passing the surface wind information on initial contact in or outbound but I don't unless the wind is such that it might be of concern to the pilot.
