I have noticed on a couple of airfield a cartwheel shaped concrete area (or orange slice if you like) which I assume to be compass related. The two that spring to mind are Weston-on-the-Green and Hullavington.
Can anyone confirm their purpose, why that design and when were they laid down? I assume postwar.
Any other airfields have them. My main interest is dating evidence.

By chance, as I was looking (in Google Earth) for the lube oil depot at Barton I spotted a similar 'wheel' on Barton airfield however it does not show on Flash Earth
PNK: Do you have a picture of this feature> Many pre-war airfields had a circular concrete marking known as the "Landing Circle". This was mounted flush with the surface and denoted the centre of the landing ground. I think it features on the Record Site Plan of a number of RAF expansion-period airfields (before runways were laid of course) and I remember the one at Grimsby Waltham was still visible in an aerial photo taken as late as 1972.
'Cartwheels on Airfields' You're not allowed to perform them on an airfield!
I'm not sure what you are reffering to exactly, but are these airfields all grass? If so and there is one concrete circular pad then it probably is the compass bay.
St Athan has a few concrete circles and the only explanation I've heard for them is that they were barrage balloon mooring points, but I have never seen official reference to them or their use here.
The circles at St Athan, could they be hardstands? A lot of early war grass airfields had the odd hardstand in the middle of grass before proper peri tracks were the norm. Some would have had a small vehicle track whilst other might have a lead in handle, again not attached to any peri track but may somtimes be attached to roads. Just a thought.

hi all
the cartwheels were for parachute training
a barrage balloon with a large basket for something like 6 people was moored in the middle
the cartwheel was so that in any wind direction they could still train
