AIP only lists licensed aerodromes.
For others, you might strike lucky and find the local club has the required information on a webpage (for example
http://cfc.deltabbs.org/page3.html or
http://www.enstonemicrolights.co.uk/airfield%20map.htm); try the directory at
http://www.pilotfriend.com/links/fly...clubs/126.htm, otherwise you'll just have to spend £20 on a copy of Pooleys like the rest of us.
