richardlittle,
I hope the above link works. Extend the runway centreline until it meets the Ifield/Charlwood Road and this is the spot I think you have in mind. It does indeed sit on a slight rise, looks over the field to the Lowfield Heath Road, you can see the aircraft on the runway and sits right under the final approach from the west. There is a small unpaved lay-by with some gaps cut in the hedgerow at roadside that helps the view. Not much shelter if the weather is off.
