Pretty much as per the last (nforster) reply, within 50 yds of a road is a no no.
As for the "vicinity of an aircraft" bit, our Firearms Licensing think that relates to not being able to use a firearm within 2 miles of an airport, and pretty sure this would not constitute an airport.
A visit to the local nick should enable you to get contact details for the local firearms licensing bod, and a word in his ear may be all it takes.
The C.A.A. may be better placed to comment on the "vicinity of an aircraft"
