Eagle
If as EESDL says it's unlicensed what safety procedures are in place for "Hawker" presumably jets. Is there any form of ATC, does it have an ATZ, is the airspace Class G etc.
Not sure but is it "legal" to operate into unlicensed airfields with jets. Maybe depends on type of flight. Don't know all the details of Leeds East but sounds a bit risky if there's a lack of procedures with Sherburn nearby.
If in doubt may be be best to use somewhere nearby where more established published procedures exist.
