I was taught many years ago that an AIRFIELD is that part of an AERODROME on which aircraft manoeuvre. An AERODROME comprises the AIRFIELD, plus hangars, technical and administrative buildings, and an AIRPORT is an AERODROME which is open to public air traffic.
In Service parlance, a STATION includes an AIRFIELD, a TECHNICAL SITE and a DOMESTIC SITE.
