If you mean Rochester Airport, Paul, that's hardly a reasonable basis for comparison: it's a licensed aerodrome (i.e. licensed by the CAA for use by aircraft for the purpose of "public transport of passengers", and for flying training using larger or multi-engine aircraft), with protected airspace (Aerodrome Traffic Zone), runway lighting for night operations, and three flying schools, one with a substantial training fleet.
If you find yourself in the area, pay a visit to Clipstone Farm airstrip, near Denton: it's much closer to what's envisaged at Manor Farm, although with a small caravan park rather than glamping pods! Alternatively, try Hamilton Farm airstrip and caravan park, near Ashford. Both provide hangarage for a modest number of light aircraft, and accept a limited number of visiting aircraft by prior permission. I wonder how many people realise that there's an airstrip as close by as Ripple??
In answer to your earlier question, I live about 3 miles from the farm strip where my own light aircraft is based, together with 9 others. The owner permits the occasional visiting aircraft, but only following a mandatory telephone briefing that includes the need to avoid overflying specific noise-sensitive areas/properties. My own home, in a rural hamlet of fewer than 30 properties, is slap bang in the middle of the Local Training Area of two licensed aerodromes with several flying schools (including the one at which I am a part-time instructor), and is clearly also a turning point for (sometimes very!) low-level sorties by a variety of military aircraft; interestingly, few of my neighbours appear to notice this aeronautical activity! There are, however, two local sources of noise that are widely considered a nuisance: motorbikes speeding on a long, straight section of an A-road a mile away, and late-night music from a Wedding Venue in a nearby village.
Finally, I fear you misunderstand the purpose of "The Circuit"; please bear with me here! At an aerodrome with a full Air Traffic Control service, a pilot's approach, landing and departure will be directed by a Controller (ATCO), usually with the benefit of radar assistance; at other licensed aerodromes, an Aerodrome Flight Information Service Officer (AFISO) or an Air/Ground Radio Operator may provide the arriving pilot with information such as the runway currently in use, meteorological conditions and local traffic information of which they are aware, but the responsibility for the safe planning and execution of approach, landing and departure rests solely with the pilot; an unlicensed aerodrome may provide an Air/Ground Radio Service or no service at all: arriving and departing pilots may announce their intentions to other air traffic in the vicinity by means of blind radio calls on the "SafetyCom" channel, but this is not mandatory and, in any case, aircraft may operate "non-radio" in uncontrolled airspace. At the vast majority of aerodromes, therefore, the safe arrival of aircraft depends upon the discipline of "The Circuit".
The Circuit basically provides a predictable flight pattern that allows the pilot of an arriving aircraft to familiarise themself with the landing area and safely to integrate their arrival with others. Joining the circuit is an essential element of airmanship and, at a busy, uncontrolled aerodrome, is perhaps one of the most essential. The majority of uncontrolled aerodromes therefore promulgate joining instructions, together with a circuit pattern that avoids noise-sensitive areas, in order to ensure safe and disciplined approaches and landings.
The circuit also provides a pilot with the facility to maintain landing and takeoff skills by performing a few "touch and go" manoeuvres if necessary to satisfy currency requirements. At a training aerodrome, "flying circuits" may indeed constitute the majority of aircraft movements but, at a typical farm airstrip, circuit flying for its own sake is relatively uncommon: an experienced private pilot and aircraft owner is more likely to wish to fly off somewhere for lunch with family or friends than to fly repeatedly around Little Mongeham.
