Ashcroft (EGCR) is an Unlicensed (not private) recognised Diversion Airfield
Current Issues: "securing the safety of ...aircraft and of persons and property carried therein, [and] for preventing aircraft endangering other persons and property"

Public Safety on public roads & houses.
Confirmation of correct AFM performance
Road Safety Update: A low boundary road overflight that occurred in mid 2013 was captured on CCTV and was considered a 'reportable event' (see definition below).
Concerns were raised on 30.07.2013 and CCTV evidence was provided on 30.12.2013
A forensic report of CCTV data shows that the aircraft crossed our public road well below 50% of a normal flight profile. Any deliberate low crossing of our road affecting public safety is not only unacceptable to Ashcroft but also to the general public
Additional concerns are that the aircraft may have flown below minimum "reference speed" of 60kt to achieve this unorthodox landing. The aircraft speed will be checked using CCTV data, by the same forensic lab, which established the aircraft's road crossing height.
The general public expect the authorities responsible for regulating aviation laws / risks to be seen to act in a transparent manner by endorsing their policies, laws and public statements. Waiting until something goes "seriously wrong" before corrective action is taken, seems to contradict the teachings of every Pilot in the UK ... and may be viewed as unacceptable by the general public ... if they believed that their lives were at risk, because standard policies and laws had not been observed.
In the unfortunate event of a fatality to any member of our general public by Group 'A' aircraft pilots NOT using "sensible performance planning" & NOT using "normal airmanship" then it is likely that there will be a Coroners Inquest assessing the reasons why this was allowed to happen ... despite multiple warnings given by the Airfield owners
To be clear, unless diverting into Ashcroft, we will pursue anyone assessed as jeopardising our public by not planning to cross our boundary road by 50ft or more.
Similarly, landing on Easterly Runways with this public road at the end also requires sensible performance planning (taking into account the 0.8% downslope on RW09)
SSL 07: 8(c) "You should always ensure that after applying all the relevant factors .... the Landing Distance Required (LDR) from a height of 50 feet does not exceed landing Distance Available"
In our experience, most pilots act in a responsible manner and adhere to the relevant CAA safety policy documents regarding aircraft performance and Rule 5
In view of events in 2013, Ashcroft would like to define a 'reportable event'
A pilot planning to use Ashcroft Airfield but not using "normal airmanship" and assessed as endangering the general public on the Airfield perimeter Road owned by Ashcroft.
A pilot of a Group 'A' aircraft not using sensible aircraft performance planning measures, liable to endanger the general public (or any passenger in that aircraft, that has not been made fully aware of the risks of departing from ANO Article 87)
Whatever the CAA's attitude is to 'proportionate risk assessment', we have been advised by an Aviation Lawyer, that we have certain "responsibilities" to try to offer some protection to those individuals, who are not fully aware of the risks associated with aviation activities.
Ashcroft Airfield welcomes Pilots with a sensible 'Community Aware' attitude
Since our road is used by the general public, appropriate aircraft performance calculations (iaw the most recent performance data) are legally required to clear this road by at least 50ft iaw ANO Rule 5(3.a) ... pertinent to Unlicensed Airfields
Rule 5 (3.a) Failure of a Power unit: "An aircraft shall not be flown below such height as would enable it to make an emergency landing without causing danger to persons or property on the surface in the event of a power unit failure"

CCTV data collected on 06 March recorded a 38 min inspection & 4 vehicles driving on our perimeter road between 13:33-14:05 (2 high-sided Vans, 1 Landrover & 1 Hatchback)
Recorded samples: (some days missed due to lens contamination & winds triggering false events)
02/04 03/04 04/04 05/04 07/04 09/04 (10/04+10/04) 11/04 16/04
CCTV cameras now re-positioned to collect data on our public highway from 0900-1800 between 02 Apr - 22 May in order to assess the risks to the general public, regarding low public highway overflights and over-run risks when landing on easterly Runways.
Bona fide samples of Road traffic between 09:18 and 17:29 on 10 April
CAA Safety Policy 7C (JAN 2013): Accidents such as failure to get airborne, collision with obstacles after take-off and over-run on landing occur frequently to light aeroplanes. Many have happened at short licensed runways, as well as strips, often when operating out of wind or where there was a slope. Poor surfaces, such as long or wet grass, mud or snow, were often contributory factors. Many, if not all, of these performance accidents could have been avoided if the pilots had been fully aware of the performance limitations of their aeroplanes.
CAA regulatory view of GA: "for securing the safety of air navigation and the safety of aircraft and of persons and property carried therein, [and] for preventing aircraft endangering other persons and property". The UK Rules of the Air Regulations are enabled under the ANO"
Caution: Regarding limitations of the "See-and-Avoid" Principle. Peripheral vision is reduced under conditions of high workload.
"A number of researchers have shown that peripheral stimuli are more difficult to detect when attention is focussed on a central task"
Safety Sense Leaflet 13: Collision Avoidance
"Another inherent eye problem is the narrow field of vision. Although our eyes accept light rays from an arc of nearly 200°, they are limited to a relatively narrow area (approximately 10–15°) in which they can actually focus on and classify an object. Although movement on the periphery can be perceived, we cannot identify what is happening there, and we tend not to believe what we see out of the corner of our eyes. This, aided by the brain, often leads to 'tunnel vision'.
"The pilot’s functional visual field contracts under conditions of stress or increased workload.
The resulting ‘tunnel vision’ reduces the chance that an approaching aircraft will be seen in peripheral vision"
