Self assessment maps show that the site;
• Appears to be outwith a Primary Surveillance Radar (PSR) zone
• is in an area of concern with MOD/MET office radar for larger wind farms
• is in an area with no military flying concerns
• appears to fall within a Civil Aviation Aerodrome or Consultation Zone
Maps are also available through NATS EN-Route Plc (NERL), which are designed to aid developers in
understanding where interference with NERL infrastructure is likely. The maps provide guidance and do
not represent no-go areas nor do they represent an exhaustive list of areas which will be affected.
The proposed turbine position is within 15 nautical miles of a Secondary Surveillance Radar (SSR) and it
is within 10km of a Navigation Aids (NAV) consultation zones. Air Traffic Services would carry out a full
in-depth assessment, upon receiving a turbine application. It is outwith10km from an Air Ground Air
(AGA) zone.
In addition, the proposed site with a 45.9m to tip wind turbine on it is not within 10km of an Air-Ground-Air
or Navigation Aid site or within the detection zone of NERL’s Primary Surveillance Radar.
Five civil aviation primary surveillance radar (PSR) positions were identified as listed in Table 3 below.
On examining the distance from the identified PSRs, it was established that it is unlikely that any, other
than Glasgow PSRs, would be affected. Therefore, radar lines-of-site were analysed to identify the
likelihood of the Glasgow’s radar being affected by the development. From this it is considered possible
that Glasgow PSR could be affected as it is visible. However, it should be noted that being visible to radar
does not always mean that there will be a sustained objection as buildings or trees may shield the
proposed development, the radar operator may have no operational concerns and the turbine may be a
significant distance from the radar so as not to cause clutter. The lines-of- sight for the PSRs are shown
in Appendix I.
In addition to the above airport PSRs, Aberdeen, Wick, Inverness and Campbeltown airports were also
investigated. However, owing to all being over 50km from the proposed turbine site, it was assumed they
will be unaffected by the proposed development.
