To help find an acceptable interim mitigation for a proposed Wind Farm, LSA approached Osprey as recognised leaders in Wind Turbine Mitigation methods. As part of their remit Osprey reviewed the potential capabilities of the local radar as well as other mitigation technologies in relation to the anticipated turbine effects and our Operational Requirement. Based on their assessment of the available solutions, the local airspace environment and the demanding project timescales, the use of a Non Automatic Initiation Zone (NAIZ) was proposed.

Osprey subsequently developed the Radar Sensor Safety Case to include the NAIZ and supported LSA through the subsequent discussions with CAA SARG. As a result of these discussions the NAIZ was accepted into operational service prior to turbine operation.

The solution has subsequently worked well and has proven itself to be the right decision for the mitigation of the Wind Farm.

I would readily recommend Osprey to any ANSP seeking supportive and informed assistance in establishing mitigation of Wind Turbines on Approach Radars.
