As reported elsewhere, HIAL are considering the introduction of radar into INV.
The trafffic levels over the last five years have increased significantly, and the introduction of INV radar would be most welcome. The present arrangement of Lossie radar providing a quasi approach function, although welcome in class G airspace, can lack from expedition when more than two aircraft are in the system at once.
There seems to be a reluctance by some to use radar headings to the best advantage, and prefer to observe the pass take place before climbing or descending the traffic. Perhaps the SOPs prevents this on some routes?
