Narrative:

In 2019 52% of TCAS RA (traffic collision avoidance system resolution advisory) events occurred within 25 miles of the deschutes [dsd] VOR. Based on a total of 260;000 square miles of seattle air route traffic control centers airspace. (According to data presented at bend municipal airport).at a meeting; ATC expressed that they initiated the meeting as they have 'genuine concern over the unstructured air traffic' in central oregon. They stated 'we often have no idea what they are doing; no communication and no structure.'commercial pilots were in attendance from: several airlines as they have a genuine concern with the number of TCAS events and aborted approaches due the unstructured volume.ATC recommended 'avoid the dsd VOR if at all possible;' yet despite all of the above; the flight schools continue to circle the dsd VOR non- stop on a daily basis.yes; the flight schools have a legal right to use the VOR. But at what cost? Does there need to be a catastrophic event?the FAA tag line at the end of every letter to concerned citizens: 'the FAA is continuing to manage the NAS in a safe and efficient manner while continuing to explore measures to reduce noise from aircraft in the future.' is this a true goal or just a tag line?many of us use the commercial carrier on a regular basis. We are very fortunate to have the fabulous commercial service out of rdm. But we are the same people; (along with our families; friends and colleagues) who are onboard the commercial carriers as these repeated TCAS events are occurring. The commercial traffic is not the issue.the FAA needs to move the training traffic off of the dsd VOR. We all deserve safe skies; not continuous near misses.

Title: Reporter stated heavy training traffic over DSD VOR often results in TCAS RAs for air carrier aircraft. This is reportedly a known issue; but there is no solution yet.
