Under a RAS in class G airspace from a controllers point of view, the fact that you are VFR is of little difference if say the commercial aircraft gets a TCAS climb. They have then failed to provide a RAS and the paperwork involved from the pilot and controller when a TCAS climb is initiated just causes more headaches.
So in order to avoid
your headache, you're passing the problem to Single Spey.
It's not the role of ATC in class G to ensure that TCAS equipped aircraft avoid RAs. It's similarly impossible to guarantee standard separation from other aircraft in class G, and the loss of standard separation under a RAS is not a "failure to provide" the RAS. Such a guarantee is not possible in the absence of an air traffic control service.
If your airport wants to provide greater protection for commercial users of that airport than is provided for in class G airspace, there is a well defined procedure for an application for controlled airspace which means that due process ensures the cost-benefit for all airspace users is considered.
