Sounds like a certain Highland Airport.
You don't have to do anything Lxxxx say you have to do while operating under a FIS. They can't give you any clearances vectored, not above, not below (which really is taking the piss with VFR traffic).
They can request that you tell them your maximum operating level or that you inform them before changing level but thats it.
To be honest its pretty dangerous operating under the inbound AR at a level that they are happy with for seperation from the inbound IFR traffic. You have to be sub 500ft agl over a featureless peat bog for 3-4 miles with no chance if you donk goes. And your right in the slot for coming head to head with a tornado who is trying to avoid speaking to them and sneaking round the back to get to the bombing range.
Next question is why are they seperating VFR traffic from IFR in class G anyway? As soon as you are QSY to the twr you won't be seperated from them and you won't be seperated at the weekend.
And in answer to your question the pilots who operate in that area regularly have there heads out the window as much as possible in VMC. And it is nearly always safer to do a visual app than an instrument where you won't have any protection at all. one pair of eyes will need to be inside flying the procedure instead of two sets outside flying the approach and watching for traffic.
I heard rumours there is controlled air space on the cards with a civi controller. The seperation instructions will change to normal which civi pilots know and understand and which comply with normal rules of the air and air space classifications.
