Obeying requests when on a FIS
I spend quite a lot of my time flying under a FIS from a military LARS unit. From time to time we get commercial IFRs descending over the top of us, both of us in Class G, with the IFR generally under a RAS. When that happens some controllers ask us to operate "not above x thousand" so they can descend the IFR to x + 1. I always accede to those requests but if I was on the flightdeck of that airliner I think I might have a slight doubt about the dependability of the separation, given that (a) I am still under a FIS, (b) I have no transponder, (c) I have not been radar-identified, (d) I am in an area which they frequently refer to as "an area of poor radar performance" and (e) I am under no obligation to stick to whatever I might have said I would do since I am operating VFR in Class G under a FIS.
Comments anyone?
