Working Hard
Don't understand why Class G airspace will increaseas CAS decreases, perhaps you have more information.
I and many colleagues would welcome VFR calling ATC for a FIS while in Class E airspace as we could then identify the aircraft and then the conflict would not exist as the aircraft becomes known traffic. Unfortunately some VFR pilots think that ATC will restrict such aircraft and won't call us up on that basis or maybe are getting a service from the FIR in class E but would perhaps be better contacting the nearest airfield in order to get a better service. (No disrespect to the FIR guys at all)
