Not all Class G, you may, depending on level, have to cross the new Class E airways to the west of TRN and GOW that were established at the back end of last year when Advisory Routes were ditched.
You can do this VFR of course, but the controllers at PC very much like you to give us a call because we can then issue a discrete SSR code and our rules for avoiding you with Airways traffic become MUCH easier
That's great info FC. Will bear that in mind. I assume you are talking about clyde-fyner-bruce at FL55?
