Uncontrolled Airways
I just made a trip DKR to JNB on the offshore airways. Are these treated a uncontrolled or advisory airspace? We did the usual position reports, but asked for and received a clearance to climb FL 410 to FL 450, as the captain asked for a clearance and would not climb without clearance. I felt it was Class G or F (cannot remember exact position) and a clearance was not required, only the TIBA broadcast and the level maintaining during the next position report.
