I can see why the use of degrees is used after headings with a zero to stop confusion with levels in Controlled Airspace,but up here there is another problem.We work a lot in class F and G airspace where Quadrantal levels are used all the time.So do we not use degrees after all headings;for example ''Turn right heading 125, climb flight level 115''.Same problem.
Can't get a straight answer on that.
