Today, 10th November 2016, there are some changes going live to Australian ARFOR. The winds aloft in the ARFOR now only extends to 10,000ft (where it was 20,000ft previously). Additionally, ARFORs will not be amended, but AIRMETs will be issued for significant weather changes.
AvPlan EFB 7.2 automatically uses grid winds above 10,000ft.
