Is an ASIC an automatic right to go airside or do you also need an operational need, eg. I parked my aircraft on the apron at Essendon, hence my right to be airside at that airport?
If you need to go (say for operational reasons) from First Ave. to Northern Ave., which is a bit of a lengthy walk, could you just "cut straight across" the free movement apron on foot if you have your ASIC on?
