I am just pointing out a few inconsistancies in the system.
Mount Isa, Cloncurry and several other western Queensland airstrips have signage that conflicts with the conditions of use that are imposed on us. I can also name a couple in SA that have the same situation.
For example, Mount Isa has a notice on gate stating that the ASIC must be displayed at all times but the tarmac has 'sterile area' delimitation markings on the tarmac and therefore if you follow the instructions and use the ASIC in the GA area you are breaching the conditions of use that are set out by the governing body as it is being used in a non-strile area.
Damned if you do and damned if you dont. You can loose your ASIC card for following a 'lawfall instruction (the sign)'.
The concept of the ASIC card is commendable but the execution leaves a lot to be desired.
The system needs to be broken down in layers and real secutity ratings applied. Adeilade seperates all incoming regional flights from the big boys. Differant levels for differant situations.
RPT operations should occur in a seperate 'sterile' areas away from non-RPT -GA operations, RED ASIC card for the RPT area (when in operation) and a Green card / AVID / photo licence for the GA area. There is no need to be hanging around the 737 when I am meant to be playing with my own aircraft.
Layed security is the only workable option but examples of situations such as declaring VRD (dirt strip, 400k SW of katherine) only shows the stupidity of the system as the largest aircraft that can use it is a small twin. I wouldn't park a 210 under the wing of a 747. Common sense.
Remember that a person only needs to be under the direct supervision of a ASIC holder to be in the area. It is technically possible that you can fly in and out of major airports by prearranging the 'supervision'. I've been laughed at by a couple of refuelers when I called them to arrange fuel access but it complies with the sprit of the system and the rules.
I have worked under those 'supervision' circumstances in the international terminal area at Melbourne airport.
