ulm,
We did have an airspace model that was going to be suitable for all and it was called Llamp. Pity some thought otherwise!
Spodman,
You are almost correct. ASA will only be able to "see" aircraft that are line of site to a ground station (radar). But the ground station does not "retransmit" this info back up to aircraft.
For aircraft that are equiped with recieving eqipment, they will able to "see" other aircraft irrespective of ground base coverage.
If one aircraft cannot "see" another one it is too far away ie, over the horizon from each other.
As for the flip card
Interesting at the FLOT the part pursuant to NAS has been with held until openmike has finalised the NAS, then CASA will re-issue the part and it will be "Compliant".
Good to see CASA rolling over. The only person who has the power to stop NAS it the Director (he can always leave and give a very public reason for doing so) and he is doing his usual. The Minister can only "Direct" the regulator, not the people.
