NAS rears its head again

[peuce]

mjbow2,

The biggest issue I have with enroute Class C over D Howabout is that if the risk of collision at Broome is such that Class D is justified, how can a higher classification of risk mitigation (Class C) be justified in the areas further away from the airport where the risk of collision actually drops significantly?

I re-read your post and you, in fact, did state your objection to Class C ... above.

My answer ...

1. the only reason we are having ANY controlled airspace further out is because CASA/OAR said we will. Can't say I've seen any justification either.
2. So, if we are having a Controlled Airspace link, then, presumably, it has to be safer than what we have ... Class G(F) with a 30nm MBZ.
3. Is Class E safer than that? No, as IFRs will be required to descend down through unknown VFR aircraft.
4. Is Class C safer than the status quo? Yes, positive separation between all aircraft
5. ATC have stated that they can provide Class C for the same cost as Class E

Seems quite logical to me
