ARFOR,
As for YBPN I wasn't talking about terrain avoidance - see my last post. Dick's the one that argues that ICAO states that the best mitigator against CFITs is ATC with Radar.
Now let me get this straight.
On one hand you argue for using C rather than E because the cost is minimal.
Yet you don't want to use E rather than G because??? OK there are display, monitoring and staffing issues. In AUS G you (ie ATC) have to assess whether to pass aircraft as traffic - I assume you use the same standards you would use for separation in Class C. Yes it would add some workload to actually separate the aircraft, and it would certainly add delays.
But then what would I know - with over a couple of thousand hours of charter logged I still don't have either an instrument or twin rating.
