Which Limit?
I've wondered about this myself. The Jepps state that IFR aircraft in Class C airspace have no speed limit.. except SY, BN, ML, GC. I don't fly STAR's or SID's but believe the limit applies to them. To me the speed limit is the exception rather than the rule. Anyone have any other reference than Jepp- ATC- AU 511?
In any case Im limited by the AFM to 250kts below A080 for bird strike and agree with the previous words of caution...
