That approach starts at SBKWB on the edge of the 2500 step. You have to be at 2500 at that point. Which means you will have left class C on descent already several minutes earlier. It seems to be what Sydney wants for all IFR aircraft going into Bankstown. In the event you ask to stay in class C on a VMC day you can easily find yourself close to Bankstown and too high to get down easily. So most people seem to descend below the steps.Yes the standby Ai played up. But I had an electric turn coordinator so all quite legal for a private flight.
@@emz2651 I see. But the 25Nm MSA in that sector is 3700'. Can't you just descend leaving controlled airspace at 25NM? But I understand if that what's sydney wants to get out of the way of RPT IFR traffic. I'm guessing they descended you one day, and that's how you found out? Sorry, not trying to debate this, just wondering about approaches into Bankstown.
You could do that. If you are tracking from somewhere over the blue mountains direct to BKSWB, you can initially use the Richmond 25MSA of 5000 to start descending, then use the BK 25MSA of 3700 as you suggest.Note there is a 15nm MSA of 2500 at Bankstown. Not 10, 15. Why do they have that? I think to deal with exactly this situation. It helps you comply with the SYD 20DME step.Note also that when descending along route Y20 towards BK, when you need to get visual but don't actually need the RNAV approach, waypoint ANPEN picks up the 25NM point and from GOMUB you can go to 2300, and 2000 after NOLEM. They have designed that to allow IFR flights to descend OCTA and get in most days (or I assume that is the intention).
