Umm..isn't Moorabbin Class D..? There's no doubt its a lot harder to get a clearance through CTA travelling Moorabbin to Nth West and return. Despite following recommended procedures in ERSA. Been stuffed around too many times to be bothered now. The time (and $) wasted either holding OCTA or being diverted around control steps, not to mention the aggravation just isn't worth it. Shouldn't be the case I know, but I've pretty much given up trying now and just plan the trip OCTA. Back when I did my PPL, as long as you could demonstrate you could handle an entry & departure from Essendon, you were signed off as good to go in CTA. Nothings changed with that as far as I'm aware.
