Williamtown VFR Flight Planning

[CaptainMidnight]

You'd be sequenced or processed by ATC based on when you call up seeking clearance, not based on times in your flight plan.

From my understanding of things, a flight plan in the system with a half reasonable ETD from the last point of departure will assist.

Whether or not the ATC flight data processor puts your flight plan into a "pre-active" alert state to the relevant sector based on the ETD I don't know, but in any case having the flight plan in the system means it will at least be there able to be called up by the ATC, instead of them having to drop everything else and obtain and key in the details (feed the beast).
