The President was here in NY last week.....same TFR bull as always, here's how it goes in NY.
There is a 30NM TFR set up around NYC, basically the 30NM mode C veil of Kennedy/La Guardia/Newark marks the area from the surface up to the heavens.
No aircraft may operate in this area without an assigned transponder code and all aircraft will be in contact with a tower or approach/center.
No flight training may be conducted within the zone, so aircraft originating from airports within the zone must travel outside to conduct training, no touch and goes allowed.
Leaving my airport VFR involves filing a DVFR flight plan (from the ground!! No filing in the air). I simply defined the route of flight as going to the nearest VOR outside the 30NM radius. Upon initial call-up, ground has a transponder code for me. After take off we are handed over to departure control who then asks us what our on-course heading is. You don't have to go where you "filed" to. You file to a VOR just to keep their computers happy.
To return into the 30NM radius, you contact the approach controlers. Don't bother calling the flight service center to open your plan, it's not like a typical VFR flight plan. The approach controllers handle you up to a certain point and hand you off to the local tower. DON'T set 1200 in the txponder!! Remain on the same code they gave you as you switch to tower.
Anyways, I'm sure they'll have their own way of doing things where you are. What I wrote here was how this has evolved here in NY. It seemed like they were inventing stuff as they went.....Good luck!
