There is no mode C veil. Are you talking about the DC SFRA (Special Flight Rules Area)? That was there before ADS-B came about and is NOT a Class C veil. Yes, there is special use airspace, restricted areas, prohibited areas, MOA's, TFR's, etc. around the country.
Basically, ADS-B is required everywhere mode C is required except it's also required over and under class C. I don't remember exactly, but I don't think mode C is required under class C.
Tim,
OK, I promise I will do more research, but everyone here is breifing "Mode C veil" for adsb airspace in 2020. it exists now and will continue to after 2020 but with more restrictions. By that I mean if a person does not have adsb out, you cannot fly in that area except with special permission from ATC. This will be the "new line" to keep non adsb folks OUT of the area so they are not a hazard. (even if they do have a transponder)
The Mode C veils allow ATC to sequence aircraft which are adbs equippped...simply using the class B or C is too restrictive and small to move big, fast planes around. This will not go away in 2020, but will be enforced by the FAA. Anyone going inside will be in violation of a FAR - that is what we are being told around here at airport meetings all over the NE, Tim.
For example, I cannot fly under or over a class C or B shelf after 2020...must have adsb to even be near them.
If what you are saying is ground truth, I will withdraw my statement about the airspace, as that is a major sticking point with many around here...
I think we simply disagree on this, but I promise to do more research as I am willing to admit I may be wrong.
I will try to contact my FSDO for a clarification, but would appreciate if others who might know for sure would please chime in on this dialog.
Most appreciated! Thanks for the great discussion.
Mike

I fly regularly out a Mode C Veil. Both Tampa and Orlando have their own Mode C Veil. That is the Only airspace that ADS-B is mandated.

You're right, there is a 30 nm mode C ring around many of the Class C's. I guess I'll need to read the FAR for ADS-B and see what it says about that. I haven't seen anything saying ADS-B is required within a 30 nm ring around Class C.
