Hoping someone can help me better understand the ADIZ:

Why is there an inner AND outer line for the ADIZ? I thought it was just one line and if you cross it then you’ve exited or entered the country's airspace. What is the no-man’s-land in between the inner and outer marker of the ADIZ? And must you be on a DVFR flight plan to cross over the INNER boundary of the ADIZ? For example, if you’re flying VFR from Fort Myers to Key West OR from Tampa to New Orleans, can you cross that inner boundary without filing a flight plan and you’re okay so long as you don’t go outside of the outer boundary?
 
That is the zone. Except on the Mexican border the zone is not a line.
 
Because it's an ADIZ - Air Defense Identification Zone. If there weren't two lines with a "no-man's-land" in between, it'd be the ADIL or air defense identification line. :D

I don't think you want to be flying into that area without a flight plan.
 
Prolly cuz they don’t want airplane parts raining down on US peoplz when they get blowed up. Shoot em down before they cross a more internal line. Maybe.
 
Ha-ha. No one gets shot down. Would appreciate factual insight if anyone has it.
 
I treat it as one big line. Don’t have an answer for you regarding transgressions over the inner boundary. Go do it and report back. If nothing bad happens you should go multiple times to validate the data.

This is the factual insight. It's a zone in which you can be identified as friend or foe.

I’ve seen a few ADIZ violations in the east coast (SC coast) on radar. No one gets shoot down. NORAD working with the off shore agency (FACSFAC) has a line to ANG and they send fighters to intercept. It’s really a non event…unless you’re the GA pilot who didn’t file a DVFR / IFR flight plan.

I think it is a zone with two sides, because if it was just a line it would go forever all the way around the Earth. Air defense would have to be identifying aircraft everywhere in the world. So, if you enter the zone from either side, you are subject to being identified. If you can sneak all the way through the zone without being identified, I'm sure someone would want to know about that, too.
 
It varies from zero (along the Mexican Border) to over 50 miles wide at places (like coming in toward Manhattan).
So, how do we define the "zone" along the Mexican border?

Historical context: During the height of the Cold War, the ADIZ was a major daily fact of life, even in many domestic flights. It was figured that the Russkies were least likely to attack us from the south, so the Southern Border ADIZ was just a line even then. This from a 1958 sectional chart:

No Gulf of Mexico ADIZ? We're defenseless against Cuba.

Check AIM 5−6−1 for ADIZ Requirements, including …

c. Operational requirements for aircraft operations associated with an ADIZ are as follows:
1. Flight Plan. Except as specified in subparagraphs d and e below, an IFR or DVFR flight plan must be filed with an appropriate aeronautical facility as follows:
(a) Generally, for all operations that enter an ADIZ.
(b) For operations that will enter or exit the U.S. and which will operate into, within or across the Contiguous U.S. ADIZ regardless of true airspeed.

The AIM amplifies the procedure, but 99.11 casts it into stone. Entering the zone (that is crossing any of the lines) or operating within or from an airport within requires the appropriate flight plan.
