Narrative:

I flew instruments to jyo. I wasn't thinking about the ADIZ at this point and realize now that I was able to get into jyo without problems because I was on an instrument flight plan. This meant I was squawking a discrete transponder code and talking to ATC. I normally always call FSS before a flight, but I was basing my go/no-go decision on WX from the morning briefing and the look of the sky. I decided it was safe to go. Again, I didn't think about the ADIZ over jyo and there was nothing to jog my memory to think about it. I was listening to the unicom frequency and reporting my position. As I climbed out of pattern altitude from jyo and proceeded on my direct course to frederick, I contacted potomac approach for flight following. I was surprised by the annoyed sound of the controller's voice and concerned when asked to make an immediate left turn to 350 degrees. I complied. Shortly thereafter, the controller came back to me and gave me a phone number to call when I landed for possible 'pilot deviation' because I was squawking 1200. I later contacted potomac approach control. While it doesn't lessen my sin, I learned that the potomac facility has dealt with over 230 cases of pilot deviation in the past few months. I learned that there have been approximately 1100 such incidents since 9/tue/01. Over 40 were military flts, several hundred were commercial operations, and about 1/3 were GA. I felt very bad that I contributed to an increase of the number of GA occurrences. I was aware of the tfr over washington. I read about the tfr and realized that I would not be able to fly into college park (cgs) as I was not based there. I have to admit that I was confused about the difference between the ADIZ and tfr areas and flight restr zones.

Title: A VERY LOW TIME PA28-180 PLT VIOLATED THE DC ADIZ.

Narrative: I FLEW INSTS TO JYO. I WASN'T THINKING ABOUT THE ADIZ AT THIS POINT AND REALIZE NOW THAT I WAS ABLE TO GET INTO JYO WITHOUT PROBS BECAUSE I WAS ON AN INST FLT PLAN. THIS MEANT I WAS SQUAWKING A DISCRETE XPONDER CODE AND TALKING TO ATC. I NORMALLY ALWAYS CALL FSS BEFORE A FLT, BUT I WAS BASING MY GO/NO-GO DECISION ON WX FROM THE MORNING BRIEFING AND THE LOOK OF THE SKY. I DECIDED IT WAS SAFE TO GO. AGAIN, I DIDN'T THINK ABOUT THE ADIZ OVER JYO AND THERE WAS NOTHING TO JOG MY MEMORY TO THINK ABOUT IT. I WAS LISTENING TO THE UNICOM FREQ AND RPTING MY POS. AS I CLBED OUT OF PATTERN ALT FROM JYO AND PROCEEDED ON MY DIRECT COURSE TO FREDERICK, I CONTACTED POTOMAC APCH FOR FLT FOLLOWING. I WAS SURPRISED BY THE ANNOYED SOUND OF THE CTLR'S VOICE AND CONCERNED WHEN ASKED TO MAKE AN IMMEDIATE L TURN TO 350 DEGS. I COMPLIED. SHORTLY THEREAFTER, THE CTLR CAME BACK TO ME AND GAVE ME A PHONE NUMBER TO CALL WHEN I LANDED FOR POSSIBLE 'PLTDEV' BECAUSE I WAS SQUAWKING 1200. I LATER CONTACTED POTOMAC APCH CTL. WHILE IT DOESN'T LESSEN MY SIN, I LEARNED THAT THE POTOMAC FACILITY HAS DEALT WITH OVER 230 CASES OF PLTDEV IN THE PAST FEW MONTHS. I LEARNED THAT THERE HAVE BEEN APPROX 1100 SUCH INCIDENTS SINCE 9/TUE/01. OVER 40 WERE MIL FLTS, SEVERAL HUNDRED WERE COMMERCIAL OPS, AND ABOUT 1/3 WERE GA. I FELT VERY BAD THAT I CONTRIBUTED TO AN INCREASE OF THE NUMBER OF GA OCCURRENCES. I WAS AWARE OF THE TFR OVER WASHINGTON. I READ ABOUT THE TFR AND REALIZED THAT I WOULD NOT BE ABLE TO FLY INTO COLLEGE PARK (CGS) AS I WAS NOT BASED THERE. I HAVE TO ADMIT THAT I WAS CONFUSED ABOUT THE DIFFERENCE BTWN THE ADIZ AND TFR AREAS AND FLT RESTR ZONES.
