Narrative:

I was approaching leesburg airport in virginia from the west with a student onboard. The student was flying at the time. Jyo was landing south on runway 17. We made our calls as usual from 10 miles northwest and proceeded toward our usual path to set up for 45 to downwind; left traffic runway 17. Our path begins over the ridgeline; then north of route 7 and tracking toward the white water tower then the blue water tower; then south toward the two quarries and then a 135 degree right turn to 45 to left downwind runway 17. About 4-5 miles north of the airport I see and hear traffic turning base for 17 no issue. I also notice a large twin piper well outside of the traffic pattern at my altitude on downwind about to turn base. I also hear on the radio a cardinal report below 2000 ft (from my perspective he was at tpa 1200 ft) circling around the blue water tower taking pictures. Anyone who flies in this area knows not to loiter around the blue water when jyo is landing south because everyone entering the pattern is aiming for it to set up for 45 to downwind and I believe this is why the twin piper was further north and west than normal trying to keep their distance from this cardinal. I start calling the twin on the radio since I do not recall hearing him before and began a diving right turn for spacing as I could not climb into dulles' class B (1500 ft floor) or maneuver much to the north washington ADIZ or continue straight ahead into the twin (cardinal taking pictures and dc ADIZ east border again). I continue and observe the aircraft taking pictures in a very bad place. This type of incursion has happened many times before (as I hear people complain about it) with aircraft on downwind and aircraft trying to enter the pattern and I don't want to be the first victim. I really think that now since the ADIZ has changed and everyone is scared of getting outside the jyo dc ADIZ maneuvering area we are (myself included) staying closer than normal and the extra plane in the way really made it a dangerous situation today. I think jyo needs to have right traffic for runway 17 since 90 percent of anyone coming here approaches from the west anyway to stay away from the approach corridor of iad; to stay away from the dc frz and to stay in the jyo dc ADIZ maneuvering area. It is not practical maneuvering northeast of the field anymore and I don't plan to do it again. Overflying the field is not the best either as iad class B starts at 1500 ft and flying too far south puts you at risk of drifting out of the jyo dc ADIZ maneuvering area. Risk my ticket one way or risk my life the other way. My other hope is that there would be established one and only way to enter jyo landing south because currently everyone does something different because of concerns with traffic conflict and ADIZ violation. It is not a good situation here and something needs to change. I honestly don't know what I should do next time I'm returning from the west but I'm leaning toward flying a right base to runway 17.callback conversation with reporter revealed the following information: the reporter stated that many local pilots are commenting about this new ADIZ development and are concerned about violation for ADIZ incursion. He decided to comment formally about it hoping to see a change to lessen the possibly of inadvertent ADIZ violations. A traffic pattern over the runway center with a left turn downwind would solve the problem of maneuvering any further to the east.

Title: A JYO INSTRUCTOR PLT COMMENTS THAT THE NEW POTOMAC ADIZ AND LOCAL TFC FORCE PILOTS TOO CLOSE TO THE ADIZ WHILE IN JYO'S RWY 17 TFC PATTERN. REQUESTS CONSIDERING A RIGHT RWY 17 PATTERN.

Narrative: I WAS APPROACHING LEESBURG AIRPORT IN VIRGINIA FROM THE WEST WITH A STUDENT ONBOARD. THE STUDENT WAS FLYING AT THE TIME. JYO WAS LANDING SOUTH ON RUNWAY 17. WE MADE OUR CALLS AS USUAL FROM 10 MILES NORTHWEST AND PROCEEDED TOWARD OUR USUAL PATH TO SET UP FOR 45 TO DOWNWIND; LEFT TRAFFIC RUNWAY 17. OUR PATH BEGINS OVER THE RIDGELINE; THEN NORTH OF ROUTE 7 AND TRACKING TOWARD THE WHITE WATER TOWER THEN THE BLUE WATER TOWER; THEN SOUTH TOWARD THE TWO QUARRIES AND THEN A 135 DEGREE RIGHT TURN TO 45 TO LEFT DOWNWIND RUNWAY 17. ABOUT 4-5 MILES NORTH OF THE AIRPORT I SEE AND HEAR TRAFFIC TURNING BASE FOR 17 NO ISSUE. I ALSO NOTICE A LARGE TWIN PIPER WELL OUTSIDE OF THE TRAFFIC PATTERN AT MY ALTITUDE ON DOWNWIND ABOUT TO TURN BASE. I ALSO HEAR ON THE RADIO A CARDINAL REPORT BELOW 2000 FT (FROM MY PERSPECTIVE HE WAS AT TPA 1200 FT) CIRCLING AROUND THE BLUE WATER TOWER TAKING PICTURES. ANYONE WHO FLIES IN THIS AREA KNOWS NOT TO LOITER AROUND THE BLUE WATER WHEN JYO IS LANDING SOUTH BECAUSE EVERYONE ENTERING THE PATTERN IS AIMING FOR IT TO SET UP FOR 45 TO DOWNWIND AND I BELIEVE THIS IS WHY THE TWIN PIPER WAS FURTHER NORTH AND WEST THAN NORMAL TRYING TO KEEP THEIR DISTANCE FROM THIS CARDINAL. I START CALLING THE TWIN ON THE RADIO SINCE I DO NOT RECALL HEARING HIM BEFORE AND BEGAN A DIVING RIGHT TURN FOR SPACING AS I COULD NOT CLIMB INTO DULLES' CLASS B (1500 FT FLOOR) OR MANEUVER MUCH TO THE NORTH WASHINGTON ADIZ OR CONTINUE STRAIGHT AHEAD INTO THE TWIN (CARDINAL TAKING PICTURES AND DC ADIZ EAST BORDER AGAIN). I CONTINUE AND OBSERVE THE AIRCRAFT TAKING PICTURES IN A VERY BAD PLACE. THIS TYPE OF INCURSION HAS HAPPENED MANY TIMES BEFORE (AS I HEAR PEOPLE COMPLAIN ABOUT IT) WITH AIRCRAFT ON DOWNWIND AND AIRCRAFT TRYING TO ENTER THE PATTERN AND I DON'T WANT TO BE THE FIRST VICTIM. I REALLY THINK THAT NOW SINCE THE ADIZ HAS CHANGED AND EVERYONE IS SCARED OF GETTING OUTSIDE THE JYO DC ADIZ MANEUVERING AREA WE ARE (MYSELF INCLUDED) STAYING CLOSER THAN NORMAL AND THE EXTRA PLANE IN THE WAY REALLY MADE IT A DANGEROUS SITUATION TODAY. I THINK JYO NEEDS TO HAVE RIGHT TRAFFIC FOR RUNWAY 17 SINCE 90 PERCENT OF ANYONE COMING HERE APPROACHES FROM THE WEST ANYWAY TO STAY AWAY FROM THE APPROACH CORRIDOR OF IAD; TO STAY AWAY FROM THE DC FRZ AND TO STAY IN THE JYO DC ADIZ MANEUVERING AREA. IT IS NOT PRACTICAL MANEUVERING NORTHEAST OF THE FIELD ANYMORE AND I DON'T PLAN TO DO IT AGAIN. OVERFLYING THE FIELD IS NOT THE BEST EITHER AS IAD CLASS B STARTS AT 1500 FT AND FLYING TOO FAR SOUTH PUTS YOU AT RISK OF DRIFTING OUT OF THE JYO DC ADIZ MANEUVERING AREA. RISK MY TICKET ONE WAY OR RISK MY LIFE THE OTHER WAY. MY OTHER HOPE IS THAT THERE WOULD BE ESTABLISHED ONE AND ONLY WAY TO ENTER JYO LANDING SOUTH BECAUSE CURRENTLY EVERYONE DOES SOMETHING DIFFERENT BECAUSE OF CONCERNS WITH TRAFFIC CONFLICT AND ADIZ VIOLATION. IT IS NOT A GOOD SITUATION HERE AND SOMETHING NEEDS TO CHANGE. I HONESTLY DON'T KNOW WHAT I SHOULD DO NEXT TIME I'M RETURNING FROM THE WEST BUT I'M LEANING TOWARD FLYING A RIGHT BASE TO RUNWAY 17.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT MANY LOCAL PILOTS ARE COMMENTING ABOUT THIS NEW ADIZ DEVELOPMENT AND ARE CONCERNED ABOUT VIOLATION FOR ADIZ INCURSION. HE DECIDED TO COMMENT FORMALLY ABOUT IT HOPING TO SEE A CHANGE TO LESSEN THE POSSIBLY OF INADVERTENT ADIZ VIOLATIONS. A TFC PATTERN OVER THE RWY CENTER WITH A LEFT TURN DOWNWIND WOULD SOLVE THE PROBLEM OF MANEUVERING ANY FURTHER TO THE EAST.
