Narrative:

Another difficult transition through the dc ADIZ corridor. Approximately over gai, turned southeast for VFR transition through the remaining VFR slot between dca and bwi. Instructed to remain clear of class B. The corridor is only a few mi wide and difficult to navigation visually in hazy conditions even though I've been doing it for nearly 15 yrs. The ADIZ procedures were clearly designed by non pilots. The VFR corridor needs to be wider and higher. Turned south to correct for winds aloft. Even a few seconds in the turn put me dangerously close to flight restr zone. Stayed clear of flight restr zone on GPS apparently, but even at light airplane speeds, a small error is magnified in the reduced corridor. Passed a C150/152 opposite direction, same altitude. 200-300 ft to my right. No advisory given by ATC. They should have advised. We were both under control.

Title: GA PLT UNDER PCT CTL, EXPRESSED FRUSTRATION REGARDING THE DC ADIZ CORRIDOR AND EXPERIENCED NMAC DURING TRANSITION.

Narrative: ANOTHER DIFFICULT TRANSITION THROUGH THE DC ADIZ CORRIDOR. APPROX OVER GAI, TURNED SE FOR VFR TRANSITION THROUGH THE REMAINING VFR SLOT BTWN DCA AND BWI. INSTRUCTED TO REMAIN CLR OF CLASS B. THE CORRIDOR IS ONLY A FEW MI WIDE AND DIFFICULT TO NAV VISUALLY IN HAZY CONDITIONS EVEN THOUGH I'VE BEEN DOING IT FOR NEARLY 15 YRS. THE ADIZ PROCS WERE CLRLY DESIGNED BY NON PLTS. THE VFR CORRIDOR NEEDS TO BE WIDER AND HIGHER. TURNED S TO CORRECT FOR WINDS ALOFT. EVEN A FEW SECONDS IN THE TURN PUT ME DANGEROUSLY CLOSE TO FLT RESTR ZONE. STAYED CLR OF FLT RESTR ZONE ON GPS APPARENTLY, BUT EVEN AT LIGHT AIRPLANE SPDS, A SMALL ERROR IS MAGNIFIED IN THE REDUCED CORRIDOR. PASSED A C150/152 OPPOSITE DIRECTION, SAME ALT. 200-300 FT TO MY R. NO ADVISORY GIVEN BY ATC. THEY SHOULD HAVE ADVISED. WE WERE BOTH UNDER CTL.
