Response: THE FAA RESPONDED SAYING THEY HAVE: DEVELOPED A NEW PART 4 OF THE AIRMAN'S INFORMATION MANUAL IN JANUARY 1970 (GRAPHIC NOTICES AND SUPPLEMENTAL INFORMATION). AS GRAPHICS ARE MADE AVAILABLE, THEY ARE INCLUDED IN THE SEMIANNUAL PART 4 OR ARE CARRIED IN THE EVERY 28-DAY PART 3, UNTIL THEY CAN BE TRANSFERRED TO PART 4. DEVELOPED VARIOUS TYPES OF GRAPHIC DISPLAYS OF NORMAL IFR AND VFR ROUTES. DEVELOPED GRAPHICS FOR THE 22 LARGE TERMINAL HUBS. FIFTEEN ARE PUBLISHED IN THE AIM AND THE REMAINING SEVEN ARE IN VARIOUS STAGES OF PROCESSING.DEVELOPED GRAPHICS FOR OTHER THAN LARGE HUBS INCLUDING AIR FORCE BASES. EIGHT ARE PUBLISHED IN THE AIM AND THREE ARE IN THE FINAL STAGES OF DEVELOPMENT. NINE OF THE ELEVEN DISPLAY AIR FORCE BASE ACTIVITIES. IN ADDITION TO THE ABOVE, THEY HAVE DEVELOPED A VFR TERMINAL AREA CHART WHICH THEY WILL BE EVALUATING. THIS CHART OF CHICAGO AREA DEPICTS THE TERMINAL CONTROL AREA, VFR AND IFR ROUTES AND MILITARY OPERATIONS AT NAS GLENVIEW. THE CHART IS DESIGNED FOR USE BY PILOTS AND FOR DISPLAY AT ALL AIRPORT AND OPERATIONAL BASES. AS A CONTINUATION OF THIS EXPANSION, THEY WILL COORDINATE FURTHER WITH THE DEPARTMENT OF DEFENSE TO INCORPORATE OTHER MILITARY BASES INTO THE PROGRAM.
