A CRJ200 PLT SUGGESTS CHARTING ENHANCEMENTS FOR DCA RWY 1/19 MT VERNON VISUAL APCHS INCLUDING ILS/GPS BACKUP AND MISSED APCH GUIDANCE.

Narrative

FIRST; I THINK THE MOUNT VERNON VISUAL SHOULD HAVE A MISSED APCH PROC. NORMALLY; THIS IS NOT REQUIRED FOR AN APCH LIKE THIS; HOWEVER; P-56; THE NOISE ABATEMENT PROCS; AND THE RECENT INCREASE IN AIR TFC MAKE IT A MUST. YOU COULD BORROW THE ONE FROM THE ILS 1 OR MAKE UP A NEW ONE. FOR EXAMPLE: 'CLB TO 500 FT; THEN CLBING TURN TO 2000 FT; FLY OVER THE POTOMAC RIVER CTRLINE TO THE GEORGETOWN RESERVOIR (DCA 4.0 DME); INTERCEPT THE DCA 328 DEG RADIAL OUTBOUND.' IF YOU DON'T LIKE THIS ONE BECAUSE OF THE POTENTIAL CONFLICT WITH DEP TFC; TRY SOMETHING LIKE: 'CLB TO 500 FT; THEN IMMEDIATE CLBING L TURN HDG 276 DEGS; CLB AND MAINTAIN 2000 FT.' SECOND; I THINK THE ILS SHOULD BE DEPICTED ON THE APCH AS A POSSIBLE NAVAID TO BE USED INSIDE THE DCA 5.6 DME ARC. CHANGE THE TEXTUAL DESCRIPTION OF THE APCH TO READ: 'MOUNT VERNON VISUAL RWY 1: ACFT MAY PROCEED VIA THE DCA VOR/DME R-189 (009 DEG INBOUND) TO DCA 5.6 DME; THEN FOLLOW THE POTOMAC RIVER AND/OR THE ILS 1 TO THE ARPT.' DCA IS A BUSY ARPT WITH UNIQUE AND CHALLENGING PLT PROCS TO A SHORT RWY WITH A QUICK TURNOFF. WHY NOT GIVE PLTS THE AID OF AN ILS GS TO REDUCE LNDG ROLLOUT AND EXPEDITE RWY TURNOFFS. IN MY OPINION; WE SHOULD ALSO CHANGE THE MOUNT VERNON VISUAL TO INCLUDE RWY 33. THIS IS BECAUSE IT HAS BECOME COMMONPLACE FOR ATC TO CLR YOU FOR THE MOUNT VERNON VISUAL AND THEN SUBSEQUENTLY CLR YOU TO LAND ON RWY 33. IT WOULD BE BEST TO DEPICT A GND TRACK. THE TEXT FOR SUCH AN APCH WOULD READ SOMETHING LIKE THIS: 'MOUNT VERNON VISUAL RWY 33: ACFT MAY PROCEED VIA THE DCA VOR/DME R-189 (009 DEG INBOUND) TO DCA 5.6 DME; THEN FOLLOW THE POTOMAC RIVER TO THE WOODROW WILSON BRIDGE (DCA 3.8 DME); THEN TURN R TO ENTER BASE LEG FOR RWY 33. INTERCEPT FINAL APCH TO RWY 33 AND REMAIN S OF THE DCA R-140 DEG (320 DEG INBOUND).' FINALLY; I THINK WE SHOULD SET UP A GPS OVERLAY FOR THE MOUNT VERNON VISUAL AND THE RIVER VISUAL RWY 19. THE VISUAL REFERENCES WOULD STILL BE PRIMARY BUT ADVISORY VNAV AND GLIDEPATH GUIDANCE WOULD BE AVAILABLE. THE FMS ON OUR PLANE HAS A GENERIC VISUAL TO RWY 19 THAT I BELIEVE GOES RIGHT THROUGH P-56. REPLACING IT WITH THE RIVER VISUAL 19 GPS OVERLAY WOULD MAKE SENSE.
